Rust MFRC522 driver

This is a no_std driver for the MFRC522, an ISO/IEC 14443 A/MIFARE reader/writer IC.

This repository is an extension of japaric/mfrc522 and the new home of the mfrc522 crate.

What works:

• SPI communication with the MFRC522
• Anticollision loop
• Select for 4-byte and 7-byte UIDs
• Mifare Classic authentication
• Reading/writing data
• Configurable timeout
• Non-blocking API + support for the interrupt pin
• Mifare Ultralight C 3DES authentication (no support planned)
