Re: how to PWM Frequency stm32duino and resolution
rather than waiting for someone to write the code for you, take a look at the reference manual and see how it can be done (easily as well).

Re: code crashing?, PC13 flashing? i2c
comment out certain sections of the code and see if you still have the problem.
and gradually narrow down the possible cause.

Re: software i2c?
you may want to consider switching the bus so that at a given point only one device is on the bus.
Much easier than having a gazillion i2c buses.

Measuring CPU usage
Wrote some routines to measure CPU usage. Basic concept is shown here, on a cortex-m0 chips: https://dannyelectronics.wordpress.com/2020/07/05/measuring-cpu-mcu-utilization-on-cortex-mx-chips/ it runs off of SysTick. Ported it over to Arduino here: https://dannyelectronics.wordpress.com/2020/07/06/m...

Re: dhrystone and whetstone benchmarks
my attempt, at benchmarking a variety of chips, and outside of the typical dhrystone / whetstone routines: https://dannyelectronics.wordpress.com/ ... -exercise/
Interesting to see how the chips fall. the numbers are measured in cycle counts.
