Hello,
I am working on nRF51822, SDK12.3.0 in IAR workbench.
I am use init pin 2 as an interrupt.
Device will advertise for 20 minute after 20 minute device go to sleep.I want to wake up the chip only when pin 2 detect falling edge. I have used following lines to configure the input pin before device going to sleep.
nrf_gpio_cfg_sense_set(2, NRF_GPIO_PIN_SENSE_LOW); err_code = sd_power_system_off(); APP_ERROR_CHECK(err_code);
Since I can either put sense to high or low. For e.g. if I Use "GPIO_PIN_CNF_SENSE_Low" and if pin 2 input is low, the nRF wakes up as soon as i put it in system off mode.
Is there any way to make sense functionality into sensing the edge rather than level ?
Thanks & Regards,
