Need help writing callback for Python streaming example

Post by Paul Breneman » Tue Jul 22, 2014 2:46 pm

For more information please see this thread in this forum section: http://www.picotech.com/support/topic14069.html

A single channel (at a slow rate) would be enough for a simple example (no advanced features needed).

Another thread is also related: http://www.picotech.com/support/topic14123.html

Thanks! :)

Note to forum moderators: My previous message disappeared when I edited it! This forum sure is slow due to moderation of every message.

Thanks Martyn! My post count stays at zero so I guess I'll always be moderated? Not the biggest problem I'm dealing with... :)

Thanks again Martyn! I'm making progress. I found out why I got an exception in Delphi and Python after calling RunStreaming (which returned OK). It was because I had the third from the last parameter (downSampleRatio) set to zero instead of one. I've also made a little progress on the callback (but things still don't work). Here is my latest code: http://ctrlpascal.com/ps5000acon4.zip

My messages now show up right away.

I did get streaming working with Delphi. I'll spend a bit more time trying to get it working in Python, but if you (or anyone) has any suggestions I'd appreciate them. I hope I can post an improved Python example in the next day or two.
