Stabilizing an incoming string for reliable monitoring

[Hobbs23]

Hello Everyone

The way my receive is set up will hopefully be temporary because the Engineer is adding a termination character.

The problem I am having does not seem to be related.

The problem is that the output of the concatenate strings function is jerky, and does not seem to maintain sync with the indicator. The numeric string will be scrolling up, and then jump around the indicator display disconnecting from the normal format. When monitoring the data, the result indicates a discontinuity in the data at the same time giving skewed results.

Meanwhile I connect a set of 13 indicators at each of the Shift Registers, and array them side by side, and the effect is a marque scrolling of sorts. Whenever the above is jumping around, this remains rock solid, and very readable.

How do I grab the information in a stable format both to the eye, as well as to the sorting functions?

What instrument are you trying to communicate with?  There has to be some protocol you can follow to get your messages out.

Thanks for your response crossrulz

It is a new Signal Generator in R&D. The software it runs on, is as incomplete as my Labview skills ;). The RF is what is completed first, and then the rest is imagineered. I just requested a termination character with all external comms. Right now they are using CR and LF as formating for a display, so It may take a bit for him to decide.

On another note altenbach is carving me a new understanding of how not to do what you see above. As soon as I get rid of the bad programming, I will repost what It looks like here.
