+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
+
+ #define GDISP_CS 0
+ #define GDISP_RS 1
+ #define GDISP_WR 2
+ #define GDISP_RD 3
+#endif
