MFRC630 Authentication Mifare classic 1k

[ihsan]

I use MFRC630 chip with Mifare Classic 1k. 

I use UART interface between mcu and mfrc630. And i read card uid. but when i try to write and read a block, i could not read and write.

I set the Transmit CRC and receiver CRC. But when i read the interrupt register 1, the chip send 0x47. we get error register and status register equals zero. 

Here is the pseudo code of authentication:

-Load Key

-IRQ0EN

-IRQ1EN

 -Timer0config

-IRQ0Clear

-IRQ1Clear

-MFAuthent(MFAuthent Command is consisted of 60h or 61h, (block address), (card serial number byte0),(card serial number byte1), (card serial number byte2),(card serial number byte3))

-Set Rx and Tx CRC(CRC16)

-IRQ0EN

-IRQ1EN

-Timer0config

-IRQ0Clear

-IRQ1Clear

-Mifare Read Block.

Hello ihsan,

My apologies for the delay in answering back, thank you for using our products.

Please check our documentation for using MFRC630 without the library:

Or if you prefer, migrate the library for the MCU you are using:
