---

simple avr program exposing some oled library functions over a serial connection, uses a patched version of [oled-display:fa446f6](https://github.com/Sylaina/oled-display/tree/fa446f61112e36c5753a6f81c5caf5b819155650) for controlling the display. currently only tested on an ssd1306 (128x32 and 128x64) display with arduino uno, but it should be straight forward to make it work on other devices.

## usage

open a serial connection baudrate `115200`,\

use the commandset:

cmd      | action

---      | ---

Wn str   | write *str* to row *n*

Px,y str | write *str* to position *x*,*y*

I        | invert screen

C        | clear screen

R        | reset device (experimental, only for uno, requires pin connected to reset)

## todo

- add more commands

- strip down/extend oled library more
