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

point in defining gdisp_lld_clear() unless the
