# Pico AlertDisplay

A CircuitPython project to integrate a simple P5 LED Panel with my [Homenode](https://prasha.au/project/homenode) automation system.

A Pi Pico W listens for MQTT messages and shows:

- timers from Google Home

- the weather

- other various alerts from the system as icons

## Preview

## Initial setup

### Python venv

1. Install `python3`

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

3. Activate the virtualenv using `.\.venv\Scripts\Activate.ps1`

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

### CircuitPython Device Deps

```shell

circup install -r device-requirements.txt

```

## Developing

Using REPL is the best way to quickly test things. The [displaytest.py](./src/displaytest.py) file has rough code for quickly displaying things.

### REPL

```shell

// Windows

plink -serial \\.\COM5 -sercfg 115200,8,1,N,N

// OSX

screen /dev/cu.xxxxxxx

```

### Sample MQTT Invokes

```pip i

mqtt publish -t alertdisplay/setTimer -m pan,60

mqtt publish -t alertdisplay/removeTimer -m pan

mqtt publish -t alertdisplay/setIcon -m chicken,true

mqtt publish -t alertdisplay/setPower -m true

```

### Screen Item Layouts

```

I I W         // (x: (2, 22, 45), y: 1)

I I W         // (x: (2, 22, 45), y: 16)

### Creating Icons

You can use [Piskel](https://www.piskelapp.com/) and import the BMP files to edit them.

Piskel can export to PNG and you can use the command below (on OSX) to convert it to BMP.

```bash

sips -s format jpeg test.png --out test.jpg

```
