+# UDPStreamer Wire Protocol
+
+This document specifies the binary protocol used between UDPStreamer (server) and any
+compatible client (the included Go WebUI, a Python script, etc.).
+
+All multi-byte integers are **little-endian**.
+
+---
+
+## Packet Header (17 bytes, packed)
+
+Every datagram begins with a 17-byte header:
+
+```
+Offset  Size  Type    Field
+──────  ────  ──────  ────────────────────────────────────────────────────
+0       4     uint32  magic          = 0x53504455  ('UDPS' LE)
+4       1     uint8   type           see Packet Types below
+5       4     uint32  counter        per-update sequence number
+                                     (same across all fragments of one update)
+9       2     uint16  fragmentIdx    0-based index of this fragment
+11      2     uint16  totalFragments number of fragments for this update
+13      4     uint32  payloadBytes   bytes of payload following this header
+```
+
+**Total header size:** 17 bytes  
+**Magic:** `0x55 0x44 0x50 0x53` (`UDPS`)
+
+---
+
+## Packet Types
+
+| Value | Direction | Name | Description |
+|-------|-----------|------|-------------|
+| 0 | Server → Client | DATA | Signal data (may be fragmented) |
+| 1 | Server → Client | CONFIG | Signal metadata sent on connect |
+| 2 | Client → Server | ACK | Acknowledge a data counter (reserved) |
+| 3 | Client → Server | CONNECT | Request a session |
+| 4 | Client → Server | DISCONNECT | End the session |
+
+---
+
+## Session Flow
+
+```
+Client                                Server
+──────                                ──────
+                CONNECT (type=3) →
+              ← CONFIG  (type=1)
+              ← DATA    (type=0)  ┐
+              ← DATA    (type=0)  │  repeated every RT cycle
+              ← DATA    (type=0)  ┘
+                DISCONNECT (type=4) →
+```
+
+1. Client sends a 17-byte CONNECT packet (`payloadBytes = 0`).
+2. Server responds immediately with one or more CONFIG fragments describing all signals.
+3. Server sends DATA fragments on every `Synchronise()` call while a client is connected.
+4. Client sends DISCONNECT to terminate cleanly. A new CONNECT replaces an existing session.
+
+---
+
+## CONFIG Payload
+
+The CONFIG payload is sent as one or more fragmented packets (`type = 1`).
+After reassembly the layout is:
+
+```
+Offset  Size  Type     Field
+──────  ────  ───────  ────────────────────────────────────
+0       4     uint32   numSignals
+── for each signal (136 bytes) ──────────────────────────────
+0       64    char[64] name           null-terminated
+64      1     uint8    typeCode       see Type Codes
+65      1     uint8    quantType      see Quantization Types
+66      1     uint8    numDimensions  0 = scalar, 1 = 1-D array, 2 = matrix
+67      4     uint32   numRows        0 or 1 for scalar/1-D
+71      4     uint32   numCols        number of elements along fastest axis
+75      8     float64  rangeMin
+83      8     float64  rangeMax
+91      1     uint8    timeMode       see Time Modes
+92      8     float64  samplingRate   Hz (0 if PacketTime)
+100     4     uint32   timeSignalIdx  index of the time-reference signal;
+                                      0xFFFFFFFF = PacketTime (no reference)
+104     32    char[32] unit           null-terminated physical unit string
+── (total per signal: 136 bytes) ────────────────────────────
+```
+
+### Type Codes
+
+| Code | C type | Bytes/element |
+|------|--------|---------------|
+| 0 | uint8 | 1 |
+| 1 | int8 | 1 |
+| 2 | uint16 | 2 |
+| 3 | int16 | 2 |
+| 4 | uint32 | 4 |
+| 5 | int32 | 4 |
+| 6 | uint64 | 8 |
+| 7 | int64 | 8 |
+| 8 | float32 | 4 |
+| 9 | float64 | 8 |
+
+### Quantization Type Codes (wire side)
+
+| Code | Wire type | Description |
+|------|-----------|-------------|
+| 0 | — | No quantization; raw type as above |
+| 1 | uint8 | Linear map `[rangeMin, rangeMax]` → `[0, 255]` |
+| 2 | int8 | Linear map `[rangeMin, rangeMax]` → `[-127, 127]` |
+| 3 | uint16 | Linear map `[rangeMin, rangeMax]` → `[0, 65535]` |
+| 4 | int16 | Linear map `[rangeMin, rangeMax]` → `[-32767, 32767]` |
+
+### Time Mode Codes
+
+| Code | Name | Meaning |
+|------|------|---------|
+| 0 | PacketTime | HRT timestamp at `Synchronise()` — see DATA payload |
+| 1 | FullArray | `timeSignalIdx` signal has same `numElements`; element `[k]` time = `timeSignal[k]` |
+| 2 | FirstSample | `timeSignalIdx` is scalar; `t[k] = t[0] + k / samplingRate` |
+| 3 | LastSample | `timeSignalIdx` is scalar; `t[k] = t[N-1] - (N-1-k) / samplingRate` |
+
+---
+
+## DATA Payload
+
+After reassembly, the DATA payload layout is:
+
+```
+Offset  Size  Type    Field
+──────  ────  ──────  ────────────────────────────────────────────────────
+0       8     uint64  hrtTimestamp   hardware reference timer count at Synchronise()
+── for each signal (in config order) ────────────────────────────────────
+varies  N×sz  —       signal data    N = numRows×numCols, sz = element size
+                                     (wire size if quantized, raw size otherwise)
+```
+
+Signal data for quantized signals uses the wire element size (see Quantization Type Codes),
+not the original MARTe2 type size.
+
+### Dequantization
+
+To recover physical values from quantized integers:
+
+```
+// uint16 → float
+span      = rangeMax - rangeMin
+physical  = rangeMin + (wire_uint16 / 65535.0) × span
+
+// int16 → float
+physical  = rangeMin + ((wire_int16 + 32767) / 65534.0) × span
+```
+
+---
+
+## Fragmentation
+
+When a payload exceeds `MaxPayloadSize` bytes, it is split into fragments:
+
+```
+chunkSize   = MaxPayloadSize - 17   // usable bytes per datagram
+numFragments = ceil(payloadSize / chunkSize)
+```
+
+Fragment `i` carries bytes `[i × chunkSize .. min((i+1) × chunkSize, payloadSize))`.
+All fragments share the same `counter`; `fragmentIdx` and `totalFragments` allow
+the client to reassemble them in any order.
+
+**Example:** `MaxPayloadSize = 1400`, payload = 8016 B  
+→ `chunkSize = 1383`, `numFragments = ceil(8016/1383) = 6`
+
+---
+
+## Minimal Python Client Example
+
+```python
+import socket, struct, time
+
+MAGIC    = 0x53504455
+HDR_FMT  = '<IBHHI'     # magic, type, counter, fragIdx, totalFrags, payloadBytes
+HDR_SIZE = 17
+
+def build_connect():
+    return struct.pack(HDR_FMT, MAGIC, 3, 0, 0, 1, 0)
+
+def parse_header(data):
+    return struct.unpack_from(HDR_FMT, data)
+
+sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
+sock.bind(('', 44900))
+sock.sendto(build_connect(), ('127.0.0.1', 44500))
+sock.settimeout(5.0)
+
+fragments = {}
+while True:
+    data, _ = sock.recvfrom(65536)
+    magic, ptype, counter, frag_idx, total_frags, payload_bytes = parse_header(data)
+    payload = data[HDR_SIZE:]
+
+    if ptype == 1:   # CONFIG
+        print(f"CONFIG fragment {frag_idx+1}/{total_frags}")
+    elif ptype == 0: # DATA
+        fragments.setdefault(counter, {})[frag_idx] = payload
+        if len(fragments[counter]) == total_frags:
+            full = b''.join(fragments.pop(counter)[i] for i in range(total_frags))
+            hrt = struct.unpack_from('<Q', full)[0]
+            print(f"DATA counter={counter} hrt={hrt} payload={len(full)}B")

