kobo-rs is a minimal Rust library for interacting with modified Kobo e-readers. This is designed for use in applications running on the Kobo, not over the network.

Since we are cross-compiling (please don't try compiling software on a Kobo), we need a few tools.

docker pull ewpratten/kobo-cross-armhf:latest
cargo install cross

With that out of the way, the library can be built with:

cross build --target arm-unknown-linux-musleabihf

You'll need to do these same steps with your own applications.

To build and run the display example, you'll need to do the following:

cross build --target arm-unknown-linux-musleabihf --release --example display

Then, copy the binary to the Kobo's internal storage and execute the following command on the device:

/mnt/onboard/display
