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.
