All pins specified above must be on the same port. -*/ - -/** \file - * - * Driver header for a TTL Magnetic Card reader device (such as the Omron V3B-4K). - */ - -#ifndef _MAGSTRIPEHW_H_ -#define _MAGSTRIPEHW_H_ - - /* Includes: */ - #include <avr/io.h> - - #include <LUFA/Common/Common.h> - #include "Config/AppConfig.h" - - /* Private Interface - For use in library only: */ - /* Macros: */ - /** Mask of the track data, clock and card detection pins. */ - #define MAG_MASK (MAG_T1_DATA | MAG_T1_CLOCK | \ - MAG_T2_DATA | MAG_T2_CLOCK | \ - MAG_T3_DATA | MAG_T3_CLOCK | \ - MAG_CARDPRESENT) - - /* Public Interface - May be used in end-application: */ - /* Inline Functions: */ - /** Initializes the magnetic stripe card reader ports and pins so that the card reader - * device can be controlled and read by the card reader driver.
