We're trying to get a real-time graph of the PID system we're working on. Currently, we're using Hyperterminal to log the data sent back over the program port, and then importing it into Excel for graphical goodness.

I'm open to any suggestions on how to make this real-time. I was looking into LabView and getting horribly confused; anyone have any good tutorials on this?

All I really need is something like the UNIX read/write functions; from there, I can hack up a graph in SDL or something. So I'd be perfectly happy with a C serial port interface tutorial.

Any other teams doing this?

Thanks!
