Sleep mode / IDLE with PIC16F18345
Posted: Tue Jun 26, 2018 7:55 am
Hello everyone,
I want to implement the operation in low consumption with my PIC16F18345. l can operate in 3 mode:, IDLE, DOZE, SLEEP
-the mode type is set with the IDLEN bit of the CPUDOZE register
But here is my problem, is:
HOW TO ENTER IN LOW CONSUMPTION MODE ??
I would like :
1. Press the button, the led lights up and it returns to sleep mode.
2. 2nd press, we return to normal mode and the led flashes.
