Ich bin ein absoluter Neuling und versuche gerade zunächst einmal ein gerät zu bauen, welche Legic-RFID-Karten ausliest. Hierzu habe ich einen Kartenleser an meinen Raspberry Pi angeschlossen (/etc/usb/hiddev0). Dann habe ich folgendes Python-Script zusammen kopiert/geschrieben.
Code
import sys
fp = open('/dev/usb/hiddev0', 'rb')
while True:
buffer = fp.read(8)
list_ascii=[ord(c) for c in buffer]
for c in buffer:
if ord(c) > 0:
print list_ascii
print "\n"
Alles anzeigen
Das funktioniert auch soweit, nur das der Reader beim auflegen einer RFID-Karte dann folgendes ausspuckt:
