Building is OK, not working.

Enabled RC522_DBG, still debugging is like hell. Sorry to bother, I compiled the code on RPi3 Model B, there is only Timeout printed on terminal. Tested MFRC522 module with python, SPI-py, etc. It seems it is working, I do not know how MFRC522 module accepting Raw SPI writes, how to know it is actually communicating? MFRC522 responding on SPI ? or Do we need to check registers?

How did you solve this? I'm actually seeing the same thing and the answer isn't obvious to me haha 😁
