Hi all and Happy New Year. I am working on data recorder. I created telemetryBox (on parallax propeller). It collects 13 parameters from different sensors. It sends it via xBee. I wrote Perl script to collect data from USB. Also I wrote using Tk nice display which schows data in label form. But connecting these two seems to be a problem for me. The way I have done it is not nice - data from telemetryBox via my Perl program is written into data.txt file. From that file my Tk display program gets the data and shows it. Is there any other, cleaner way to do it?? Also want to change background color in label showing values. Let say voltage above 5V - green background, 4-5V yellow, <4 red. So dynamic change of the color of label would be nice. Thanks like always Robert
