Timer1 for motor control (20kHz)

Timer1_Center Aligned mode1 (up counting)

In Mode 1, the timer counter starts from zero and increments until it reaches the auto-reload value (ARR). When the counter matches the compare value (CCR), the output state is toggled.

Fclk = 170MHz

Fpwm = 20kHz

ARR+1 = 4250

 

Generate a 20kHz switching frequency using TIM1 center-aligned mode. For center-aligned mode, the actual PWM frequency is