+# SineArrayGAM
+
+`SineArrayGAM` is a helper GAM bundled with the UDPStreamer library. It fills a `float32`
+output array with a continuous sinusoidal waveform, maintaining phase continuity across
+RT cycles. It is intended for testing and demonstrating the UDPStreamer's packed-burst
+signal capability.
+
+> **Library:** The class is compiled into `UDPStreamer.so` alongside the UDPStreamer
+> DataSource. A `SineArrayGAM.so → UDPStreamer.so` symlink is required for MARTe2's
+> auto-loader (created automatically by `Test/MARTeApp/run.sh`).
+
+---
+
+## Configuration
+
+```
++Ch1GAM = {
+    Class        = SineArrayGAM
+    Frequency    = 1000.0       // Signal frequency [Hz]  (default: 1.0)
+    Amplitude    = 1.0          // Peak amplitude           (default: 1.0)
+    Offset       = 0.0          // DC offset                (default: 0.0)
+    Phase        = 0.0          // Initial phase [radians]  (default: 0.0)
+    SamplingRate = 1000000.0    // Sample rate [Hz]         (default: 1000000.0)
+                                //   Must match the SamplingRate declared in the
+                                //   UDPStreamer signal config.
+
+    OutputSignals = {
+        Ch1 = {
+            DataSource       = DDB
+            Type             = float32
+            NumberOfDimensions = 1
+            NumberOfElements = 1000   // N samples per RT cycle
+        }
+    }
+}
+```
+
+### Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `Frequency` | float64 | 1.0 | Signal frequency in Hz |
+| `Amplitude` | float64 | 1.0 | Peak amplitude (half peak-to-peak) |
+| `Offset` | float64 | 0.0 | DC offset added to every sample |
+| `Phase` | float64 | 0.0 | Phase shift in radians |
+| `SamplingRate` | float64 | 1 000 000.0 | Sample rate in Hz; must be > 0 |
+
+### Output signal
+
+Exactly **one** output signal of type **`float32`** is required. The signal must have
+`NumberOfDimensions = 1` and `NumberOfElements = N` where N ≥ 1.
+
+---
+
+## Waveform formula
+
+Each `Execute()` call fills elements `[0 .. N-1]` using:
+
+```
+v[k] = Amplitude × sin(2π × Frequency × (offset_total + k) / SamplingRate + Phase) + Offset
+```
+
+where `offset_total` is a cumulative sample counter that increments by `N` after each call.
+This guarantees a gapless, phase-continuous waveform across RT cycles.
+
+---
+
+## Bandwidth and fragmentation
+
+For a 1 MSps burst at 10 kHz RT rate with 1000 samples per cycle:
+
+```
+N = SamplingRate / RT_rate = 1 000 000 / 1000 = 1000 samples per cycle
+Wire bytes = 1000 × 4 (float32) = 4000 B per channel per cycle
+At 10 kHz: 4000 × 10 000 = 40 MB/s raw (UDP, before quantization)
+```
+
+Using `QuantizedType = uint16` halves the wire bandwidth to 20 MB/s.
+With `MaxPayloadSize = 1400` the 4 000-byte payload spans 3 UDP datagrams
+(`ceil(4008 / 1383) = 3`).
+
+---
+
+## Example: two-channel quadrature pair
+
+```
++Ch1GAM = {
+    Class = SineArrayGAM
+    Frequency = 1000.0; Amplitude = 1.0; Phase = 0.0; SamplingRate = 10000000.0
+    OutputSignals = {
+        Ch1 = { DataSource = DDB; Type = float32; NumberOfDimensions = 1; NumberOfElements = 1000 }
+    }
+}
+
++Ch2GAM = {
+    Class = SineArrayGAM
+    Frequency = 1000.0; Amplitude = 1.0; Phase = 1.5708; SamplingRate = 10000000.0
+    OutputSignals = {
+        Ch2 = { DataSource = DDB; Type = float32; NumberOfDimensions = 1; NumberOfElements = 1000 }
+    }
+}
+```
+
+This produces two signals 90° out of phase, useful for verifying IQ-style signal chains.

