The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
The frequency calculation formula of the PWM wave generated by the output comparison mode of the timer is: 72M/((2*(arr+1))*(psc+1) ) For example, if you set: PWM_Init(1000-1,72-1); (PWM_Init(arr,psc...[Details]
