Monitor PIN change

[Amit]

I am new to NRF52832. I want to monitor continuously PIN 3 where I have connected USB to check whether my USB is connected or not. How can I do that. Please reply ASAP.

Hi..Amit

first define PIN 3 and After that ,create timer instance for repeated mode and start it.

then initalize , configure nrf_drv_gpiote_init driver based on ur configuration and enable input event on it.

for more information u can look at example pin_change_int in SDK example folder.

Regards.

it is very simple. just configure "sense" in nrf_drv_gpiote_in_config_t struct. then it will generate event when change.
