Fruit Jam OS is available in multiple languages: you download the zip file for the language of your choice. Each different language .zip contains a lvfontio compatible file that is capable of displaying the characters for that language. To install Fruit Jam OS, you need to first install CircuitPython on your Fruit Jam (described on the previous page). Once you have CircuitPython loaded on your Fruit Jam, the installation of Fruit Jam OS can begin.
Download
Click the button below to download the latest release of Fruit Jam OS for the US English language. For other languages go to the Fruit Jam OS release page and look for your desired language file under Assets.
Next unzip the downloaded file. Make a backup of your existing code.py under a different name on the CIRCUITPY drive (if you have an old program you want to keep). Then copy all of the follow files and folders from the unzipped file to the CIRCUITPY drive:
- apps/
- boot_animation/
- fonts/
- launcher_assets/
- lib/
- boot.py
- boot_animation.py
- code.py
- settings.toml
If you already have a settings.toml file with settings you want to keep, then merge the contents together using a text editor.
The copying process can take a few minutes, be patient.
Once it's complete, you're done! Make sure the Fruit Jam is plugged in to a compatible display.
You need to plug a USB keyboard and/or USB mouse into the Fruit Jam, before power up, to use the Fruit Jam OS user interface.
Press the reset button on the device. It will reboot, play the boot animation, and then go into the launcher.
