RIOT VS Openroast

RIOT-OS is somewhat popular in academia, it tries to be very approachable but there are still plenty of low hanging fruits with all kinds of hardware and you can use it for software and thesis projects.

Just one example: https://github.com/RIOT-OS/RIOT

You could also take a look at RIOT-OS. http://riot-os.org

RIOT-OS has a lot of unit tests for all the boards they support. And it's written in C. https://github.com/RIOT-OS/RIOT/tree/master/tests

Another option is using RIOT-OS. But that unfortunately doesn't support PWM for the Weact. It does support PWM for the Bluepill and Blackpill STM32f103 and the Nucleo-f446 After quick search. \ https://riot-os.org

If you want to use C, I would suggest trying out RIOT-OS. It's a modern embedded operating system, written in C and focussed on IOT. It works on a lot of different boards. https://github.com/RIOT-OS/RIOT

Alternatively, you can also write your code in an RTOS. They often have scripts that make flashing and debugging easy. One that I personally like, and also supports Arduino, is RIOT-OS.

You can use the manual controls on the panel or use the USB connections to control from your computer. I always create roasting profiles and use OpenRoast to automate the roasting process.

Coffee roasting : modified a hot air popcorn popper w/ a "solid state relay" to control the heat and used a max31855 thermocouple adc to get the temperature and python to control it (either https://github.com/Roastero/Openroast or https://artisan-scope.org) ...
