Setting up PiJuice

The PiJuice provides a battery pack for a Raspberry Pi with 40 GPIO pins. PiJuice Documentation, PiJuice Software, and notes about the hardware.

Set up the PiJuice GUI

sudo apt-get install pijuice-gui

In the GUI make sure the battery is set up correctly, set the wakeup alarm for 08:59 every day, set the USER FUNC1 to /mnt/Trifle/rpi-offgrid/scripts/shutdown.py.

Due to hardware issues, the PiJuice's wakeup alarm gets disabled by the Pi on startup. So we update cron to make sure it gets re-enabled for next time. Edit crontab with crontab -e then add the following line:

@reboot /bin/sleep 30; /usr/bin/python3 /home/pi/PiJuice/Software/Test/wakeup_enable.py

Here we've added /bin/sleep 30; to make sure the RaspberryPi has set things up before enabling the wakeup.

Run the OSM Extract updater code:

0 9 * * * /bin/sleep 30; /mnt/Trifle/rpi-offgrid/scripts/osm-extract.sh
