Good morning,
I am studying to try understand better how to control operations mode: sleep, deep sleep and wake-up.
Take a look in the comparinson between microcontrollers modes: Compare IP
We can see that Cortex-M4 (RAK4631) is a good option about power management. Reading in the Cortex-M4 Devices - Generic User Guide in topic “4.3.6 System Control Register”, I found where to control the modes:
-
SLEEPDEEP: 0 = sleep and 1 = deep sleep
-
SLEEPONEXIT Indicates sleep-on-exit when returning from Handler mode to Thread mode:
0 = do not sleep when returning to Thread mode.
1 = enter sleep, or deep sleep, on return from an ISR.
Setting this bit to 1 enables an interrupt driven application to avoid returning to an empty
main application.
@beegee , in your bootloader development for WisCore_RAK4631_Bootloader , I found the sleep control in the file nrf_power.h.
I would like to know how to control the sleep/wake modes from my codes for RAK4631.
Regards,
Claudio
