# AGENTS.md - Sirens Project
|
||||||
|
|
||||||
|
## Project Overview
|
||||||
|
|
||||||
|
This is an Arduino/ESP32 embedded systems project for controlling sirens. The codebase consists of multiple Arduino sketches (.ino files) for different hardware components.
|
||||||
|

## Build Commands
|
||||||
|
|
||||||
|
### Current State
|
||||||
|
- **No command-line build system configured** - Uses Arduino IDE
|
||||||
|
- Upload via Arduino IDE or PlatformIO (recommended for future)
|
||||||
|
|
||||||
|
### Future: PlatformIO Migration (TODO)
|
||||||
|
```bash
|
||||||
|
# Once PlatformIO is configured:
|
||||||
|
pio run # Build all projects
|
||||||
|
pio run -e <environment> # Build specific environment
|
||||||
|
pio run -t upload # Upload to device
|
||||||
|
pio device monitor # Monitor serial output
|
||||||
|
```
|
||||||
|
|
||||||
|
### Running a Single Test
|
||||||
|
- **No unit tests exist** - Embedded projects typically test via hardware
|
||||||
|
- For now, manual testing on physical hardware is required
|
||||||
|
|
||||||
|
## Libraries
|
||||||
|
|
||||||
|
The project uses the following Arduino/ESP32 libraries:

## Code Style Guidelines
|
||||||
|
|
||||||
|
### General Conventions
|
||||||
|
|
||||||
|
- **Language**: C++ (Arduino framework)
|
||||||
|
- **File extension**: `.ino` (Arduino sketch)
|
||||||
|
- **Naming**: camelCase for variables and functions
|
||||||
|
- **Constants**: UPPER_SNAKE_CASE with `const` or `#define`
|
||||||
|
|
||||||
|
### Arduino Sketch Structure
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// 1. Includes
|
||||||
|
#include "WiFi.h"
|
||||||
|
#include <Wire.h>
|
||||||
|
#include <SSD1306Ascii.h>
|
||||||
|
|
||||||
|
// 2. Global constants
|
||||||
|
const int sirenCount = 4;
|
||||||
|
const char* ssid = "sirening";
|
||||||
|
|
||||||
|
// 3. Global variables
|
||||||
|
int menuSelect = 0;
|
||||||
|
|
||||||
|
// 4. Function prototypes (if needed)
|
||||||
|
void setupEncoderButton(AiEsp32RotaryEncoder& eb, char* val);
|
||||||
|
|
||||||
|
// 5. setup() - runs once at boot
|
||||||
|
void setup() {
|
||||||
|
Serial.begin(115200);
|
||||||
|
// initialization code...
|
||||||
|
}
|
||||||
|
|
||||||
|
// 6. loop() - runs continuously
|
||||||
|
void loop() {
|
||||||
|
// main logic...
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Functions
|
||||||
|
|
||||||
|
- Keep functions focused and reasonably sized (<100 lines)
|
||||||
|
- Use descriptive names: `updateFreq()`, `killAll()`, `setupOSC()`
|
||||||
|
- Group related functions together
|
||||||
|
- Use helper functions to reduce duplication in loop()
|
||||||
|
|
||||||
|
### Types
|
||||||
|
|
||||||
|
- Use explicit types: `int`, `float`, `bool`, `unsigned long`
|
||||||
|
- Prefer `const` for values that won't change
|
||||||
|
- Use `float` for floating-point values (no `double` on ESP32)
|
||||||
|
|
||||||
|
### Error Handling
|
||||||
|
|
||||||
|
- Return early on errors:
|
||||||
|
```cpp
|
||||||
|
if(!currentSense.init()){
|
||||||
|
Serial.println("Current sense init failed.");
|
||||||
|
return;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
- Use Serial for debugging output with descriptive messages
|
||||||
|
- Validate input ranges before use:
|
||||||
|
```cpp
|
||||||
|
if (input < 500.0 && input >= 0.0) {
|
||||||
|
updateFreq(input);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Interrupt Service Routines (ISR)
|
||||||
|
|
||||||
|
- Mark ISRs with `IRAM_ATTR` on ESP32:
|
||||||
|
```cpp
|
||||||
|
void IRAM_ATTR readFreqEncoderISR() {
|
||||||
|
encoderButton1.readEncoder_ISR();
|
||||||
|
}
|
||||||
|
```
|
||||||
|
- Keep ISRs minimal - only do essential work
|
||||||
|
|
||||||
|
### Display/UI Code
|
||||||
|
|
||||||
|
- Use helper functions for display updates:
|
||||||
|
```cpp
|
||||||
|
void updateDisplayValue(String string) {
|
||||||
|
oled.set2X();
|
||||||
|
oled.setCursor(12, 5);
|
||||||
|
oled.print(string);
|
||||||
|
oled.clearToEOL();
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### OSC Communication
|
||||||
|
|
||||||
|
- Use lambda callbacks for OSC subscriptions:
|
||||||
|
```cpp
|
||||||
|
OscWiFi.subscribe(settings_port, "/freq", [](const OscMessage& m) {
|
||||||
|
float input = m.arg<float>(0);
|
||||||
|
// handle message...
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Preferences (NVS)
|
||||||
|
|
||||||
|
- Open with explicit mode:
|
||||||
|
```cpp
|
||||||
|
prefs.begin("prefs", RO_MODE); // false = read/write, true = read only
|
||||||
|
prefs.putUInt("ports", ports);
|
||||||
|
prefs.getUInt("ports");
|
||||||
|
prefs.end();
|
||||||
|
```
|
||||||
|
|
||||||
|
### Serial Communication
|
||||||
|
|
||||||
|
- Use `Serial.begin(115200)` for debug output
|
||||||
|
- Use `HardwareSerial` for additional UARTs:
|
||||||
|
```cpp
|
||||||
|
HardwareSerial freqSerial(1);
|
||||||
|
freqSerial.begin(115200, SERIAL_8N1, 18, 19);
|
||||||
|
```
|
||||||
|
|
||||||
|
### Comments
|
||||||
|
|
||||||
|
- Use TODO comments for future work:
|
||||||
|
```cpp
|
||||||
|
//TODO: These should be bound to a publication of the frequency directly from the siren
|
||||||
|
```
|
||||||
|
- Comment out disabled code with explanation
|
||||||
|
- Keep comments brief and purposeful
|
||||||
|
|
||||||
|
### Formatting
|
||||||
|
|
||||||
|
- Use 2-space indentation (Arduino default)
|
||||||
|
- Opening brace on same line
|
||||||
|
- Space after keywords: `if (` not `if(`
|
||||||
|
|
||||||
|
## Future Improvements
|
||||||
|
|
||||||
|
1. **Add PlatformIO**: Create `platformio.ini` for command-line builds
|
||||||
|
2. **Add unit tests**: Use PlatformIO unit testing for non-hardware logic
|
||||||
|
3. **Consolidate common code**: Extract shared utilities into a common library
|
||||||
|
4. **Add CI/CD**: GitHub Actions for build verification
|
||||||
|
5. **Document hardware**: Add wiring diagrams and pinouts
|
||||||
|
|
||||||
|
## Hardware Targets
|
||||||
|
|
||||||
|
- **ESP32** (WiFi + BLE)
|
||||||
|
- **B-G431B-ESC1** motor controller (SimpleFOC compatible)

