I'm struggling to find a solution to this by searching.I have an existing system running using PA1 as an EXTI set up through Cube MX. I just need to add an exrernal interrupt to PA0As far as I can see the following code is all I should need to add...

I'm working with CubeIDE and Blue Pill boards.I need to frequency count an external intermittant signal at about 4MHz. To do this I need to catch the start of the signal and do my 1ms count period as quickly as possible.I can't see a way to do this ...

I'm working in STM32 CubeIDE with a Blue Pill board.To control the size of main.c I have gathered groups of functions together in to several c/h pair files. One of the pairs is 'myirqcallbacks.c/h". At the moment I have two UART IRQs and an external ...

Help to add EXTI to a port already in use as ETR input for counter/timer (PA0). CubeIDE on STM31F103Thanks to waclawek.jan and TDK for your help with this.The crucial bits of code that worked for me are here. // Initialise Ext IRQ on PA0 (which is ...

Thanks for that. As far as I can see it is not possible to just add an EXTI to an existing input using MX. In this case the pin is already used as ETR for a counter timer. If I use MX I think it will force the pin to be a simple input/rising edg...

Thanks Jan. I don't know what SYSCFG is. There doesn't seem to be a file of that name in my project...

Thanks for that. I see that I am missing the EXTI0_IRQHandler. Should I create this function in stm32f1xx_it.c/h files next to its brother EXTI1_IRQHandler which was generated by MX, or should I put it in main.c or similar? I worry that it may be ...

berendi spotted the error in the function names for which thank you. Sadly this didn't solve the problem, I must have generated this one in my flapping about trying to solve the main problem.What fixed it in the end was regenerating the code from the...

Help to add EXTI to a port already in use as ETR input for counter/timer (PA0).

Can I use a pin as both ETR for a counter/timer and EXTI for same signal?
