Arduino for STM32

I am not aware of the H7 Arduino library implementation. You should get 1 us resolution. If you need 5 nanosecond resolution (with 400 MHz clock) then you can use the following two macros


#define initCycleCounter() \
CoreDebug->DEMCR |= CoreDebug_DEMCR_TRCENA_Msk; \
DWT->CYCCNT = 0; \
DWT ...

I like STM32WB, but the price compared to RPi4 and ESP32 makes it unfeasible for most projects.

I like your efficient programming style. Efficient usage of resources, avoidance of the bloatware, and proper level of documentation and naming conventions are hall marks of long term experience. Well done

The STM32F103C has 16 EXTI lines that can be programmed to trigger interrupts from the GPIO pins. That is not the proper method in case there is no electronic RC filtering of the signals. In practice, it is very difficult to have the proper values for the RC filtering.

A better method is to use ...

I really like RobotDyn products and have been using them for several years. I was tempted to purchase the APM32F103CB board, but then realized that life is too short to fight against or run with the wind mills. Now, I have turned a new leaf in my MCU projects and will focus on the F411 and H750 ...

Thanks for sharing this. It is pretty and has all the relevant information.
