Creating Serial Digital Waveform Data

[kdowty]

All,

I have to create a serial interface for a project I am working on.  This serial data is being created from an array of 16 bit integers being read in from an XML file.  I have had the darndest time figuring out how to turn this 16 bit integer into a single line serial data stream.

I thought this would be an easy task, and I was surprised that this question hasn't been asked and answered already in this forum.

With the help of a NI FAE that rolled through town (Thanks Justin!), we came up with this solution.  I thought I would post it here to aid future users.

The real problem I had to work around is that the digital waveform creation object wants a 2D array to populate waveform.  I still don't have any idea why a 2D array is necessary.

Anyway, this is my solution.  I hope people find it useful. And if there is a better way than converting from U16 to Boolean to Array of 1:0's to 2D array to WFM, I would love to see it.

This?

Although changing the mode from LSB to MSB doesn't seem to work...always stuck in LSB mode....bug maybe?

And you need 2D data because row = sample value and column = signal.

Thanks Bill. 

I understand
