Detailed Description

Codatex RFID driver.

codatech-rfid.h provides an API for the Codatex RFID sensor. Based on information given on http://www.codatex.com/picture/upload/en/RFID_I2C.pdf and on Stephen Hall and Oliver Graff previous work on this sensor.

Changelog:

• 0.1: Initial release
• 0.2: Partial rewrite by Xander Soldaat to simplify API
• 0.3: Uses new array typedefs instead of structs

Credits:

• Big thanks to Xander Soldaat for giving his work on other sensors's drivers code for ROBOTC.
  (Seriously, I'd have given up without you !)
• Thanks to Stephen Hall and Oliver Graff for their work which made me understand the initialisation need !

License: You may use this code as you wish, provided you give credit where its due.

THIS CODE WILL ONLY WORK WITH ROBOTC VERSION 3.59 AND HIGHER.
