Revision as of 20:19, 16 October 2014
Objective
- Get an reduced functionality acnode out there ASAP and add improvements incrementally as they are developed/needed.
- Have a platform that's fexible enough to do other things (power metering, display driving, etc)
Updates
- 5-OCT-2014: Switching to a PN532 chipset reader, had to write a library for energia. issue with not enough current to drive the SSR relay being looked into by tgreer
- 12-AUG-2014: Problem discovered with support for mifare classic cards (old oyster, barclaycard)
- 11-AUG-2014: Ready for integration with the Lulzbot
Specs
Minimal implemnentation.
