+To use this driver:
+
+1. Add in your halconf.h:
+ a) #define GFX_USE_GINPUT TRUE
+ #define GINPUT_NEED_DIAL TRUE
+ #define GINPUT_NEED_GADC TRUE
+ d) If you are not using a known board then create a ginput_lld_toggle_board.h file
+ and ensure it is on your include path.
+ Use the ginput_lld_dial_board_example.h file as a basis.
+ Currently known boards are:
+ Olimex SAM7-EX256
+
+2. To your makefile add the following lines:
