To use this driver:
1. Add in your halconf.h:
a) #define GFX_USE_GDISP TRUE
b) Any optional high level driver defines (see gdisp.h) eg: #define GDISP_NEED_MULTITHREAD TRUE
c) One (only) of:
#define GDISP_USE_GPIO
#define GDISP_USE_FSMC
d) If you want to use DMA (only works with FSMC):
#define GDISP_USE_DMA
#define GDISP_DMA_STREAM STM32_DMA2_STREAM6 //You can change the DMA channel according to your needs
2. Edit gdisp_lld_panel.h with your panel properties
3. To your makefile add the following lines:
include $(GFXLIB)/drivers/gdisp/RA8875/gdisp_lld.mk
Example FSMC config with DMA:
#define GDISP_SCREEN_WIDTH 480
#define GDISP_SCREEN_HEIGHT 272
#define GDISP_USE_FSMC
#define GDISP_USE_DMA
#define GDISP_DMA_STREAM STM32_DMA2_STREAM6
#if defined(GDISP_USE_GPIO)
#define GDISP_CMD_PORT GPIOC
#define GDISP_DATA_PORT GPIOD