+# Tutorial: Streaming Signals with UDPStreamer
+
+This tutorial walks you through:
+
+1. Setting up the environment
+2. Running the demo application
+3. Visualising signals in the browser
+4. Adding UDPStreamer to your own MARTe2 application
+5. Streaming high-frequency packed signals
+
+**Prerequisites:** MARTe2 and MARTe2-components must already be built.
+See the [MARTe2 installation guide](https://vcis.f4e.europa.eu/marte2-docs/) if needed.
+
+---
+
+## 1. Environment Setup
+
+Edit `marte_env.sh` in the repository root to point at your MARTe2 installations:
+
+```bash
+# marte_env.sh (key variables)
+export MARTe2_DIR="$HOME/workspace/MARTe2"
+export MARTe2_Components_DIR="$HOME/workspace/MARTe2-components"
+```
+
+Then source it in your shell:
+
+```bash
+cd /path/to/MARTe_IO_components
+source marte_env.sh
+```
+
+Verify the environment is correct:
+
+```bash
+echo $MARTe2_DIR
+ls $MARTe2_DIR/Build/x86-linux/App/MARTeApp.ex    # should exist
+```
+
+---
+
+## 2. Running the Demo Application
+
+The demo is in `Test/MARTeApp/`. It runs a 10 kHz MARTe2 application that streams:
+
+- **Counter** and **Time** — scalar counters from the Linux timer
+- **Sine1** — 1 Hz sine wave (float32, amplitude 10, quantized to uint16 on wire)

+
+Start everything with one command:
+
+```bash
+cd Test/MARTeApp
+./run.sh --webui
+```
+
+The script will:
+1. Build the UDPStreamer shared library.
+2. Build the Go WebUI binary (first run only).
+3. Start the WebUI relay on `http://localhost:8080`.
+4. Launch the MARTe2 application.
+
+Press `Ctrl+C` to stop both processes.
+
+---
+
+## 3. Visualising Signals in the Browser
+
+Open `http://localhost:8080` in any modern browser.
+
+### Add your first plot
+
+1. Click **+ Add Plot** in the toolbar.
+2. A blank plot panel appears with a "Drop signals here" hint.
+
+### Plot a signal
+
+1. In the left sidebar find **Sine1** (listed as `Sine1 · f32`).
+2. Click and drag it onto the plot panel.
+3. The sine wave appears immediately.
+
+### Overlay multiple signals
+
+Drag **Sine2** onto the same plot — it is added as a second trace.
+
+### Adjust the time window
+
+Use the **Window** dropdown in the top bar to change the rolling display window
+(1 s, 5 s, 10 s, 30 s, 60 s).
+
+### Plot layout
+
+Use the layout buttons (`1×1`, `2×1`, `2×2`, …) to split the screen into multiple
+plot panels. Each panel is independent — drag different signals onto each.
+
+### High-frequency signals
+
+Drag **Ch1** (shown as `Ch1 · [1000] f32`) onto a plot. Each UDP packet carries
+1000 samples at 10 MSps; the WebUI reconstructs per-sample timestamps and displays
+the continuous waveform.
+
+### Export data
+
+Click **⬇** on any plot to download the visible window as a CSV file.

