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

The new GDISP driver is an architecture independent rewrite of the GLCD interface.
This new architecture independence should allow many new low level drivers to be easily added.
The new GDISP driver is an architecture independant rewrite of the GLCD interface.
This new architecture independance should allow many new low level drivers to be easily added.
GDISP allows low-level driver hardware accelerated drawing routines while providing a software emulation
if the low level driver can not provide it. A basic low level driver now only requires 2 routines to be written.
A glcd.h compatibility file has been included that allow applications written to use the existing GLCD driver to
A glcd.h compatability file has been included that allow applications written to use the existing GLCD driver to
use the GDISP driver with little or no change.
It is written in the ChibiOS style with ChibiOS style includes and documentation.

Don't bother coding for obvious similar routines if
there is no performance penalty as the emulation software
makes a good job of using similar routines.
