# LED Driver — MicroPython
# Portal panel firmware (Pico + W5500 + WS2812)
MicroPython LED driver for ESP32: presets, patterns, **Wi-Fi** (TCP + UDP discovery) or **ESP-NOW** transport, optional HTTP polling, and dynamic pattern modules under `src/patterns/`.
UDP RGB panel adapter for the [portal](https://git.technical.kiwi/technicalkiwi/portal.git) project.
Host renders patterns; this firmware only receives frames on **UDP 50007**.
## Prerequisites
## Layout
- MicroPython firmware on the ESP32
- USB cable for programming
- Python 3 with pipenv (on the host, for `dev.py` / tests)
```text
led-driver-8/
├── firmware/ # Pico SDK C + W5500
├── examples/test_strips.py
├── .env.example
└── README.md
```
## Setup
## Hardware
1. Install dependencies:
| Signal | GPIO |
|--------|------|
| W5500 CS | GP13 |
| SPI1 SCK | GP10 |
| SPI1 MOSI | GP11 |
| SPI1 MISO | GP12 |
| W5500 RST | GP9 |
| Status LED | GP25 |
| WS2812 strip 07 | GP18, 19, 20, 21, 22, 26, 27, 28 |
Eight strips (one PIO SM each). Pixel output uses **DMA → PIO**. Pixel count comes from each UDP frame. `MAX_LEDS` (512) is capacity only.
## Build / flash
```bash
pipenv install
cd firmware
make deploy PANEL_ID=0
make reset && make monitor
```
2. Deploy to the device:
Network options live in `.env` (see `.env.example`):
```env
PANEL_ID=0
NETWORK=static
IP=10.1.1.10
NETMASK=255.255.255.0
GATEWAY=10.1.1.1
DNS=10.1.1.1
```
| Panel | IP | MAC last byte |
|-------|-----|---------------|
| 0 | 10.1.1.10 | `00` |
| … | … | … |
| 4 | 10.1.1.14 | `04` |
| 255 (bench) | 10.1.1.19 | `FF` |
## Test
Self-contained (stdlib only):
```bash
pipenv run dev
python3 examples/test_strips.py
python3 examples/test_strips.py --host 10.1.1.10 --leds 64
```
## Project layout
Lights each strip alone with a unique colour, then flashes all strips R/G/B/white.

## UDP protocol (port 50007)
**Transport:** `settings.json` **`transport_type`** is typically **`wifi`** (TCP to the Pi on port **8765**, discovery on **8766**) or **`espnow`**. ESP-NOW code paths are loaded only when needed so a Wi-Fi-only image stays smaller.
## Further reading
- **`docs/API.md`** — JSON message fields as used in examples (`pattern`, `colors`, …). The Pi app may send **short keys** (`p`, `c`, …); behaviour matches once normalised on device.
| Payload | Action |
|---------|--------|
| N×3 bytes | Raw RGB → strip 0 |
| 1 + N×3 bytes | `strip_id` + RGB (`0``7`, or `255` = all) |
| 5 bytes `PIN\0` + gpio | Bind strip 0 |
| 8 bytes `PIN\0` + strip + gpio + len_lo + len_hi | Bind strip |
| 4 bytes `SHOW` | Reserved |

# LED Driver API (message format)
This document describes the **JSON message format** for controlling LED driver devices. The same object is accepted from **ESP-NOW** (when that transport is enabled) and as **one JSON value per line** over **TCP** in **Wi-Fi** mode (see `src/main.py` on the device).
## Message Format
All messages are JSON objects with the following structure:
```json
{
"v": "1",
"presets": { ... },
"select": { ... }
}
```
### Version Field
- **`v`** (required): Message version, must be `"1"`. Messages with other versions are ignored.
## Presets
Presets define LED patterns with their configuration. Each preset has a name and contains pattern-specific settings.
