SSD2119: backlight control
- Backlight uses PWM on TIM4 CH2. - Updated readme. - Updated gdisp_lld.c: moved from lld_gdisp_* to gdisp_lld_* functions names format. - One forgotten GDISP_LLD() macro removal. - General code cleanup (make diff with -w parameter ;))ugfx_release_2.6

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_embest_dmstf4bb_fsmc.h or gdisp_lld_board_embest_dmstf4bb_fsmc.h file as a basis.
|
||||
Currently known boards are:
|
||||
BOARD_EMBEST_DMSTF4BB - GPIO interface
|
||||
BOARD_EMBEST_DMSTF4BB_FSMC - FSMC interface
|
||||
|
||||
d) The following are optional - define them if you are not using the defaults below:
|
||||
#define GDISP_SCREEN_WIDTH 320
|
||||
#define GDISP_SCREEN_HEIGHT 240
|
||||
|
||||
2. To your makefile add the following lines:
|
||||
include $(GFXLIB)/drivers/gdisp/SSD2119/gdisp_lld.mk

Description:
|
||||
|
||||
Driver for LCD with 16-bit interface in 8080 mode (65k colors).
|
||||
|
||||
To use this driver:
|
||||
|
||||
1. Add in your halconf.h:

Currently known boards are:
|
||||
BOARD_EMBEST_DMSTF4BB - GPIO interface
|
||||
BOARD_EMBEST_DMSTF4BB_FSMC - FSMC interface
|
||||
Both board configurations assume you have STM32_PWM_USE_TIM4 set to TRUE in your mcuconf.h.
