Setup

rustup toolchain install nightly-2021-01-07
rustup +nightly-2021-01-07 component add rust-src

If you get a permission denied error when accessing /dev/ttyACM0. You may need to add your user to a linux user group that has access to the serial interface. First, we find the group using:

ls -l /dev/ttyACM0

I get the following output on my machine:

crw-rw---- 1 root uucp 166, 0 Aug 19 03:29 /dev/ttyACM0

To add your username to uucp group, we run:

sudo usermod -a -G uucp $USER

Building

Build and run a standalone target

Use the following command to build and run the first executable target.

sudo -u $USER cargo run --bin 1-blink
