WebCH Polarity即通道输出极性。我们用TIM3向上计数模式, 按照前面PWM原理图解, CH Polarity的极性加上IO逻辑, 才是最终PWM的波形; 举个栗子, 如果CH Polarity为High(1), 那么当向上计数到CCRx之前本该是0(低电平), 但实际上还要加上Ch的输出极性, 所以那一段实际上是输出1(高电平)。 WebI don't CubeMX, but this sounds like: Reference Manual (I used RM0090 but I bet this is the same accross all STM32), Timer chapter: Particular case: OCx fast enable: In One-pulse mode, the edge detection on TIx input set the CEN bit which enables the . counter. Then the comparison between the counter and the compare value makes the . output toggle.
