PN512 ReadRegister and WriteRegister commands

avgurt9 — Mon, 03 Feb 2025 09:45:12 GMT

Hello,

The PN532 microcontroller has the ReadRegister (D4 06 ADRh ADRl) and WriteRegister (D4 08 ADRh ADRl VAL) commands.

For smart card reader ACS ACR122U, they can be used, for example, as

FF 00 00 00 04 D4 06 63 05

and

FF 00 00 00 04 D4 08 63 05 04

Are there similar commands for the PN512 microcontroller (smart card reader ACS ACR1252U)?

Hello,

All the information available from commands to software examples can be found in the web page of the device PN512 | standard NFC frontend | NXP Semiconductors or the NFC Integrated Solution | NXP Semiconductors in case you are using this other one.

For the other reader set of commands, please reach out to the manufacturer.
