Library for oled-displays with SSD1306 or SH1106 display-controller connected with I2C at an AVR Atmel Atmega like Atmega328P.
|
|
|
|
This library allows you to display text or/and graphic at oled-display.
|
|
The library need less then 2000 bytes flash-memory in textmode and less then 3200 bytes in graphicmode so you can use oled-displays e.g with Atmega48PA.
|
|
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
|
|
|
|
exampel:
|
|
|
|
//****main.c****//
|
|
#include "lcd.h"
|
|
|
|
|
|
int main(void){
|
|
lcd_init(LCD_DISP_ON); // init lcd and turn on
|
|
|
|
lcd_puts("Hello World"); // put string from RAM to display (TEXTMODE) or buffer (GRAPHICMODE)
|
|
lcd_gotoxy(0,2); // set cursor to first column at line 3
|
|
lcd_puts_p(PSTR("String from flash")); // puts string form flash to display (TEXTMODE) or buffer (GRAPHICMODE)
|
|
#if defined GRAPHICMODE
|
|
lcd_drawCircle(64,32,7,WHITE); // draw circle to buffer
|
|
lcd_display(); // send buffer to display
|
|
#endif
|

//main loop
