Some confusion about the configuration of output compareHello, I am a beginner in STM32 MCUs. The MCU I am using is STM32F103ZET6.I'm trying to use the output compare function of the timer.But I came across something that confused me.I use STM32CubeM...

I apologize for the confusion my question caused you. But my question has always been very clear and that is, why the parameter pulse is not working as expected in output compare mode. I told you that I was testing the interrupt latency to show you w...

Thanks for the reply, but it doesn't solve my problem. I'm actually trying to test the interrupt latency of the ARM Cortex M3 chip using the output compare function, and I referenced this Application Note from NXP: https://www.nxp.com/docs/en/applica...

Because PWM mode compares the values of pulse and timer count, the level of the channel output of pwm is related to the relative size of their values. When I use pwm mode, the timer interrupt can only be generated when the value of timer count is gre...

Yeah, you're right. However, the problem I'm currently having is that it doesn't work no matter what my pulse parameter is set to. And the ARR parameter seems to do what the pulse parameter is supposed to do.As an example, whether my pulse parameter ...

Thanks for the reply, but the pwm model doesn't work for my needs. I need timer to output a level signal on the GPIO while generating an interrupt. It seems that only output compare mode can satisfy my needs.
