RDM6300 addtional output formats, XOR Checksum

[arne123]

I had recently some issue with the RDM6300 reader, during debugging I found I would be very nice to have matching Numbers between the entries in the Database and the ones printed on the ID-Cards itself.

On the ID-Cards I am having are two Numbers, one 10 Digit Number with leading zeros and a fractional number.
Both are based on the same card number, just with a different representation. The Format is called Wiegand26.

Also I added a XOR checksum check as it is described in the RDM6300 Manual.

Additionally I tried to Address the dependency Topic of #1105, but this is mostly untested, since I don't have this modules available. It would be very nice if someone could support here.

Does Anyone know, what was the Intention here,
I am not sure if this still works as it was originally intended or even was functional before.
(what can threw or could throw a ValueError?)

[arne123]

Does this still makes sense here?
Means 2nd swipe will not be possible with RDM6300
Is this intentionally? Was there maybe a Good reason for this?

Hey @arne123,
the CI currently fails (e.g. https://github.com/MiczFlor/RPi-Jukebox-RFID/actions/runs/597448418).

./scripts/Reader.py.experimental:170:37: F821 undefined name 'MIFARE_WAIT_FOR_ENTRY'
        self.device.set_max_retries(MIFARE_WAIT_FOR_ENTRY)
                                    ^
1     F821 undefined name 'MIFARE_WAIT_FOR_ENTRY'
1
Error: Process completed with exit code 1.

I think the import doesn't work right. Could you have a look?
Thanks

I think I got it working with adding
from py532lib.mifare import MIFARE_WAIT_FOR_ENTRY

I can not test the Module without active i2c, I just checked for the availability of MIFARE_WAIT_FOR_ENTRY
which seems to have the right value (255/0xFF).

Can you do me a favor and test, if this will work in your environment?
Or should I just update the PR?

class Pn532Reader:

    def __init__(self):
        from py532lib.i2c import Pn532_i2c
        from py532lib.mifare import Mifare
        from py532lib.mifare import MIFARE_WAIT_FOR_ENTRY
        print(MIFARE_WAIT_FOR_ENTRY)  # just for test
        pn532 = Pn532_i2c()
        self.device = Mifare()
        self.device.SAMconfigure()
        self.device.set_max_retries(MIFARE_WAIT_FOR_ENTRY)


    def readCard(self):
        return str(+int('0x' + self.device.scan_field().hex(), 0))

    def cleanup(self):
        # Not sure if something needs to be done here.
        logger.debug("PN532Reader clean up.")`

Unfortunately I don’t have that reader to test it

Fixed the import in #1312
