I am a freelancer and working on MFRC522 for quite some time.
One thing I wondered was the quality of documents and information around MFRC522 available online.
I was planning to invest some time and prepare certain documentation to bring all information in one document or maybe a few documents.
I am eager to know from you all what and all I can include in the same.
Few things I am planning to add are below
1).Antenna Design Guide.
2).UART And I2C Communication Firmware with MFRC522
3). Schematic Diagram for the MFRC522 as per available boards in market
Thanks And Regards,
