[FR] Add support for PN5180 - RFID

[iz8mbw]

Hi!
Is it possible to add NXP Semiconductors PN5180 RFID?

Docs Libraries:

https://github.com/ATrappmann/PN5180-Library
https://github.com/taymuur/ESP32-PN5180-PN532
https://github.com/playfultechnology/arduino-rfid-PN5180
https://github.com/dotnet/iot/tree/main/src/devices/Pn5180
https://docs.nanoframework.net/devicesdetails/Pn5180/README.html

Many thanks!

What's the USP (Unique selling point) for adding support for this board? We already have support for several, differently interfaced, RFID boards...

[iz8mbw]

The PN5180 can read the card/tag up to 15 cm.
RC522 and PN532 can reach some cm only.

The second library you linked is apparently also supporting the PN532, which we do support.
So maybe it is just a matter of adding the right I2C addresses to the selection?

[iz8mbw]

PN5180 uses different library than PN532.

[tonhuisman]

PN532 does support SPI, I2C and serial (AFAIR), but we support it in I2C mode only. PN5180 only has support for SPI interface.

[TD-er]

As far as I can remember is SPI support for the PN532 far from stable.
Thus when this PN5180 will be added, it must then be a new plugin as it can't use the same bus as the PN532.

Have to see if it is already available for a reasonable price at the usual channels.

It looks like the PN5180 is an NFC reader, not a RF-id.

Have to see if it is already available for a reasonable price at the usual channels.

It costs about 5 Euro on AliExpress.