### Preset Structure
```json
{
"presets": {
"preset_name": {
"pattern": "pattern_type",
"colors": ["#RRGGBB", ...],
"delay": 100,
"brightness": 127,
"auto": true,
"n1": 0,
"n2": 0,
"n3": 0,
"n4": 0,
"n5": 0,
"n6": 0
}
}
}
```
### Preset Fields
- **`pattern`** (required): Pattern type. Options:
- `"off"` - Turn off all LEDs
- `"on"` - Solid colour
- `"blink"` - Blinking pattern
- `"rainbow"` - Rainbow colour cycle
- `"pulse"` - Pulse/fade pattern
- `"transition"` - Colour transition
- `"chase"` - Chasing pattern
- `"circle"` - Circle loading pattern
- **`colors`** (optional): Array of hex colour strings (e.g., `"#FF0000"` for red). Default: `["#FFFFFF"]`
- Colours are automatically converted from hex to RGB and reordered based on device colour order setting
- Supports multiple colours for patterns that use them
- **`delay`** (optional): Delay in milliseconds between pattern updates. Default: `100`
- **`brightness`** (optional): Brightness level (0-255). Default: `127`
- **`auto`** (optional): Auto mode flag. Default: `true`
- `true`: Pattern runs continuously
- `false`: Pattern advances one step per beat (manual mode)
- **`n1` through `n6`** (optional): Pattern-specific numeric parameters. Default: `0`
- See pattern-specific documentation below
### Pattern-Specific Parameters
#### Rainbow
- **`n1`**: Step increment (how many colour wheel positions to advance per update). Default: `1`
#### Pulse
- **`n1`**: Attack time in milliseconds (fade in)
- **`n2`**: Hold time in milliseconds (full brightness)
- **`n3`**: Decay time in milliseconds (fade out)
- **`delay`**: Delay time in milliseconds (off between pulses)
#### Transition
- **`delay`**: Transition duration in milliseconds
#### Chase
- **`n1`**: Number of LEDs with first colour
- **`n2`**: Number of LEDs with second colour
- **`n3`**: Movement amount on even steps (can be negative)
- **`n4`**: Movement amount on odd steps (can be negative)
#### Circle
- **`n1`**: Head movement rate (LEDs per second)
- **`n2`**: Maximum length
- **`n3`**: Tail movement rate (LEDs per second)
- **`n4`**: Minimum length
## Select Messages
Select messages control which preset is active on which device. The format uses a list to support step synchronization.
### Select Format
```json
{
"select": {
"device_name": ["preset_name"],
"device_name2": ["preset_name2", step_value]
}
}
```
### Select Fields
- **`select`**: Object mapping device names to selection lists
- **Key**: Device name (as configured in device settings)
- **Value**: List with one or two elements:
- `["preset_name"]` - Select preset (uses default step behavior)
- `["preset_name", step]` - Select preset with explicit step value (for synchronization)
### Step Synchronization
The step value allows precise synchronization across multiple devices:
- **Without step**: `["preset_name"]`
- If switching to different preset: step resets to 0
- If selecting "off" pattern: step resets to 0
- If selecting same preset (beat): step is preserved, pattern restarts
- **With step**: `["preset_name", 10]`
- Explicitly sets step to the specified value
- Useful for synchronizing multiple devices to the same step
### Beat Functionality
Calling `select()` again with the same preset name acts as a "beat" - it restarts the pattern generator:
- **Single-tick patterns** (rainbow, chase in manual mode): Advance one step per beat
- **Multi-tick patterns** (pulse in manual mode): Run through full cycle per beat
Example beat sequence:
```json
// Beat 1
{"select": {"device1": ["rainbow_preset"]}}
// Beat 2 (same preset = beat)
{"select": {"device1": ["rainbow_preset"]}}
// Beat 3
{"select": {"device1": ["rainbow_preset"]}}
```
## Synchronization
### Using "off" Pattern
Selecting the "off" pattern resets the step counter to 0, providing a synchronization point:
```json
{
"select": {
"device1": ["off"],
"device2": ["off"]
}
}
```
After all devices are "off", switching to a pattern ensures they all start from step 0:
```json
{
"select": {
"device1": ["rainbow_preset"],
"device2": ["rainbow_preset"]
}
}
```
### Using Step Parameter
For precise synchronization, use the step parameter:
```json
{
"select": {
"device1": ["rainbow_preset", 10],
"device2": ["rainbow_preset", 10],
"device3": ["rainbow_preset", 10]
}
}
```
All devices will start at step 10 and advance together on subsequent beats.
