Enable/ disable EXTI interrupts using HAL

[AlexandrosAA]

Hey guys.

I need to enable/disable the line 14 of the EXTI interrupts multiple times, using HAL

Do i just use the HAL_NVIC_DisableIRQ  HAL_NVIC_EnableIRQ  ( and HAL_NVIC_SetPriority whenever i re-enable the line?), providing the correct handle to the api each time?

To enable/disable EXTI interrupts, you can set and clear raising/falling edge detection bit of the needed line in EXTI registers EXTI_RTSR1 and/or EXTI_FTSR1. Leave the NVIC interrupt enabled.  Not sure if the HAL library has a function for this. If not, do it without the HAL.

Hello @AlexandrosAA, 

You only need to set the priority once using HAL_NVIC_SetPriority unless you need to change the priority dynamically.

to enable the interrupt: HAL_NVIC_EnableIRQ(EXTI15_10_IRQn);

to disable the interrupt: HAL_NVIC_DisableIRQ(EXTI15_10_IRQn);
