# OLED for AVR mikrocontrollers
|
||||||
|
Library for oled-displays with SSD1306, SSD1309 or SH1106 display-controller connected with I2C or SPI at an AVR Atmel Atmega like Atmega328P.
|
||||||
|
|
||||||
|
Upstream: [https://github.com/Sylaina/oled-display/](https://github.com/Sylaina/oled-display/)
|
||||||
|
|
||||||
|
<img src="https://github.com/Sylaina/oled-display/blob/master/oled.jpg?raw=true" width="500">
|
||||||
|
|
||||||
|
This library allows you to display text or/and graphic at oled-display.
|
||||||
|
The library need less than 2 kilobytes flash-memory and 3 bytes sram in textmode, in graphicmode library need less than 3 kilobytes flash-memory and 1027 bytes static sram so you can use oled-displays e.g with Atmega48PA (only with textmode).
|
||||||
|
Library is only tested with 128x64 Pixel display, lower resolution not tested but should work too.
|
||||||
|
|
||||||
|
If you want to use your own I2C library you have to fit i2c-function at lcd-library.
|
||||||
|
Settings for I2C-bus have to set at i2c.h
|
||||||
|
Settings for display have to set at lcd.h
|
||||||
|
|
||||||
|
If you want to use characters like e.g. ä set your compiler input-charset to utf-8 and your compiler exec-charset to iso-8859-15 (look at makefile line 115).
|
||||||
|
|
||||||
|
Testcondition: Display: SSD1306 OLED, Compiler Optimizelevel: -Os, µC: Atmega328p @ 8 MHz internal RC
