# Pico Ringer

This is a simple MicroPython project to forward a Ring chime from my [HomeNode](https://prasha.au/project/homenode) automation system to speakers.

A Pi Pico W listens for MQTT messages and uses a PCM5102A DAC to play the sound via a 3.5mm output.

## Setup development environment

### Python venv

1. Install `python3`

2. Create a virtualenv using `python -m venv .venv`

3. Activate the virtualenv using `source .venv/bin/activate` or `.venv/Scripts/activate.ps1`

4. Install the requirements using `pip install -r requirements.txt`

### Flash Micropython

You can grab the MicroPython firmware for a Pi Pico W from [this page](https://micropython.org/download/RPI_PICO_W/).

Drag/drop as per usual.

### Config file

Create a config file for credentials in `src/config.json`...

```json

{ "wifi_ssid": "", "wifi_psk": "", "mqtt_server": "192.168.1.4"}

```

### Setup Files

- Install libs using `mip.install('')`

- Copy over the audio file

- Copy config.json and helper files

## Developing

The easiest way to develop is to use `mpremote` to mount the src folder.

To begin clear out the `main.py` file and reboot. This allows you to use other commands without interference.

```python

import os

os.remove('main.py')

```

You can then mount the src folder...

```bash

mpremote mount src

```

From REPL you can start executing code. To "hot reload" a file you can run the following command.

This will let you import updated code.

```python

from utils import clear_mod

clear_mod(ringer)

```
