GPIO INTERRUPT ISSUES

[NANDHU]

hlo sir , In my code there are 4 gpio interrupts,

if they comes at same time which will execute first.

There is any optional to assign priority to each gpio interrupts .

Hi.

Are you talking about the GPIOTE peripheral? Or are you talking about 4 different peripherals?

4 different peripherals:

The interrupt with the highest interrupt priority will execute first.

You can set the interrupt priority for your different peripherals in the sdk_config.h file

GPIOTE peripheral:

If they come in at the same time, it is not possible to know which interrupt will be executed, and only one interrupt will be executed most likely, the other 3 will be missed. You should add some sort of delay between the interrupts.

Best regards,

Andreas

Hi.

Sorry, I did not read your last reply as a question.

No, there is no option to do this, as I tried to explain in my previous reply.

Best regards,
