+
+Driver for LCD with 4-wire serial interface (65k colors).
+
+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: GDISP_NEED_MULTITHREAD
+
+ c) If you are not using a known board then create a gdisp_lld_board.h file
+ and ensure it is on your include path.
+ Use the gdisp_lld_board_st_stm32f4_discovery.h file as a basis.
+ Currently known boards are:
+ BOARD_ST_STM32F4_DISCOVERY
+ Board configuration assume that you have STM32_PWM_USE_TIM4 set to TRUE in your mcuconf.h.
+
+ d) The following are optional - define them if you are not using the defaults below:
+ #define GDISP_SCREEN_WIDTH 240
+ #define GDISP_SCREEN_HEIGHT 320
+
+2. To your makefile add the following lines:
+ include $(GFXLIB)/drivers/gdisp/HX8347D/gdisp_lld.mk
