i foolishly posted this in the Bar, for some odd reason. the library works with the RDM630 125Khz reader from eBay, like THIS. the intendid use is to match the RFID tag ID from the RDM630, convert it from hex to a unsigned long, and match it against a provided list of stored numbers.
it is very quick and dirty, and i mainly wrote it because i needed it for my alarm project. if anybody has one of those readers, feel free to test the code, beat it into submission, and let me know how i could make it better.
it is located on my GitHub.
i have tested it to work, in optimum conditions. Known issues:
- if the sketches other programming is blocking, then the serial data will lose alignment.
- it does use the dreaded String object.