+
+## 4. Adding UDPStreamer to Your Own Application
+
+### Step 1 — Declare the DataSource
+
+Add UDPStreamer to the `+Data` section of your MARTe2 configuration:
+
+```
++Data = {
+    Class = ReferenceContainer
+    DefaultDataSource = DDB
+
+    +DDB = { Class = GAMDataSource }
+
+    +Streamer = {
+        Class          = UDPStreamer
+        Port           = 44500
+        MaxPayloadSize = 1400
+
+        Signals = {
+            Voltage = {
+                Type     = float32
+                Unit     = "V"
+                RangeMin = -10.0
+                RangeMax = 10.0
+                QuantizedType = uint16      // 16-bit quantized on wire
+            }
+            Current = {
+                Type = float32
+                Unit = "A"
+            }
+        }
+    }
+
+    +Timings = { Class = TimingDataSource }
+}
+```
+
+### Step 2 — Route signals with IOGAM
+
+Use IOGAM to copy signals from your inter-GAM DDB into the Streamer:
+
+```
++StreamerGAM = {
+    Class = IOGAM
+    InputSignals = {
+        Voltage = { DataSource = DDB; Type = float32 }
+        Current = { DataSource = DDB; Type = float32 }
+    }
+    OutputSignals = {
+        Voltage = { DataSource = Streamer; Type = float32 }
+        Current = { DataSource = Streamer; Type = float32 }
+    }
+}
+```
+
+Add `StreamerGAM` at the **end** of the thread's `Functions` list so it runs after
+your control GAMs have written their outputs.
+
+### Step 3 — Add the library to LD_LIBRARY_PATH
+
+In your run script, add the UDPStreamer build directory:
+
+```bash
+export LD_LIBRARY_PATH="/path/to/Build/x86-linux/Components/DataSources/UDPStreamer:$LD_LIBRARY_PATH"
+```
+
+### Step 4 — Start the WebUI and connect
+
+```bash
+# From the Client/WebUI directory:
+./udpstreamer-webui --streamer 127.0.0.1:44500 --listen :8080 --clientport 44900
+```
+
+Open `http://localhost:8080`, drag your signals onto a plot, and you're done.
+

+
+## 5. Streaming High-Frequency Packed Signals
+
+This section shows how to stream 1000 samples per RT cycle at 1 MSps.
+
+### Overview
+
+At 1 kHz RT rate with 1000 samples per cycle the effective sample rate is 1 MSps.
+Each UDP packet carries a burst of 1000 samples; the client reconstructs timestamps
+using the anchor timestamp and `SamplingRate`.
+
+### Step 1 — Generate burst data with SineArrayGAM
+
+`SineArrayGAM` (bundled in `UDPStreamer.so`) produces a continuous float32 array:
+
+```
++Ch1GAM = {
+    Class        = SineArrayGAM
+    Frequency    = 1000.0       // 1 kHz signal
+    Amplitude    = 1.0
+    Phase        = 0.0
+    SamplingRate = 1000000.0    // must match Streamer config below
+    OutputSignals = {
+        Ch1 = {
+            DataSource         = DDB
+            Type               = float32
+            NumberOfDimensions = 1
+            NumberOfElements   = 1000
+        }
+    }
+}
+```
+
+### Step 2 — Add a time reference signal
+
+Add a scalar time signal that will anchor the first sample's timestamp:
+
+```
++TimerGAM = {
+    Class = IOGAM
+    InputSignals = {
+        Time = { DataSource = Timer; Type = uint32; Frequency = 1000 }
+    }
+    OutputSignals = {
+        Time = { DataSource = DDB; Type = uint32 }
+    }
+}
+```
+
+### Step 3 — Configure UDPStreamer for packed signals
+
+```
++Streamer = {
+    Class          = UDPStreamer
+    Port           = 44500
+    MaxPayloadSize = 1400
+
+    Signals = {
+        Time = { Type = uint32; Unit = "us" }   // time reference (scalar)
+
+        Ch1 = {
+            Type               = float32
+            NumberOfDimensions = 1
+            NumberOfElements   = 1000
+            Unit               = "V"
+            TimeMode           = FirstSample    // Time = timestamp of first sample
+            TimeSignal         = Time
+            SamplingRate       = 1000000.0      // Hz
+        }
+    }
+}
+```
+
+### Step 4 — Wire everything in the thread
+
+```
++Thread1 = {
+    Class     = RealTimeThread
+    Functions = { TimerGAM Ch1GAM StreamerGAM }
+}
+```
+
+Where `StreamerGAM` is the IOGAM that copies `Time` and `Ch1` from DDB to Streamer.
+
+### Step 5 — Fragmentation note
+
+A single 1000-element float32 channel plus a uint32 time signal produces:
+
+```
+payload = 8 B (HRT) + 4 B (Time/uint32) + 4000 B (float32×1000) = 4012 B
+```
+
+With `MaxPayloadSize = 1400`:
+
+```
+fragments = ceil(4012 / 1383) = 3 datagrams per cycle
+```
+
+At 1 kHz that is 3000 UDP datagrams/second per channel — well within typical LAN capacity.
+
+### Step 6 — Create the SineArrayGAM symlink
+
+MARTe2 tries to `dlopen("SineArrayGAM.so")` the first time it encounters the class.
+Create the symlink in your build directory:
+
+```bash
+UDPSTREAMER_LIB=/path/to/Build/x86-linux/Components/DataSources/UDPStreamer
+ln -sf "${UDPSTREAMER_LIB}/UDPStreamer.so" "${UDPSTREAMER_LIB}/SineArrayGAM.so"
+```
+
+---
+
+## 6. Writing a Custom UDP Client
+
+A minimal Python client that receives and prints signal data:
+
+```python
+import socket, struct
+
+MAGIC   = 0x53504455
+HDR     = struct.Struct('<IBHHI')   # 17 bytes: magic, type, counter, fragIdx, total, payloadBytes
+SERVER  = ('127.0.0.1', 44500)
+MY_PORT = 44900
+
+sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
+sock.bind(('', MY_PORT))
+sock.settimeout(5.0)
+
+# Send CONNECT
+sock.sendto(HDR.pack(MAGIC, 3, 0, 0, 1, 0), SERVER)
+print("CONNECT sent")
+
+reassembly = {}
+
+while True:
+    data, _ = sock.recvfrom(65536)
+    if len(data) < 17:
+        continue
+    magic, ptype, counter, frag_idx, total_frags, payload_bytes = HDR.unpack_from(data)
+    if magic != MAGIC:
+        continue
+    payload = data[17:17 + payload_bytes]
+
+    # Accumulate fragments
+    bucket = reassembly.setdefault((ptype, counter), {})
+    bucket[frag_idx] = payload
+    if len(bucket) < total_frags:
+        continue
+    full = b''.join(bucket[i] for i in range(total_frags))
+    del reassembly[(ptype, counter)]
+
+    if ptype == 1:   # CONFIG
+        num_sigs = struct.unpack_from('<I', full)[0]
+        print(f"CONFIG: {num_sigs} signals")
+    elif ptype == 0: # DATA
+        hrt = struct.unpack_from('<Q', full)[0]
+        print(f"DATA counter={counter} hrt={hrt} payload={len(full)}B")
+```
+
+For a full-featured client with CONFIG parsing and dequantization see
+[`Client/WebUI/protocol.go`](../Client/WebUI/protocol.go) (Go)
+and the [Protocol reference](Protocol.md).

