multi chanel read DAQ

[yechielo]

I am a student and use 14bitDAQ for my final project,

I read 3 chanels from 14bit DAQ 2000 samples in 40Hz, how can I separate the info from the DQA by chanels?

I understand you want to separate the channel data into, say, different arrays.  To do this, use the "From Dynamic Data" and choose 2D array of scalars (rows/colums as you want). See attached pictures.

but now i have a new problem, I need to draw 3 grafs of 3 difrent chanel, am i need to spilt the 2D array or can I do it from the 2D array?

thx

You just need to index the array using the array pallet. Then drop on the graph and hook it to the graphs like in the picture.

You can use the aeastet's method to plot on different graphs or if you want all the channel data in a single graph, just connect the 2D array directly to the graph (ensure that the rows are channels).

Hi aeastet ,

Thx for your help, this is exactly what i need to do, i separated the chanels, but where i can find the wave form graph?

see atach

Thx

The Graph is located on the front panel controls. You will have to place the graph on the front panel and then go to the block diagram to hook it up. Look at the attached pictures.
