Hi,
I am using Lazarus on Raspberry Pi (raspbian)
I want to use the RFID card reader/writer RC522.
Do you have an example how to use it with Lazarus please ?
All library and example found use Python.
Thank you
Serge

On the net I can see that Mifare MFRC522 uses SPI. If that is the reader you have, then there are more then one way to access SPI from FPC on Pi:
http://wiki.freepascal.org/Lazarus_on_Raspberry_Pi
http://wiki.freepascal.org/Hardware_Access
http://wiki.freepascal.org/Raspberry_Pi_-_SPI
On this page you can find RC522 datasheet and Arduino library with example code:
https://playground.arduino.cc/Learning/MFRC522
It would be much easier to adapt Arduino code then Python code. If you don't speak C then datasheet will be your best friend (after logic analyzer, of course :-).