+## Troubleshooting
+
+| Symptom | Cause | Fix |
+|---------|-------|-----|
+| `Failed dlopen(): UDPStreamer.so` | Library not in `LD_LIBRARY_PATH` | Add build dir to `LD_LIBRARY_PATH` |
+| `Failed dlopen(): WaveformSin.so` | Symlink missing | Run `run.sh`; it creates the symlinks automatically |
+| `Failed dlopen(): SineArrayGAM.so` | Symlink missing | Create `SineArrayGAM.so → UDPStreamer.so` in the build dir |
+| WebUI shows "No data for Xs" | UDPStreamer not running / wrong port | Check port numbers; check MARTe2 logs |
+| Plots only show ~167 ms of HF data | Browser buffer too small | Use `TEMPORAL_CAP` in JS (already 600 000 in current WebUI) |
+| Fragmentation error / missing data | MTU too small | Reduce `MaxPayloadSize` to 1200 or smaller |

+# UDPStreamer DataSource
+
+`UDPStreamer` is a MARTe2 output DataSource that streams signals from a real-time application
+to a single connected UDP client. It is fully asynchronous from the RT thread: the RT cycle
+only performs a fast spinlock + memcpy, while all network I/O runs on a dedicated background
+thread.
+
+## Key Features
+
+- **Zero-copy RT path** — `Synchronise()` only locks, copies signal memory, and posts a semaphore.
+- **Single-client model** — one client at a time; a new CONNECT replaces the previous session.
+- **Packet fragmentation** — large payloads are split into ≤ `MaxPayloadSize`-byte datagrams,
+  each with a header carrying fragment index and total count so the client can reassemble them.
+- **Signal quantization** — `float32`/`float64` signals can be linearly quantized to
+  `uint8`, `int8`, `uint16`, or `int16` on the wire, reducing bandwidth significantly.
+- **Temporal arrays** — signals with `NumberOfElements > 1` can carry per-sample time
+  metadata via `TimeMode` and `TimeSignal`, enabling high-frequency burst transmission
+  (e.g. 1 000 samples per RT cycle at 1 MSps).
+
+---
+
+## Configuration
+
+```
++Streamer = {
+    Class           = UDPStreamer
+
+    // Network
+    Port            = 44500        // UDP port the server listens on (default: 44500)
+    MaxPayloadSize  = 1400         // Maximum bytes per UDP datagram (default: 1400)
+                                   //   Must be > 17 (header size). Tune for MTU.
+
+    // Background thread (optional)
+    CPUMask         = 0x2          // CPU affinity mask for the network thread

+        Time = {
+            Type = uint32
+            Unit = "us"            // Optional: physical unit string (informational)
+        }
+
+        // ── Float signal with quantization ───────────────────────────────────
+        Pressure = {
+            Type         = float32
+            Unit         = "Pa"
+            RangeMin     = 0.0         // Required when QuantizedType is set

