Sharing a VISA refnum between two while loops.

I think this would be the most suitable solution since you only call the visa read / write once at a time, keeping all data buffered and using notifiers. Thanks everyone.

By the way, in the settings of the port (control panel) I recommend setting the size of the receiving fifo buffer equal to 1. Thus, pauses between sending from ~ 50 ms to 3-5 ms decrease. This is due to the fact that the timeout for filling the buffer of the receiving chip is minimized.

Hi Borjomy,

Have you seen my Nugget on Action Engines found here?

I ask because your suggestion is very close to the form of an Action Engine but requires the assistance of the seq frames to make it work right. Action Engines can offer a an approach that is just a little bit cleaner and easier to use.

Just trying to help,

Hi, Ben

Sequence is used here only to press the "Stop" button after stopping all cycles.
