Print USB serial data to an OLED display using Rust and AVR-C

UDOO Display

Using the embedded atmega32u4 in an UDOO Bolt Gear, display text received over a USB serial interface on an SSD1306 OLED screen.

Main application logic and display driver is written in Rust. USB serial implementation uses the atmega32u4-usb-serial crate.

Run cargo make build to compile and cargo make flash to upload.

Write data to serial port to display on the screen. For example: ip addr | grep -Po '(?<=inet)\s(?!127)[^/]+' > /dev/ttyACM0, to show the current IP address. Write a null character to clear screen: echo -ne '\0' > /dev/ttyACM0.

Consider making a library from this

Hey!

I got curious and found this project after your comment in the avr-hal issue. This looks really cool!

As you know, the HAL currently does not have any USB support. So I've got to ask: Would you be interested in making a library from this codebase you have here? An atmega32u4-usb crate, using the existing C libraries via FFI, would be quite useful to substitute the missing HAL support for the time being ...
