I've made some test with a proximity card:
1) I've read with a usb Rfid reader, so i have this "0004959302"
2) I've read with the Rfid (EM4100) reader plugged in Rsr232 of my pc, and i obtain "2F004BAC46"
3) I've read with the Rfid (EM4100) reader and netduino and i have this array of byte
63, 51, 46, 198, 198, 25, 47, 95, 94, 25, 50, 121, 61, 126
The data structure should be this:
STX (02 HEX)
DATA (10 HEX)
ETX (03 HEX)
But I don't understand how can read card number (0004959302) from this byte array.
anyone has experienced with the wiegand protocol?
I have to interface Netduino with an RFID reader (EM4100) and use the Wiegand protocol for serial communication.
I do not know where to start.
