hi, I found the frequency and the duty of the PWM can't be set correctly. eg, If you set the freq of the PWM to 20kHz, you will get a 19.9kHz wave form. if the freq is set to 10MHz, you will get a 9.1MHz wave form. And , if the freq is set to 10MHz, and set the duty to 50%, you will get a 55% duty.
