This low level driver is a test stub that doesn't talk to any
real hardware. It is included to allow testing of the compilation
process.
Do not use this driver as a template for new drivers. Use the
templates/gdispXXXXX directory for that.
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)
you want to compile test eg: GDISP_NEED_MULTITHREAD
2. To your makefile add the following lines:
include $(CHIBIOS)/os/halext/halext.mk
include $(CHIBIOS)/os/halext/drivers/gdispTestStub/gdisp_lld.mk
