Hi,
I asked previously about power efficiency for the NRF52840 SDK version V15 (https://devzone.nordicsemi.com/f/nordic-q-a/36083/maximal-power-efficiency-in-main-loop).
At that time I used the timer to poll the SPI using SPIM and timer event callbacks. I got the info that all I need is the main loop:
for (;;) sd_app_evt_wait();
I would like to add incoming interrupt callbacks (using GPIOs) while keeping power management efficient.
Do I need to change my main loop?
Thanks,
Daniel
