Having problems running Sudo Python read.py #19

Open Grahamrich1 opened 7 years ago

Grahamrich1 commented 7 years ago

I have been getting an error "can't open device: No such file or directory" which I have nailed down to the line

pi@raspberrypi:~/gr_programs/RFID/SPI-Py/MFRC522-python $ sudo python read.py Opening file. importing MFRC533. Opening signal Signal open MIFAREREADER = can't open device: No such file or directory

This is my modified .py

print "Opening file." print "importing MFRC533." import MFRC522 print "Opening signal" import signal print "Signal open" continue_reading = True print "MIFAREREADER =" MIFAREReader = MFRC522.MFRC522()

print "Def card AtoC =" cardA = [5,74,28,185,234] cardB = [83,164,247,164,164] cardC = [20,38,121,207,132]

print "Def end read =" def end_read(signal, frame): global continue_reading continue_reading = False print "Ctrl+C captured, ending read." MIFAREReader.GPIO_CLEEN()

signal.signal(signal.SIGINT, end_read)

Any idea on what I doing wrong?
