All,
·
I am trying to connect the read tag number to a variable that I can use in IF THEN statements.· I am not understanding very well how you can read from a table of known tags and go to different areas of your program.
·
Any ideas on how to do this?
·
Thanks

    Tim,

    Go into you PBASIC file and look for LOOKUP or LOOKDOWN, much better then a if..then..else statement!

    There is a demo/sample program for the RFID Reader that has a lookup table for names and tags.· Studying that should give you some ideas.· Take care.

    I looked at the sample in great detail.· The trouble I am having is trying to figure out how to connect the read tag to a variable that can be used later in the program.

    Thanks for the help.

    Thats exactly what I was looking for.· Thanks very much for the program piece I was missing.· I am going to use different tags on my Christmas train to set of different sounds as the train travels down the track.
