+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
