Hi,
I'm using the MFRC630 and I'l facing a strange behaviour. For information I used also the CLRC663 and I can see the same issue.
The byte where the collision has been detected by the reader is never present in the Fifo.
Here an example of my issue:
The third byte is having the collision at position 20, thus 3 bits are valids on the third byte. When I read the fifo length register, it returns a length of 2 and in the fifo the third byte is not present, even if I read more bytes. Consequently, I cannot continue the anticollision procedure.
I'm missing something?
I have read the demo kit code example and I cannot see any particular treatment to get the last byte.
I have the bit LoAlert set but when I uses only one card, this bit is also set and it seems not particularly anoying.
Any idea?
Thanks in advance
Hello,
Could you please provide more information about your project?
Are you taking as reference the NXP NFC Reader Library? If so, which example are you working with? Could you also confirm the Host MCU which controls the MFRC630?
Thank you.
Regards,
Ivan.
