Hello,
MSP430FR6877 is connected to MFRC522 through SPI, the SPI communication is fine, writing to/reading from registers is fine.
However when it comes to reading from cards, the data count in the FIFO is always 0.
I tried the digital self test, it returns version 1 (0x91) in the version register, but also the FIFO doesn't have data and so the test fails.
So does this have anything to do with MSP430FR6877? Does that mean that the RFID chip itself is working fine and the problem is in the antenna?
