RFID Reader

Latest source code is available at

Hex file is available only for ATmega8 at 16MHz. Host executable is available only for Intel Macs with latest software update.

Currently you need to request ID from a device.
Example: ./set-led status

Receiving ID when tag is scanned is still in progress. (I have some problems with USB interrupt-in)

Components for USB are connected as usual. (D+ on PB2, D- on PB4). Green LED is connected to PC5 (28), yellow LED to PC3 (26). TX from RFID module is connected to RX on AVR (PB0 on ATMega8/168).
