I am trying to get the lowest power possible on NRF52 ItsyBitsy, and I saw the discussion regarding the hardware side(LED, LDO, etc..)
My question is that I put the system to system off power state.
Code: Select all
void loop() {
NRF_POWER->SYSTEMOFF = 1;
}
Code: Select all
#define BUTTON 29
nrf_gpio_cfg_sense_input(BUTTON, NRF_GPIO_PIN_PULLUP, NRF_GPIO_PIN_SENSE_LOW);
Is this expected behavior? Can I do something to make it go back to the app(I know it won't go back to where it enters power down, because the RAM will be lost)?
