Wake up from deep sleep using LPCOMP

[Judge]

Hi everyone, I have the following problem: I want to use LPCOMP to wake the nrf52840 from a deep sleep so how should I use it?

Hi,

You can look at lpcomp example in SDK. CPU will wake up on configured event (see NRFX_LPCOMP_CONFIG_DETECTION in sdk_config.h) Though this example doesn't put CPU in sleep, you can replace main loop code with __WFE() instruction to fix this:

    while (1)
    {
        __WFE();
    }
