Hi everyone, I meet a problem and I'm not sure it's MCU issue or I program not proper.I meet this issue both on the STM8 and STM32 MCUs.I enable TIM_2 Ch1 as input to capture the signal and TIM_2 Ch2 as output to do the compare function. void init_TI...

@waclawek.jan It really helps me a lot. I thought what I set is only 1 bit not a whole bits of register. But I trace the assembly code and it really did the LDR->BIC->STR and it cause the other interrupt flags clear either.Many thanks.

@waclawek.jan I handle the capture in the background.void get_capture_val(void) { if (TIM2.SR.bit.CC1IF == 1) { // .. // Handle the capture value // .. TIM2.SR.bit.CC1IF = 0; } }

@Issamos The timer compare ISR triggered is worked, but not worked everytime. That's why I record the timer register value in background but not using break point. Also the break point would pause the program and the ISR cannot stop in my design eve...

Hi Issamos,Thanks for your reply.I checked my interrupt config and the priority I set whatever it's high or low the symptom is the same.What I do to debug this issue is to record the timer compare value(CCR) and timer counter value(CNT) as I mentione...
