more channels

[jiqiu]

Hi,

I have a NI-SCXI-1600 USB DAQ with SCXI 1520 strain analog input (40 channels).

In my project, I have to use one channel(a0) to do readings in the beginning. Later I have to use another  channel (a1) to start a new reading while keep the previous going.

I wrote a program, see attached. I start the first readings, then stop it when I add new channel to start a new readings. The problem is when I restart it, the readings of fisrt channel become zero. It does not work. What is wrong with my program?

Also the way I split the array (it will be 37D array since I will use 37 channels) looks ugly. Do you have some good suggestion?

Hello Fay,

The other forum seems like it already posted an answer.
If you need to add channels on the fly, you will have to perform an acquisition of all the channels and disable the ones that are not selected. Please post back to your thread or to the duplicate one.
