Step 28PC Software
Shown below is the PC based scope GUI, displaying both scope channels. The software is available for free download from the oscilloscope homepage
You control all functions of the scope from this software: Channel level scaling and offset, timebase, trigger, averaging, etc. I made an effort to keep the layout simple and user friendly, and at the same time fast to operate. You be the judge if I succeeded - different people have different preferences of course. Good suggestions for improvements are always welcome.
You can make measurements on the traces using the cursors (here: amplitude and frequency - see green cursors in the display and status bar at the bottom).
The screen refresh rate is quite acceptable, I get about 7 frames/sec with a single channel turned on, and 4.5 frames/sec with both channels turned on (record length 250 points in both cases). There is a new version of the Picaxe microcontroller announced to be released some time in the future (but not sure when exactly) which will roughly double those numbers - then the display will become really fluent.