+            QuantizedType = uint16     // none | uint8 | int8 | uint16 | int16
+        }
+
+        // ── Temporal array (packed burst) ────────────────────────────────────
+        Channel1 = {
+            Type               = float32
+            NumberOfDimensions = 1
+            NumberOfElements   = 1000         // N samples per RT cycle

+            TimeSignal         = Time         // name of a scalar signal in this DataSource
+            SamplingRate       = 1000000.0    // Hz — used by client to reconstruct timestamps
+        }
+    }
+}
+```
+
+### Top-level Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `Port` | uint16 | 44500 | UDP server port |
+| `MaxPayloadSize` | uint32 | 1400 | Max payload bytes per UDP datagram (min 18) |
+| `CPUMask` | uint32 | 0 (any) | Background thread CPU affinity |
+| `StackSize` | uint32 | 1 048 576 | Background thread stack size in bytes |
+
+### Per-signal Parameters
+
+| Parameter | Type | Default | Applies to |
+|-----------|------|---------|------------|
+| `Unit` | string | `""` | Any type — informational, forwarded to client in CONFIG |
+| `RangeMin` | float64 | 0.0 | float32/float64 with `QuantizedType` |
+| `RangeMax` | float64 | 1.0 | float32/float64 with `QuantizedType` |
+| `QuantizedType` | string | `none` | float32/float64 only |
+| `TimeMode` | string | `PacketTime` | Signals with `NumberOfElements > 1` |
+| `TimeSignal` | string | — | Required when `TimeMode` ≠ `PacketTime` |
+| `SamplingRate` | float64 | 0.0 | Required when `TimeMode` = `FirstSample` or `LastSample` |
+
+### Quantization Types
+
+| Value | Wire type | Bit depth | Notes |
+|-------|-----------|-----------|-------|
+| `none` | same as source | — | Raw copy, no quantization |
+| `uint8` | uint8 | 8-bit | Maps `[RangeMin, RangeMax]` → `[0, 255]` |
+| `int8` | int8 | 8-bit | Maps `[RangeMin, RangeMax]` → `[-127, 127]` |
+| `uint16` | uint16 | 16-bit | Maps `[RangeMin, RangeMax]` → `[0, 65 535]` |
+| `int16` | int16 | 16-bit | Maps `[RangeMin, RangeMax]` → `[-32 767, 32 767]` |
+
+Quantization formula (unsigned, e.g. uint16):
+
+```
+normalized = clamp((value - RangeMin) / (RangeMax - RangeMin), 0.0, 1.0)
+wire_value = (uint16)(normalized × 65535)
+```
+
+### Time Modes
+
+| Value | Meaning | Requirements |
+|-------|---------|--------------|
+| `PacketTime` | The HRT counter captured at `Synchronise()` time is used as the packet timestamp. No per-signal time metadata. | — |
+| `FullArray` | `TimeSignal` carries one timestamp per element (same `NumberOfElements`). | `TimeSignal` must have the same `NumberOfElements`. |
+| `FirstSample` | `TimeSignal` is a scalar giving the timestamp of element `[0]`. Elements `[1..N-1]` are inferred at `1/SamplingRate` intervals. | Scalar `TimeSignal`; `SamplingRate > 0`. |
+| `LastSample` | Same as `FirstSample` but `TimeSignal` is the timestamp of element `[N-1]`. | Scalar `TimeSignal`; `SamplingRate > 0`. |
+
+---
+
+## Broker
+
+UDPStreamer uses `MemoryMapSynchronisedOutputBroker` for output signals. This broker is
+called automatically by the MARTe2 scheduler after all GAMs in the thread have executed.
+
+> **Note:** Input signals are not supported — `GetBrokerName()` returns `""` for
+> `InputSignals`.
+
+---
+
+## Lifecycle
+
+```
+PrepareNextState()          ← opens UDP server socket, starts background thread
+    ↓
+[RT thread, each cycle]
+    GAMs execute            ← write into Streamer signal memory via broker
+    Synchronise()           ← spinlock + memcpy to readyBuffer + post dataSem
+    ↓
+[Background thread]
+    Poll serverSocket       ← receive CONNECT / DISCONNECT / ACK
+    Wait dataSem            ← woken by Synchronise()
+    QuantizeAndSerialize()  ← build wire payload
+    SendFragmented()        ← send DATA fragments to client
+```
+
+---
+
+## Performance Notes
+
+- The RT path (`Synchronise()`) performs only: `FastLock()` + `memcpy` + `FastUnLock()` + `EventSem.Post()`.
+  No socket calls, no heap allocation.
+- `readyBuffer` and `wireBuffer` are allocated once in `AllocateMemory()`.
+- If no client is connected the background thread skips serialisation entirely.
+- Packet loss is tolerated silently. ACK tracking is reserved for future use.

