soundtec:
Here's Fremens last few versions ,

soundtec:
Ive just downloaded an old version of picoscope for free to try and see if it will allows waveform selection from a library usable with the FY6600.

drawing a waveform could take ages ,surely theres a repository for such waveforms and you could have an endless variety 

precaud:
I downloaded the software again (this time from Google Drive), reinstalled, ran, and got the same error as before. It loads into the "Extraction" Window, but when loading it into the Waveform Window, it bombs (see attached). IIRC, this software is Visual Basic code. Maybe it needs a later version of VBRUN than I have?

I then installed the 0.7 version of fremen67's software (thanks, soundtec). It loaded the file directly into the Waveform Window and uploaded it to the 6800 fine (I think, I haven't looked at the output yet).

To verify the data is correct, I tried loading the file into the Text Window (using Loading Area 2) so I could examine the data and see if it was being converted correctly. This window does not work correctly, it displays all values as 0, 1, or -1. I turned off "auto-resize data", with the same results. I then tried sending the data to the 6800 (loading Area 2 goes to ARB2 waveform). The waveform sent was the same array of 0, 1, and -1 values. So loading into the Text Window destroys the data, and there's no way to verify that the data values are being converted correctly.

I never could understand what the Text Window was supposed to be doing - even fremen's version seems to just convert all the data points to integers (try loading the sinc-pulse file I uploaded earlier, and you'll see the waveform in block form with values -1 to 5). 

If you upload to Loading Area 2, won't you overwrite the factory-stored square wave there?  The empty loading areas are from 64 back to ?? (can't remember offhand).

precaud:
 I looked at the output waveform (with an 8-bit scope) and the data transferred from the Waveform Window using fremen67's program appears to correct. None of the duplicate time data points that I saw before. So this can be a realistic basis to my comparison tests. Thanks for your help in gettin g this sorted out!   :-+
