Karl Zweimüller / UniGraphic

UniGraphic-Fork for ST7920-LCD-controller and SH1106. Tested with 128x64 LCD with SPI and 128x64-OLED with IIC

Dependents:   UniGraphic-St7920-Test AfficheurUTILECO

Fork of UniGraphic by GraphicsDisplay

Fork of the UniGraphic-Library for monochrome LCDs with ST7920 controller and 128x64-IIC-OLED-Display with SH1106-Controller

Had to adapt LCD for following reasons:

  • Give access to screenbuffer buffer[] to parent class
  • pixel() and pixel_read() as they are hardware-dependent
  • added reset-pin to IIC-Interface

GraphicDisplay:: sends buffer to LCD when auto_update is set to true.

Testprogram for ST7920 can be found here:
