Nucleo F411re, High frequency PWM
Hi. I'm using current sensor for measuring torque of DC motor(current->voltage->ADC). But my current sensor has 10khz bandwidth. (When PWM signal changing high and low, it is reflected in sensor voltage). Because of this problem, I want to make very high frequency (over 20khz) PWM signal. Can I get some code example?
Thank you for reading and really sorry about my terrible English.

20 kHz is a period of 50 us.
The handbook for PWM is here and it shows you can use:
pwm.period_us (50)
