Hello,
I’m trying to use NFC shield ver.1.0 with official Arduino WiFi shield. I have what looks like conflicting SPI initialization - if I run NFC initialization after Wifi, NFC works and WiFi doesn’t. If I change the order of the initialization, WiFi works and NFC doesn’t. Any suggestions on how to fix this?
Thank you,
Oleg.
Hi,thanks for sharing. We will take it into consideration.
I’m currently trying the same as in this blog and I’m kinda unexperienced with arduino. I have a arduino mega 2560 and added both a wifi shield(official) and a nfc shield(V2.0) on top of it.
I removed the wifiled in the WIFI library, and swapped the path from SS->10 to SS->9. I then edited the PN532.cpp file according to the link above and I did the hardware modifications as it is done in post 2.
Now when I use either shield on it’s own on top of the arduino, they both work flawlessly. Only when I stack the 2 shields together on the arduino, only the Wifi shield seems to function.
In order to test if the shields work I run the provided scripts. For wifi this is the script that scans the available networks, for NFC it is a script that reads the targetID.
Does anyone know how I can fix this, as at the end of the guide I still get
‘Hello!
Didn’t find PN53x board’
Thanks in advance
All right
