@627117717.pr Well, so I have described the first step of using SPI loop back as a way to check out the SPI hardware wiring and software initialization are more or less working OK. The second step is to use python shell commands to import SimpleMFRC522, create an object reader and then write something a read back.
As I suggest in the very beginning, it would be nice if you can compile an answer yourself for your own question, alongside my answer. My answer is Rpi4B buster, yours is Rpi3B+ stretch NOOBS etc etc.
Question: Have you any experience in using the data structure "list"? And do you have any vague idea of "scalable" or "SCALA"? I am now going to do scalable python3 list processing of up to 8 MFRC522 modules (Yes, I have 12 in hand.). In case you could not catch up, I think I would just skip the program documentation, and show you how to use it.
Ah almost bed time! So see you tomorrow. PS - my last appendix gives an idea of how I am "pinging" two modules. (If you have never heard of the term "ping", then you would need a long long time to catch up.
