Resolved! Direct Input Capture Interrupt too slow - STM32 L476RG
I'm trying to align an input 15 kHz signal with a 20% duty cycle with an output 15 kHz signal with a 50% duty cycle. To do this I'm hooking up the input signal to a direct capture interrupt and Timer 1 Channel 4 and using the HAL_TIM_IC_CaptureCallba...
Resolved! Accessing GPIOA CRL and CRH registers using STM32 HAL libraries
Hey,I was wondering how to interface GPIO port registers CRL and CRH with HAL libraries, as I don't see such an option and simple GPIOB->CRL line gives an error.Here are the available selections:
