Hi Colin,
Excellent! Sounds like an interesting application. Does it have to be TEA encrypiton? I ask in case you haven’t coded it yet, since we have a Base64 encoding code available for download, (see this example).
In any case, when you enter your values as decimal numbers, PAC Control will try to “help” you by doing that range check, assuming you care about sign, which you don’t. Just enter them as HEX values and you should be fine. For example, if you wanted the max 32-bit value of 0xFFFFFFFF and tried to enter the decimal equivalent: 4,294,967,295 you’d have a problem. But if you just use that 0xFFFFFFFF you should be good to go.
BTW, I ask about Peer-to-Peer because I’m currently working on another example that would let you Get or Set a variable from one controller to another, WITHOUT having to use the Scratch Pad. Would that be of interest to you?
Thanks,