# Tunable Sirens
|
||||||
|
|
||||||
|
A programmable, tunable siren system using BLDC motors with FOC (Field-Oriented Control).
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This project implements a tunable siren where the frequency is controlled remotely via OSC (Open Sound Control) messages over WiFi. The system uses a DJI 2212 920KV BLDC motor driven by a B-G431B-ESC1 controller running SimpleFOC. Multiple stations can be controlled independently or simultaneously.
|
||||||
|
|
||||||
|

||||||
|
## Communication Modes
|
||||||
|
|
||||||
|
### 1. Via Remote Control (Router Mode)
|
||||||
|
|
||||||
|
The remote control acts as a WiFi access point and forwards OSC messages to stations. This allows controlling multiple sirens from a single entry point.
|
||||||
|
|
||||||
|
- **Remote IP**: `192.168.4.200`
|
||||||
|
- **Port**: `54001` (receives commands)
|
||||||
|
|
||||||
|
### 2. Direct to Station
|
||||||
|
|
||||||
|
Send OSC messages directly to each station's IP address:
|
||||||
|
|
||||||
|
- **Station 1**: `192.168.4.201:54000`
|
||||||
|
- **Station 2**: `192.168.4.202:54000`
|
||||||
|
- And so on...
|
||||||
|
|
||||||
|
### WiFi Setup
|
||||||
|
|
||||||
|
- **SSID**: `sirening`
|
||||||
|
- **Password**: `alarm_11735`
|
||||||
|
- **IP Range**: `192.168.4.200` (remote) + `201-208` (stations)
|
||||||
|
|
||||||
|
## OSC Protocol
|
||||||
|
|
||||||
|
### Messages
|
||||||
|
|
||||||
|
| Address | Arguments | Description |
|
||||||
|
|---------|-----------|-------------|
|
||||||
|
| `/freq` | `motorIndex, frequency` | Set frequency in Hz (0-500) |
|
||||||
|
| `/kill` | — | Stop siren (set frequency to 0) |
|
||||||
|
| `/state` | `motorIndex, frequency` | Station reports current state |
|
||||||
|
|
||||||
|
### Example (Python)
|
||||||
|
|
||||||
|
```python
|
||||||
|
from pythonosc import osc_message_builder
|
||||||
|
from pythonosc.udp_client import SimpleUDPClient
|
||||||
|
|
||||||
|
client = SimpleUDPClient("192.168.4.201", 54000)
|
||||||
|
|
||||||
|
# Set frequency to 100Hz for motor 1
|
||||||
|
msg = osc_message_builder.OscMessageBuilder(address="/freq")
|
||||||
|
msg.add_arg(1) # motorIndex (1-indexed)
|
||||||
|
msg.add_arg(100.0) # frequency in Hz
|
||||||
|
client.send(msg.build())
|
||||||
|
|
||||||
|
# Kill/stop the siren
|
||||||
|
msg = osc_message_builder.OscMessageBuilder(address="/kill")
|
||||||
|
client.send(msg.build())
|
||||||
|
```
|
||||||
|
|
||||||
|
### Station Response
|
||||||
|
|
||||||
|
The station reports its state back on port `54001`:
|
||||||
|
|
||||||
|
```python
|
||||||
|
# Incoming message: /state motorIndex frequency
|
||||||
|
# Example: /state 1 100.0
|
||||||
|
```
|
||||||
|
|
||||||
|
## Local Controls
|
||||||
|
|
||||||
|
Both the remote control and station controllers have a local interface:
|
||||||
|
|
||||||
|
### Rotary Encoder
|
||||||
|
|
||||||
|
| Action | Function |
|
||||||
|
|--------|----------|
|
||||||
|
| Rotate | Change frequency (or navigate menus) |
|
||||||
|
| Press | Select siren / confirm selection |
|
||||||
|
| Double-press (remote) | Kill all sirens |
|
||||||
|
|
||||||
|
### OLED Display
|
||||||
|
|
||||||
|
- Shows current frequency
|
||||||
|
- Shows selected siren number
|
||||||
|
- Shows connection status (WiFi)
|
||||||
|
|
||||||
