GPIOTE library in SDK7.2 with nRF51422

[Yoshiyuki Kasai]

I'm using GPIOTE library to check the change of two switch inputs. Normally it works well, but rarely GPIOTE_IRQHandler become never happen even if the pin level changes. I think the reason is bounds like noise. For example, the pin changes many times while serving this interrupt.

Could you please tell me the solution?

If the pin changes so fast that the interrupt could not finish then it is very normal that you are missing few events. What is the source of that noise on your pin?

GPIOTE_IRQHandler become hung-up <--- What do you mean by this.
