JTAG is both an executable binary that can be run, and a library that can be used in Rust programs.
Installing cuterunner-test zoidberg-coolrunner-test executables
Assuming you have Rust/Cargo installed, run this command in a terminal:
cargo install jtag
It will make cuterunner-test zoidberg-coolrunner-test commands available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall jtag uninstalls.
Adding jtag library as a dependency
Run this command in a terminal, in your project's directory:
cargo add jtag
To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:
jtag = "0.0.3"
The jtag library will be automatically available globally.
Read the jtag library documentation.
