Default Tube Tracer

I am thinking of a follow-up webzine article to the micro-processor controlled tube tracer in AX. A lot of tubies, it seems, don't want to get near a microprocessor. Thus I got a couple of USB ADC/DAC cards from National Instruments/Measurement Computing and have been busily writing the code. Here's a screen-shot of the layout for the front panel. Since the flow-chart was already written, it isn't going to be a lot of work to finish it up.

I am open to suggestions. The programming is in Softwire which is a tool package for VB.

Hey, I like!

I was thinking of one in Perl/Tk or Tcl/Tk, but too lazy to work on the hardware interface

That looks awesome! I wondered if there was an opportunity to make use of these cards for a tracer. One suggestion, permit saving data in .csv or tab-delimited form, something compatible with OpenOffice, Gnumeric, etc.. Do you have a link to that webzine article?

Softwire has a "Write Excel" and "Read Excel" functions, as well as "Write File". I hate parsing data files -- goes back to the Lotus 1-2-3 and Quattro-Pro days.

Dang (can I say that here?) Wordstar then? Oh well, both Oo and Gnumeric have greatly improved Excel compatibility as long as the files don't make heavy use of programming components and macros.

Please make it compatible with Lotus123... Beware that you will need to add some smoothing to the curves to overcome A/D and D/A monotonicity failures (SOFIA didn't do that).

these are the curves I got from the AX article -- smoothing may make it look somewhat nicer --
