Hi Folks,

Has anyone used one of the NFC readers (RC522 or PN532) with Processing for Pi? They both have SPI interfaces, which should work with the Pi, but without a library I’m in over my head looking at the low level docs for SPI communications. There are libraries for this readers in both Arduino and Python - how feasible would it be to port one for Processing for Pi?
