Description:
Driver for OLED with 4-wire serial interface and I2C/SPI interface
Know restictions:
- Driver works only with SSD1306 hooked up over I2C or SPI (include corresponding header)
- Driver is written for 128x64 pixel displays (128x32 are only partly supported and need small further work)
- after using uGFX subsystem gdisp_lld_display() has to be called "by hand" to push framebuffer to display
To use this driver:
1. Add in your gfxconf.h:
a) #define GFX_USE_GDISP GFXON
b) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD
c) The following are optional - define them if you are not using the defaults below:
#define GDISP_SCREEN_WIDTH 128
#define GDISP_SCREEN_HEIGHT 64
2. If you are not using a known board then create a gdisp_lld_board.h file according to
given example files (or just stick with them) and ensure it is on your include path.
3. To your makefile add the following lines:
include $(GFXLIB)/drivers/gdisp/SSD1306/gdisp_lld.mk
4. Call gdisp_lld_display() every time you want to update display content
