PN7362 communication from ESP32-WROOM-32

[lv]

Hi, we are working on a contactless application project, we use the ESP32-WROOM-32 for BLE and WiFi functionality, on the PCB we connected the ESP32 using I2C to PN7362, we couldn't find any specific documentation for this type of situation.

Where can I find some documentation?

Thanks in advance

Hello @lv .

About PN7362  I2C information please kindly refer to the datasheet as the link.

URL:https://www.nxp.com/docs/en/data-sheet/PN7462.pdf.

And how to use it please refer to the PN7462 family HW user manual as the link.

URL:https://www.nxp.com/docs/en/user-guide/UM10858.pdf.

So communication to ESP32-WROOM-32, the customer can design depending on the upper documents.

Have a nice day.

Hi @fangfang,

Thank you for the fast response.

I didn't describe the problem correctly, I am sorry, we already managed to connect ESP32 chip to PN7362 on the PCB following the HW documentation.

The problem is that we didn't find documentation about the firmware installed on PN7362 and how to instruct the PN7362 using ESP32 MCU connected with I2C to do operations like read/write NFC tag or emulating an NFC TAG.

Thanks in advance

Hello @lv,

For ESP32-WROOM-32 we have not the example code for it.

But we have the library for the PN6362  as the link.

URL:https://www.nxp.com/design/designs/nfc-reader-library-software-support-for-nfc-frontend-solutions:NF....

The library provides the example of  read/write NFC tag or emulating an NFC TAG.

Hope it help you.
