This driver enables you to have two underlying drivers handling different hardware.
|
||
|
|
A choice is made at run-time of which driver to call based on which driver succeeds
|
||
|
|
to initialise first (init returns TRUE).
|
||
|
|
|
||
|
|
To use this driver:
|
||
|
|
|
||
|
|
1. Add in your halconf.h:
|
||
|
|
a) #define HAL_USE_GDISP TRUE
|
||
|
|
b) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD
|
||
|
|
c) Define these:
|
||
|
|
#define GDISP_VMT_NAME1(x) x##YourDriver1
|
||
|
|
#define GDISP_VMT_NAME2(x) x##YourDriver2
|
||
|
|
Note YourDriver1 & 2 are the basenames of the directories containing the driver.
|
||
|
|
Note that both drivers must be the same pixel format which is
|
||
|
|
GDISP_PIXELFORMAT_RGB565 by default. Alter gdispVMT/gdisp_lld_config.h if your
|
||
|
|
pixel format is different on both drivers.
|
||
|
|
d) Any driver specific defines. If both drivers use the same defines then they must
|
||
|
|
accept the same values for the define.
|
||
|
|
|
||
|
|
2. To your makefile add the following lines:
|
||
|
|
include $(CHIBIOS)/os/halext/halext.mk
|
||
|
|
include $(CHIBIOS)/os/halext/drivers/gdispVMT/gdisp_lld.mk
|
