A simple OneDrive Slideshow designed to be run on a Raspberry Pi (running Linux), or any Windows or Linux desktop OS.

For pre-built binaries, look at the Artifacts attached to any successful build of main.

The app will authenticate to OneDrive via the "Device Flow": it will provide a URL (that you will need to open on another device where you can log in to OneDrive) and a code to enter.

You will need to create a file called slideshow.txt in the root of your OneDrive that configures the slideshow. This is a JSON file with the basic format of:

{
    "directories":
    [
        "Pictures"
    ],
    "interval": 5
}

• directories is the list of directories to search recursively for images.
• interval is the approximate number of seconds between each image.

OneDrive Slideshow is built in Rust, so building it requires the Rust toolchain and then running:

cargo build --release

To build for the Raspberry Pi, you can either do it on-device or via cross:

cargo install cross
cross build --release --target armv7-unknown-linux-musleabihf

The most reliable way I've found to automatically start this on Raspberry Pi OS is to add an entry to ~/.config/lxsession/LXDE-pi/autostart: https://www.raspberrypi-spy.co.uk/2014/05/how-to-autostart-apps-in-rasbian-lxde-desktop/ (Note that the body of the article uses the older ~/.config/lxsession/LXDE/autostart path, but one of the comments has the updated LXDE-pi path).
