NFC Reader library - multiple RC663 on one LPC1769

Is it possible to connect multiple RC663 reader chips to different UARTs in LPC1769 using the Reader Library

Thank you

Hello,

The examples of the NFC Reader Library are for SPI communication. So the customer can't use the NFC Library via UART.

Have a nice day.

Thank you

But there are parameters in the library

PHHAL_HW_BAL_CONNECTION_RS232

PHHAL_HW_BAL_CONNECTION_SPI

PHHAL_HW_BAL_CONNECTION_I2C

Doesn't this mean that I can use the reader library with RC663 connected via RS232?

Hello,

Yes, RC663 can supports RS232.

Please find more information as the link.

But the library supports SPI. If the customer needs RS232 and needs to design it themselves.
