I started this project as a way to start developing with the STM32 line
of ARM microcontrollers, as most of my previous experience has been with
AVRs. My goal is to create a very small PID controller with onboard
display and USB on a single-side-populated PCB so they can be
Currently I have all of the peripherals (except USB) up and running and my code is partially complete. Over time I will post more information about what I've already done and problems that I have solved. The source code will be made open-source once I'm a little further along.
