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)
|
||||
- Flushing is required for this driver
|
||||
|
||||
To use this driver:
|
||||
|
||||
1. Add in your gfxconf.h:
|
||||
a) #define GFX_USE_GDISP TRUE
|
||||
|
||||
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/SSD1322/gdisp_lld.mk
