[Tinyos-help] Send Data from Tmote Sky to PC via UART

[Michael Schippling]

I'd have to know more about your application to opine on data structures,
if it's just image data then a one-D array seems reasonable. What didn't
work about your 2D array?

You are probably looking at the T2 tutorial which I don't have. If it's
about using EEPROM storage on the mote then that's probably the thing.
But also not that the EEPROM has a somewhat limited number of write
cycles which you need to consider in your speeds and feeds calculations.
