NFC/RFID using SPI with raspberry pi

Post by osoverflow »

Hi! I want to know how to connect the NFC/RFID controller breakout board using the SPI interface instead the serial one.

This because my project uses a printer with that serial pins (RX/TX) and I want to use the reader without an USB to console wire...

Thank you!

I don't know if that's possible. On the Pi, the NFC card relies on the libnfc library. As far as I know, that's serial-only.

I found this:

New in 1.7.0:

Drivers:

* New PN532 over I2C driver, see contrib/libnfc/pn532_i2c_on_rpi.conf.sample

So it should be possible to use i2c, isn't it? but don't know how to wire it.

The R-Pi pinout is here: http://pi.gadgetoid.com/pinout
Attach SDA to SDA and SCL to SCL. Configure the jumpers on the PN532 board for I2C.

This is not something we support. I have no idea whether or not it works, not would I know how to make it work if you have problems.
