-- firmware
+- Electronic design
+- Firmware written in Rust for stm32f103
+- Python app for data visualization
+
+
+## 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 delivers power. 
+
+
+## Firmware
+
+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`](https://rtfm.rs) framework. This has all functionality and is compatible with the python app.
+
+
+## App
+
+The python app lives in a Pipenv virtual environment. First time you need to run the following command to install:
+
+```bash
+pipenv install
+```
+
+Then to run:
+
+```
+pipenv shell
+python app.py
+```
