mfrc522-linux

Linux driver for the MFRC522 chip, written in C and Rust

Setup

There are two solutions to build this driver:

• Using a cross compilation toolchain
• Using a docker container

Build with a cross compilation toolchain

If you don't have a cross compilation toolchain, run activate.sh to download an arm toolchain. If you already have one, don't forget to set ARCH and CROSS_COMPILE environment variables.

Build and run the docker container

Build the docker image

docker build . --build-arg user_id=$(id -u $USER) --build-arg user_name=$USER -t linux-build-container # or any other tag you want

You only need to build the image once, as long as you don't change anything in the Dockerfile.

Start the container in interactive mode

docker run -it -v $PWD:/app linux-build-container # or the above tag

This will pop a shell and allow you to build linux from a Debian environment with the necessary packages.
