The PN532 command PN532 command (S50)

Note: 1, this article only for pn532 and S50 communication card.2, Pn532 and PC for the serial communication, baud rate 115200,8 data bits, 1 stop bit and parity none

3, unless otherwise stated, all sent to receive information andfollow the general frame format

4, all the operation of the EEPROM must be authenticatedGeneral frame format: (normal send and receive commands anddata to follow this format)

ACK frame format:

NACK frame format:

Extended frame format:

Error: frame format (prompt application layer error,unrecognized command or parameter error)

Command set:

Wake up: 5555000000000000 FF 03 FD 0000000000000000D4 14011700

Explanation: 1, 5555000000000000 and 000000000000 wake-upcommand is special, only this part of the order, on behalf ofwaiting

2, the SAMConfiguration command, where 01 represents aconfiguration for the normal mode

Example: 0000 FF 00 FF 000000 return information FF 02 FE D5

151600

Explain:

1, ACK

2, D5 15 performed correctly and completed

Get UID:00 FF 04 FC 4A 0100 D4 00 E1 00

2, the baud rate value

Example: return data: 0000 FF 00 FF 000000 FF 0C F4 D5 4B010100040804 FB 0E E2 0B D8 00

Identity verification: 0000 FF LEN LCS D4 Addr FF FF FF FF FF400160 FF UID DCS 00

Example: enter the command: 0000 FF 0F F1 D4 FF FF FF FF 40016007FF FF FB 0E E2 0B 9400

Read: 0000 FF 05 FB D4 400130 Addr DCS 00

Explain:

The InDataExchange command, said the 01 target card number 30that read operations, Addr is to read the block addressExample: enter the command: FF 05 FB 0000 D4 40013004 B7 00Interpretation: 04 to read the block address

Return information: 0000 FF 00 FF 000000 FF 13 ED D5 4100 FFFF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FA 00

Explanation: 00 read success behind the data read dataWrite operation: 0000 FF 15 EB D44001 A0 Addr BlockData 4F 00Explain:

Addr to write the address of BlockData to write data.Example: enter the command: FF 15 EB 0000 D4 4001 A0

0401010101010101 0101010101010101 013700

Interpretation: in sector2 block1 write 01

Output: 0000 FF 00 FF 000000 FF 03 FD D5 4100 EA 00

Explanation: 00 successful writing

Enter the command: FF 05 FB 0000 D4 40013004 B7 00

Explanation: read the block data

Output: 0000 FF 00 FF 000000 FF 13 ED 4100010101010101 D50101010101010101 0101 DA 00

Explanation: obviously, the data read write data

Increase of operation: 0000 FF 09 F7 D4 4001 C1 Addr 01000000DCS 00

Reduction operation: 0000 FF 09 F7 D44001 C0 Addr 01000000 DCS

Transfer operation: 0000 FF 05 FB D4 4001 B0 Addr DCS 00Store operation: 0000 FF 05 FB D4 4001 C2 Addr DCS 00Turn off the radio frequency: 0000 FF 04 FC D4 320100 F9 00Explanation: the command for RFConfiguration 01, RF field said,the 00 turn off radio frequency

Example: enter the command: FF 04 FC 0000 D4 320100 F9 00Output: 0000 FF 00 FF 000000 FF 02 FE D5 33 F8 00

Explanation: D5 33 is finished, RF Field off

A M1 card, command analysis (No. 1 M1 card)

Key verification: according to the block number to verify the

same sector as long as verification of one piece, can operatewith a sector in the 4 block.

The operation of another sector, but also re verification.1, initialize the PN532 to the normal state
