TI-H: magnetic reader
Magnetics readers has two signals (three).
1. Card present
2 Clock
3 Data.
The clock rate depends on the speed you pass the card and the data
density, if you have a 75bpi card and you pass it at 1"/s the you have
75hz .
i think you'll need a interrupt based system, or with poll :
look at card presset
card pressent asserted:
poll clock, in the falling edge sample data.
that's all.
if you need further explanations let me know.
