Piano Sensor Project

Electronic Design

This repo contains the following KiCad projects

encoder-breakout is the breakout pcb for the AEDR-8300 optical encoder IC
main-board is a daisychainable board that connects to five encoder-breakouts
uart-adapter connects to the main-board and computer (USB) and also delivers power.

There are two firmware projects

firmware was the first try. It works and decodes the encoder signals but does not have all functionality such as daisychaining.
firmware-rftm is firmware based on the cortex-m-rtfm framework. This has all functionality and is compatible with the python app.

The python app lives in a Pipenv virtual environment. First time you need to run the following command to install:

pipenv install

Then to run:

pipenv shell
python app.py