+## Example: minimal scalar streaming
+
+```
++Data = {
+    Class = ReferenceContainer
+
+    +Streamer = {
+        Class = UDPStreamer
+        Port = 44500
+        Signals = {
+            Counter = { Type = uint32 }
+            Voltage = { Type = float32; Unit = "V"; RangeMin = -10.0; RangeMax = 10.0; QuantizedType = uint16 }
+        }
+    }
+}
+```
+
+## Example: high-frequency burst
+
+```
++Streamer = {
+    Class          = UDPStreamer
+    Port           = 44500
+    MaxPayloadSize = 1400
+
+    Signals = {
+        T0 = { Type = uint32; Unit = "us" }
+
+        Ch1 = {
+            Type               = float32
+            NumberOfDimensions = 1
+            NumberOfElements   = 1000        // 1000 samples per RT cycle
+            Unit               = "V"
+            TimeMode           = FirstSample
+            TimeSignal         = T0
+            SamplingRate       = 1000000.0   // 1 MSps
+        }
+    }
+}
+```
+
+With `MaxPayloadSize = 1400`, a single 1000-element float32 signal produces:
+
+```
+payload = 8 B (HRT timestamp) + 4 B (T0/uint32) + 4000 B (float32×1000) = 4012 B
+fragments = ceil(4012 / 1383) = 3

+
+### Signal Sidebar
+
+Signals received in the CONFIG packet are listed in the sidebar:
+
+- **Scalar signals** — appear as single draggable items (e.g. `Sine1 · f32`).
+- **Temporal arrays** — high-frequency burst signals with `TimeMode ≠ PacketTime`.
+  Displayed as a single draggable item showing element count: `Ch1 · [1000] f32`.
+- **Spatial arrays** — `TimeMode = PacketTime` arrays are shown as an expandable
+  group; individual elements (`Ch1[0]`, `Ch1[1]`, …) can be dragged independently.
+
+### Adding Plots
+
+1. Click **+ Add Plot** in the toolbar.
+2. Drag a signal from the sidebar onto a plot panel.
+3. Multiple signals can be overlaid on the same plot.
+4. Click the **×** badge to remove a trace.
+
+### Plot Controls
+
+| Control | Action |
+|---------|--------|
+| **⏸ / ▶** (per plot) | Pause / resume that plot; paused plots allow zoom and pan |
+| **⬇** (per plot) | Export all visible traces to CSV |
+| **🗑** (per plot) | Delete the plot |
+| **⏸ Pause All** (top bar) | Pause all plots simultaneously |
+| **Window** (top bar) | Adjust the rolling time window (1 s – 60 s) |
+| Layout buttons | Switch between 1×1, 2×1, 1×2, 2×2, 3×1, … grid layouts |
+| Sidebar **←** | Collapse the signal list to maximise plot area |
+
+### Status LED
+
+| Colour | Meaning |
+|--------|---------|
+| Red (solid) | No WebSocket connection to browser |
+| Orange (pulsing) | WebSocket connected but no data received in > 1 s |
+| Green (pulsing) | Data is being received normally |
+
+---
+
+## Architecture (Go side)
+
+### Goroutines
+
+```
+main()
+ ├── hub.Run()          ← event loop: register/unregister WS clients, batch data at 30 Hz
+ ├── udpClient.Run()    ← reconnects on silence; parses UDP packets; feeds hub.dataCh
+ └── http.ListenAndServe()
+      ├── GET /         ← serves embedded index.html
+      └── GET /ws       ← upgrades to WebSocket; launches per-client read/write pumps
+```
+
+### WebSocket Message Format
+
+All messages are JSON. Two types are sent from server to browser:
+
+#### `config` message
+
+Sent immediately when a browser client connects (if a CONFIG has been received from
+UDPStreamer) and whenever UDPStreamer sends a new CONFIG packet.
+
+```json
+{
+  "type": "config",
+  "signals": [
+    {
+      "name": "Sine1",
+      "typeCode": 8,
+      "quantType": 3,
+      "numDimensions": 0,
+      "numRows": 1,
+      "numCols": 1,
+      "rangeMin": -10.0,
+      "rangeMax": 10.0,
+      "timeMode": 0,
+      "samplingRate": 0.0,
+      "timeSignalIdx": 4294967295,
+      "unit": "V"
+    }
+  ]
+}
+```
+
+#### `data` message
+
+Sent at ≤ 30 Hz, batching all UDP packets received since the last tick.
+Each signal carries its own time axis to support mixed scalar + temporal-array signals.
+
+```json
+{
+  "type": "data",
+  "signals": {
+    "Sine1":    { "t": [1747123456.001, 1747123456.002], "v": [3.14, 2.71] },
+    "Counter":  { "t": [1747123456.001, 1747123456.002], "v": [12340, 12341] },
+    "Ch1":      { "t": [1747123456.000, 1747123456.0001, ...], "v": [0.12, 0.13, ...] }
+  }
+}
+```
+
+- `t` — Unix timestamp in seconds (float64) for each sample.
+- `v` — physical value (after dequantization if applicable).
+- For **temporal arrays**, `t` and `v` have `N × batchSize` entries
+  (up to 2000 per 30 Hz tick after server-side decimation).
+- For **spatial arrays** the keys are `"Ch1[0]"`, `"Ch1[1]"`, etc.
+
+---
+
+## Reconnection Behaviour
+
+- **UDP reconnect:** The Go client reconnects to UDPStreamer automatically after 5 s
+  of silence. This handles MARTe2 restarts transparently.
+- **WebSocket keepalive:** The server sends a WebSocket ping every 30 s. The browser
+  auto-responds; if no pong is received within 10 s the connection is closed and the
+  browser reconnects with exponential backoff (starting at 1 s, capped at 30 s).
+- **Buffer preservation:** Browser-side signal buffers are only reset when the signal
+  layout changes (name, type, or dimensions differ). A reconnect with the same CONFIG
+  keeps existing data visible in the plots.

