Brett,
This GUI has been awesome for playing with the PID library more productively. I am now trying to record some data sets and run them through some system ID code in Matlab so I can do model-based gain selection. (And then I can use it to control the temperature of my mash for homebrewing =)
I am finding that when I give an output file name to the frontend code, it creates an empty file but never writes anything to it. I was able to fix the problem by adding output.flush() immediately after the output.println(). Is there a way to cleanly close the frontend? I didn't see an output.close() or any other wrap-up stuff, so I'm wondering if anyone has been using the write to file feature.
Thanks!
