Other Parts Discussed in Thread: TMS320C5515

I have configured the ADC and its working fine. I save the ADC-data into an array.

The array has 1024 points. I want to plot the array elements. So that i could confirm that the ADC has aquired it properly.

I saw a grpah tool in CCS. But I am not able to configure get it working. I am using CCS Vr4. If someone could tell me how can I import the

array values into a Matlab workspace, I can plot it there. Is it possible ????

    Hello Anand,

    This post covers a similar issue with links to the tutorial for using the graph.

    One way to get data into matlab would be to use a printf loop of the array with a comma between each value to a terminal program and save it.  Then in matlab you would import it as a comma separated data file.

    Thanks,
