# Example: deep sleep
|
||
|
|
|
||
|
|
This example illustrates usage of deep sleep mode and various wakeup sources.
|
||
|
|
|
||
|
|
The following wake up sources are configured:
|
||
|
|
|
||
|
|
- Timer: wake up the chip in 20 seconds
|
||
|
|
- EXT1: wake up the chip if any of the two buttons are pressed (GPIO25, GPIO26)
|
||
|
|
- Touch: wake up the chip if any of the touch pads are pressed (GPIO32, GPIO33)
|
||
|
|
- ULP: wake up when the chip temperature changes by more than ~5 degrees Celsius (this value hasn't been characterized exactly yet).
