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.

20:14daa48ffd4c 2015-03-23 Add ILI 9320/9325/9328 custom TFT932x class, parallel/spi 8/16bit, with orientation, scroll, pixelread, fastwindow.; Par8 and 16 tested, SPI not at all, needs checking if the CS toggle is necessary (see SPI8.cpp SPI16.cpp). File  Diff  Annotate
11:b842b8e332cb 2015-02-20 added auto_gram_read_format() to TFt inits. Even if write is set to 16bit RGB color, for some controllers the read cmd outputs 18bit BGR. Now that function will autodetect and set internal flags accordingly, so pixelread() is always correct. File  Diff  Annotate
