Goodbye bytearray, hello hex!

There is a new update on github for the device code, the much needed reading UIDs in hex format. Much needed because that is what the rest of the world does, so it now means-

  • You can check UIDs by scanning a NFC chip with your phone
  • You can order pre-scanned and labelled NFC chips in bulk, and the prescanned hex code will be compatible
  • The spreadsheet looks neater

Pycom also released an update meaning longer (14 byte I think... off the top of my head) UIDs are now supported.

Still more to get done this week!
