Example Description
|
|
|
|
This example describes how to use deep sleep api.
|
|
|
|
Requirement Components:
|
|
a LED
|
|
a push button
|
|
|
|
Pin name PC_4 and PC_5 map to GPIOC_4 and GPIOC_5:
|
|
- PC_4 as input with internal pull-high, connect a push button to this pin and ground.
|
|
- PC_5 as output, connect a LED to this pin and ground.
|
|
|
|
In this example, LED is turned on after device initialize.
|
|
User push the button to turn off LED and trigger device enter deep sleep mode for 10s.
|
|
If user press any key before sleep timeout, the system will resume.
|
|
LED is turned on again after device initialize.
|
|
|
|
It can be easily measure power consumption in normal mode and deep sleep mode before/after push the putton.
|
|
|
|
NOTE: You will see device resume immediately at first time.
|
|
It's because the log uart is a wakeup source and it buffered a wakeup event when DAP is used.
|
|
The symptom won't appear if you use power source on R43 and only power on module. |