+
+| Component | Type | Description |
+|-----------|------|-------------|
+| [UDPStreamer](Docs/UDPStreamer.md) | DataSource | Streams MARTe2 signals to a single UDP client in real time |
+| [SineArrayGAM](Docs/SineArrayGAM.md) | GAM | Generates continuous sinusoidal burst arrays (testing / demo) |
+
+## Client Tools
+
+| Tool | Description |
+|------|-------------|
+| [WebUI](Docs/WebUI.md) | Browser-based real-time plotter — connects to UDPStreamer via UDP, exposes data over WebSocket |
+
+## Quick Start
+
+```bash
+# 1. Configure environment (edit paths to point at your MARTe2 builds)
+source marte_env.sh
+
+# 2. Build everything and run the demo application with the browser UI
+cd Test/MARTeApp
+./run.sh --webui
+
+# 3. Open http://localhost:8080 in a browser
+#    Drag signals from the sidebar onto a plot panel to visualise them.
+```
+
+See the [Tutorial](Docs/Tutorial.md) for a step-by-step walkthrough.
+
+## Building
+
+### UDPStreamer library
+
+```bash
+source marte_env.sh
+make -f Makefile.gcc TARGET=x86-linux
+```
+
+### Unit tests
+
+```bash
+source marte_env.sh
+make -f Makefile.gcc TARGET=x86-linux test
+./Build/x86-linux/Tests/GTest/MainGTest.ex --gtest_filter="UDPStreamer*"
+```
+
+### WebUI client
+
+```bash
+cd Client/WebUI
+go build -o udpstreamer-webui ./...
+```
+
+## Repository Layout

+ *
+ * The sampleOffset accumulates across calls so the waveform phase is continuous.
+ *
+ * Configuration:
+ * <pre>
+ * +MyGAM = {
+ *     Class = SineArrayGAM
+ *     Frequency    = 1000.0       // Signal frequency in Hz (default 1.0)
+ *     Amplitude    = 1.0          // Signal amplitude (default 1.0)
+ *     Offset       = 0.0          // DC offset (default 0.0)
+ *     Phase        = 0.0          // Phase in radians (default 0.0)
+ *     SamplingRate = 1000000.0    // Sample rate in Hz; must match UDPStreamer signal (default 1000000.0)
+ *     OutputSignals = {
+ *         Ch1 = { DataSource = DDB; Type = float32; NumberOfElements = 1000 }
+ *     }
+ * }
+ * </pre>
+ *
+ * Exactly one output signal of type float32 is required.

+/**
+ * @brief A DataSource that streams MARTe2 signals to a single UDP client.
+ *
+ * @details This output DataSource accepts signals from GAMs and forwards them
+ * asynchronously to a connected UDP client. A dedicated background thread handles
+ * all network I/O so that the real-time thread is only blocked for a fast spinlock
+ * and a memcpy during Synchronise().
+ *
+ * Protocol:
+ * - Client sends CONNECT → server replies with CONFIG describing all signals.
+ * - Server sends DATA packets (fragmented if needed) on every RT cycle.
+ * - Client sends ACK packets (optional, for monitoring loss).
+ * - Client sends DISCONNECT to terminate the session.
+ *
+ * Signal configuration syntax:
+ * <pre>

+ *
+ * Notes:
+ *  - QuantizedType is only valid for float32/float64 signals.
+ *  - TimeMode = PacketTime uses the HRT counter captured in Synchronise().
+ *  - TimeMode = FullArray requires TimeSignal to have the same NumberOfElements.
+ *  - TimeMode = FirstSample/LastSample requires a scalar TimeSignal and SamplingRate.

+/**
+ * Test MARTe2 application for UDPStreamer DataSource.
+ *
+ * Generates scalar and high-frequency packed signals and streams them via UDPStreamer.
+ * Connect with the WebUI client (Client/WebUI) to visualise the signals.
+ *
+ * Signals produced (scalar, 10 kHz):
+ *   Counter  – uint32 cycle counter from LinuxTimer
+ *   Time     – uint32 time in microseconds from LinuxTimer
+ *   Sine1    – float32, 1 Hz sine, amplitude 10, quantised to uint16 on wire
+ *   Sine2    – float32, 0.3 Hz sine, amplitude 5, raw float32 on wire
+ *
+ * Signals produced (packed temporal arrays, 10 kHz × 1000 samples = 10 MSps):
+ *   Ch1      – float32[1000], 1 kHz sine, amplitude 1.0
+ *   Ch2      – float32[1000], 1 kHz sine, amplitude 0.5, phase π/2
+ *   Both channels use TimeMode=FirstSample with Time as the anchor and
+ *   SamplingRate=10000000 so the WebUI reconstructs the per-sample timestamps.
