RC522 clock speed

Hello,

I'm using this library to read a RC5222 RFID reader

Now, my question is, how do I change the SPI clock, to be a lower frequency?

Anyone had to change it and have a solution?

If none, I could change the source, but I was looking for a solution in code.

Thanks.

It's hard-coded in the library, you will have to edit MFRC522_SPICLOCK in MFRC522.h

OK, thanks for the replay.

At least it's easy to change the source of the library.