## Complete Example
```json
{
"v": "1",
"presets": {
"red_blink": {
"pattern": "blink",
"colors": ["#FF0000"],
"delay": 200,
"brightness": 255,
"auto": true
},
"rainbow_manual": {
"pattern": "rainbow",
"delay": 100,
"n1": 2,
"auto": false
},
"pulse_slow": {
"pattern": "pulse",
"colors": ["#00FF00"],
"delay": 500,
"n1": 1000,
"n2": 500,
"n3": 1000,
"auto": false
}
},
"select": {
"device1": ["red_blink"],
"device2": ["rainbow_manual", 0],
"device3": ["pulse_slow"]
}
}
```
## Message Processing
1. **Version Check**: Messages with `v != "1"` are rejected
2. **Preset Processing**: Presets are created or updated (upsert behavior)
3. **Colour Conversion**: Hex colours are converted to RGB tuples and reordered based on device colour order
4. **Selection**: Devices select their assigned preset, optionally with step value
## Best Practices
1. **Always include version**: Set `"v": "1"` in all messages
2. **Use "off" for sync**: Select "off" pattern to synchronize devices before starting patterns
3. **Beats for manual mode**: Send select messages repeatedly with same preset name to advance manual patterns
4. **Step for precision**: Use step parameter when exact synchronization is required
5. **Colour format**: Always use hex strings (`"#RRGGBB"`), conversion is automatic
## Error Handling
- Invalid version: Message is ignored
- Missing preset: Selection fails, device keeps current preset
- Invalid pattern: Selection fails, device keeps current preset
- Missing colours: Pattern uses default white colour
- Invalid step: Step value is used as-is (may cause unexpected behavior)
## Notes
- Colours are automatically converted from hex strings to RGB tuples
- Colour order reordering happens automatically based on device settings
- Step counter wraps around (0-255 for rainbow, unbounded for others)
- Manual mode patterns stop after one step/cycle, waiting for next beat
- Auto mode patterns run continuously until changed

# Pattern Contract (Important)
Pattern classes are loaded dynamically by `Presets._load_dynamic_patterns()`.
Patterns must follow this contract exactly.
## Required class shape
- File name is the pattern id (for example `blink.py` -> pattern name `blink`).
- Module exports a class with:
- `__init__(self, driver)` where `driver` is the `Presets` instance.
- `run(self, preset)` that returns a generator.
`Presets` binds patterns like this:
- `pattern_class(self).run`
- then calls `self.patterns[preset.p](preset)` and stores that generator.
- every frame, `Presets.tick()` does `next(self.generator)`.
## `run()` generator rules
- `run()` must `yield` frequently (normally once per tick loop).
- Do not block inside `run()`:
- no `sleep()` / `sleep_ms()` / long loops without `yield`.
- no network or file I/O.
- Use time checks (`utime.ticks_ms()` + `utime.ticks_diff(...)`) to schedule updates.
- Keep pattern state inside local variables in `run()` (or object fields if needed).
## Drawing and brightness
- Use `self.driver.apply_brightness(color, preset.b)` for per-preset brightness.
- Write pixels through `self.driver.n[...]` / `self.driver.n.fill(...)`.
- Flush frame with `self.driver.n.write()`.
- If a pattern needs to clear, use black `(0, 0, 0)`.
## Step semantics
- `self.driver.step` is shared pattern state managed by `Presets.select(...)` and patterns.
- Patterns that use step-based progression should update `self.driver.step` themselves.
- `select(..., step=...)` may set an explicit starting step.
## Error handling
- Let unexpected errors raise inside the generator.
- `Presets.tick()` catches exceptions, logs, and stops the active generator.
- Pattern code should not swallow broad exceptions unless there is a clear recovery path.
## Built-ins
- `off` and `on` are built-in methods on `Presets`, not loaded from this folder.
- `__init__.py` is ignored by dynamic loader.

"""mDNS smoke test — runs on the MicroPython device (ESP32).
Loads Wi-Fi credentials from /settings.json via Settings (same as main firmware).
Sets the network hostname before connect so the chip can advertise as <hostname>.local
on builds where mDNS is enabled (see network.hostname() in MicroPython docs).
By default the script stays connected until you stop it (reset or mpremote Ctrl+C) so you
can ping the mDNS name from another machine (e.g. name "a" -> leda.local; hyphens are omitted
in the hostname because ESP32 mDNS often breaks on '-').
After flashing, do a full hardware reset once so the first DHCP sees the new hostname.
Deploy src to the device (including utils.py with mdns_hostname), then from the host:
mpremote connect PORT run tests/test_mdns.py
Copy ``utils.py`` from ``src/`` onto the device if imports fail.
Or with cwd led-driver:
mpremote connect /dev/ttyUSB0 run tests/test_mdns.py
