The working modes of the microcontroller I/O port are basically divided into the following categories:
1. Quasi-bidirectional IO port configuration (weak pull-up)

The two advanced timers TIM1 and TIM8 in the STM32 timer can generate 7 PWM waves because they have 7 pin channels respectively:
Channel 1
TIM1_CH1
PA8
Channel 1
TIM1_CH1N
...[Details]
For input signals of different channels, sometimes we hope that one channel signal satisfies one condition while another channel waveform satisfies another condition, that is, to realize the logica...[Details]
