I'm trying to generate periodic interrupts with an LPTIM on an STM32H723. I'm using HAL_LPTIM_Counter_Start_IT() from the STM32H7xx_HAL_Driver. My interrupt handler is never being called. I've confirmed that my interrupt handler is in the vector tabl...

If I configure a pin as a timer input capture channel input, can I also read the state of that pin as a GPIO input?I'd like configure the timer channel as an input capture channel, and I'd like to capture both rising and falling edges. But when the e...

That was the piece I was missing. Once I did that, I get my interrupts as expected. Thanks!

P.S. I just figured out I can enable "Pin Stacking" for that pin in STMCubeMX to select both TIMx_CHy and GPIO_Input for that pin.FYI, after enabling "Pin Stacking" for that pin and clicking on GPIO_Input in the pop-up list of pin functions, it wipes...

Thanks! I got it working on my NUCLEO board.The only piece I was missing was that I have to call HAL_GPIO_ReadPin() using the generic port and pin definitions in the HAL GPIO header file [e.g. HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_0)] since STMCubeMX does...
