CRC error #12

Open e4awais opened 9 years ago

e4awais commented 9 years ago

how to clear a crc error when it happens ?

a soft/hard reset does not solve the problem.

need to clear the crc error without powering up the circuit again.

appreciate all the help.

thanks

Tough question. It never happened to me. Here on page 29 is a section on the CRC processor http://www.nxp.com/documents/data_sheet/MFRC522.pdf

thanks,

but when i flush the fifo buffer, even if i re-initialize, the chip simply does not respond.

any ideas ?

thanks

Does it solely happen when you use this library? Maybe you could try using an Arduino or any other platform to test the functionality of the reader.

i m using another library posted on github, i posted my question there as well.

my controller is a 32 but arm.

the code works fine except the crc error.
