- NOTE: The user of this include file MUST define the following macros
- prior to including the file:
-
- MAG_T1_CLOCK_PIN Pin connected to Track 1 clock wire (ie. PORTC1)
- MAG_T1_DATA_PIN Pin connected to Track 1 data wire (ie. PORTC2)
- MAG_T2_CLOCK_PIN Pin connected to Track 2 clock wire (ie. PORTC3)
- MAG_T2_DATA_PIN Pin connected to Track 2 data wire (ie. PORTC0)
- MAG_T3_CLOCK_PIN Pin connected to Track 3 clock wire (ie. PORTC5)
- MAG_T3_DATA_PIN Pin connected to Track 3 data wire (ie. PORTC6)
- MAG_CLS_PIN Pin connected to card loaded wire (ie. PORTC4)
- MAG_PIN PIN macro for the reader's port (ie. PINC)
- MAG_DDR DDR macro for the reader's port (ie. DDRC)
- MAG_PORT PORT macro for the reader's port (ie. PORTC)
-
- The example macros listed above assume that the Track 2 data wire is
- connected to pin 0 on port C, the Track 2 clock wire is connected to
- pin 3 on port C (similarly for Tracks 1 and 3), and the card loaded
- wire is connected to pin 4 on port C.
-
- If the magstripe reader you are using only reads one or two tracks,
- then set the clock and data pins for the tracks it doesn't read to a
- pin that is unused. For example, on the AT90USBKey, any of the pins on
- port C that do not have wires attached will be unused since they are
- not connected to any onboard devices (such as the joystick or
- temperature sensor).
-
- Connecting wires to pins on different ports (ie. a data wire to pin 0
- on port C and a clock wire to pin 0 on port D) is currently
- unsupported. All pins specified above must be on the same port.
