PiSugarSButtonActive.sh and safe shutdown on S plus?
having trouble figuring out what i need to download for my S plus to shutdown the pi when the power is low or when I pres the button. I saw the PiSugarSButtonActive.sh but i'm unsure what it does and how to use it properly.
For the "button shutdown" on my PiSugar S (without the plus) my approach was this:
- get said script and edit line 37 and/or 39 to read "sudo shutdown -h now".
- edit your crontab to start the script at boot
- push the button: magic :-)
As for the automatic shutdown on low battery: isn't that a feature anyway? In the wiki it says: "When the battery voltage is lower than 3V, PiSugar S will shut down immediately". Mine never ran empty, but I would read "shut down" as a regular shutdown like you could do with "shutdown -h now". Otherwise you would need to read the battery level and react to that. I can think of some external circuit reading the voltage but it seems PiSugar power manager might be able to accomplish that via I2C [ adress 0x75(BAT)].
I know very little about linux so how do I get the script, how do I edit the script, how do I edit the crontab ?
