2010

Nathan Tomlin based his code on Jens Roesner's code. NOTE: The following description is lightly edited from Version 1.0.0.0 by Nathan Tomlin on Mathworks File Exchange:

I have mainly used code and examples from Jens Roesner here. However, I had to make a few slight tweaks to get it to work for me.

Using Jens' code, I got an error -200088 whenever I tried to create a channel. To get it working, I had to change the initial task handles to uint32([]) which then returned a pointer for taskhandle.

I also had trouble with creating tasks, then losing the taskhandle, and not being able to create the same task because of a name conflict. The solution is to not name any of the tasks - names don't seem to be useful anyway. So all my functions pass an empty string as a name.

Other changes are just cosmetic: Made functions for common tasks to simplify my main code, and put all task handles in structure so easy to clear.

2005

Jens Roesner wrote his scripts (versions 1.0 as of 20 Feb 2005) and published them on the NI forum and his website.
