NFC v2.0 with arduino Leonardo eth

[kavi]

Hey everyone,

sorry for hijacking this thread, it just fits in nicely. I have had the same issue which was resolved changing this pin assignment. However, it seems the NFC shield and Leonardo ETH’s networking functionality seem to be mutually exclusive.
After

Code: Select all
nfc.begin();

any existing network connection is dropped or cannot be established. I fail to find the reason for that. Explanations greatly appreciated.

Thanks,
o.

Hi,

Both NFC shield and Leonardo ETH uses SPI.This causes conflict in your issue.If you are using NFC enable the 9th pin and disable 10th pin and do the vice versa when you want to use the ETH.

In the example code that we have given in this thread we would have disabled the 10th pin always in the setup function which was exclusively written for NFC shield to work.

Please remove that part of code and include appropriate enable and disabling of pin in the loop function according to your requirement.

Thanks and Regards
