Adafruit pn532 Breakout Board Pi 4

[SoftwareElec]

Hi all,

I am trying to get NFC up and running on Raspberry Pi 4 using the Adafruit PN532. I have a couple of questions..

1. Has anyone got the definitive wiring protocol for SPI to Raspberry Pi 4. I must have come across 3-4 different ways.

2. I have followed the below link:
http://wiki.sunfounder.cc/index.php?tit ... spberry_Pi

I followed this all the way to the bottom and I get the exact same error as the author describes:

Code: Select all

nfc-list: ERROR: Unable to open NFC device: pn532_spi:/dev/spidev0.0:500000

However, changing from 500000 to 50000 appears to make no difference (this was the fix outlined for the above error).

If anybody could help me with these questions it would be greatly appreciated.
