5.10 RFID not working with new LCD wifi controller #807

Closed rbray89 closed 3 months ago

I've been attempting to get RFID working on the new LCD wifi unit.

I've connected a PN532 board via the SDA/SCL I2C header on the board, but can't get scans to show up. The PN532 powers up fine.

It seems the RFID config also is always available, even if no hardware is attached.

Created https://github.com/OpenEVSE/openevse_esp32_firmware/pull/819 to address this issue.

Looks like SDA and SCL might be swapped in the pinout.
