Good evening everyone,At the moment I am trying to configure an inpute compare pin. Eventually we are going to calculate the frequency of the input signal etc etc, but for now we need to get the pin working.GPIOA->MODER = (GPIOA->MODER & ~GPIO_MODER_...

Currently I am trying to configure a second interrupt pin using CMSIS.SYSCFG->EXTICR[1] = (SYSCFG->EXTICR[1] & ~SYSCFG_EXTICR2_EXTI6)|(0b0000 << SYSCFG_EXTICR2_EXTI6_Pos); EXTI->FTSR = EXTI_FTSR_TR6; EXTI->RTSR = EXTI_RTSR_TR6; EXTI->IMR = EXTI_IMR_M...

Thanks for your reply! We are using the Nucleo F303RE.do you enable GPIOA clock in RCC?We didn't so we added it, still not workingyou don't set the AF for TIM2 in GPIO_AFR[] (btw. which STM32 are you using?)We indeed didn't and we added it, still not...

Didn't know how to disconnect SB14.I tried changing everything to PC01, still doesn't work.When I write a program to turn on / off a LED it works fine, so the pin itself is configured right.The problem lays in the configuration of the interrupt.

I think I can test the first one with a seperate program where I toggle a LED.Not so sure how to test the second question?

Yes, it is PA6 and PA3. Model is Nucleo F303RE. I guess it really is a software related issue..GPIOA->MODER = (GPIOA->MODER & ~GPIO_MODER_MODER3)|(0b00 << GPIO_MODER_MODER3_Pos); GPIOA->PUPDR = (GPIOA->PUPDR & ~GPIO_PUPDR_PUPDR3)|(0b10 << GPIO_PUPDR_...
