Fork of DMSupport by Embedded Artists

DMBoard.cpp@36:92193dc72995, 2015-03-20 (annotated)

Committer:

Date:
Fri Mar 20 14:44:06 2015 +0000
Revision:
36:92193dc72995
Parent:
34:fc366bab393f 
Modified DMBoard interface to always have the touchPanel() and display() functions even if the touch/display has been disabled in dm_board_config.h to allow e.g. AppTouchCalibration to compile (even if it will never be used it must still compile)
