MFRC522 v1.4 seems to not work

Projects Programming

Hey all,

I tried running the Dumpinfo Example under the MFRC522 examples, but it didn't work. I downgraded the version of the MFRC522 library installed to 1.1.8 (the one used in the old tutorial I was following), and it worked.
I left all my connections the same and only upgraded the library to 1.4.11 for it to stop working. Leaving everything the same and downgrading to 1.3.0, it began to work again.
1.3.6 also worked, but 1.4.0 didn't work.

Just want to find out if it's just a problem with me or if its widespread.

Thank you.

It appears to be a library issue; something likely changed when the library was updated. This is not uncommon. For this reason, I typically store the libraries alongside my sketches to maintain compatibility.
