Description

On the client side (laptop) we have been reading the time stamp (via the millis function) as a signed integer. According to the documentation, we should be treating that value as an unsigned long, giving us up to 50 days before it rolls over.

To do this we'll have to account for the fact that a long on the Arduino is 32 bits. Currently we're only sending 16 bits over the wire to the client. Sending 32 bits will slow the data rate down slightly, but I'm not sure yet by how much.

  • Status changed from New to In Progress

I updated the Java code last night to account for this. Since the Arduino Wiring code has been updated as well, I think this issue should be moved to "feedback" for testing.
