proxmark3/armsrc/LCD.c
edouard@lafargue.name 6658905f18 Initial commit for the firmware. Used the 20090306_ela version as baseline.
It is identical to the popular 20081211, with the doob addition (20090301), a
linux client, and two additional commands for LF analysis. Let me know if
you find issues here!
