<p><b>New page</b></p><div>Given that : <br />
<br />
- We use I2C to track the charging status and detect a power failure<br />
- We set the AUTO UPS switch to ON<br />
<br />
<br />
1 - We detect a power failure<br />
2 - Battery is now used and everything is alright<br />
3 - We decide to shut down the RPi<br />
4 - During the shutdown phasis, the power is back<br />
<br />
<br />
Q : What happens at 4? <br />
I think that actually, the RPi will just keep on shutting down normally but never powers ON again until a new power failure + power recovery cycle occurs. Which would be quite a problem and would defeat the purpose of this UPS device.<!-- migrated from Comments; original IP: 83.154.37.247 --></div>83.154.37.247
