This repository is a part of a larger project. The description of it can be found in the rotary-head-software repository.
This repository contains the firmware for the STM8L101K3T microcontroller, which is placed on the PCB of the Rotary Head Controller. The firmware is written in C and depends on the IAR Embedded Workbench library for STM8.
The binary can be built using the IAR Embedded Workbench for STM8. There is a SWIM interface exposed on the pin header of the mentioned PCB, which allows uploading the firmware using an ordinary programmer.
