Resolved! Triggering ADC with Timer1 and Rpetition Counter

Hi There,I am currently working on ADC and Timer. I have 3 channels of ADC and using DMA. I want to trigger ADC at Timer1's update event. Also, I've set Timer's parameters to center aligned pwm, repetition counter to 1(with this I will trigger ADC at...

Why the number of pulses is less than expected when I am using One Pulse Mode and Repetition Counter (RCR) to generate adjustable PWM pulses with number and frequency?

I need to generate PWM signals with adjustable number and frequency to drive a step motor. I expect the frequency ranges from 50Hz to 200KHz and the pulses count ranges from 1 to 2k. I have tried 3 different ways including: using timer interrupt to c...
