Generate pulses using two timers

I want to generate a ~200us pulse on the DAC (variable output) that occurs at 20Hz.The DAC itself is no problem, the 20Hz is done with a timer interrupt.What is the best way to implement the 200us timing? Preferably non-blocking, Another timer that s...

Distinguish different STM32G0 variants at run-time

Hi,Is it possible to distinguish an STM32G0B1KBU6N from an STM32G0B1KBU6 based on the UID?Is it possible to read this UID in FW in order to recognize whether the correct controller is fitted or is this only possible via the SW interface?

Resolved! How to test real ADC frequency and its accuracy?

Hi guys, I'd like to test if the true ADC frequency is the same as what I've set. The ADC setting is HSI14 (14 MHz) as clock source, 12 bits resolution (corresponds to 12.5 ADC clock cycles), sampling time is 1.5 clock cycles. Therefore, one conversi...
