Hi Ben

I used the DSP Sine wave generator and the XYChart. Both are working nice.

But the DSP Input CSV I can not understand how. I have a file with coma separated CSV file but no way to show it on the XYChart.

Hi Stefan,

Thanks for letting us know I have found some problems with the component and I beleive it is fixed and working correctly now.

Here's a quick example of how I was driving it.

I did notice that your data goes slightly higher then a signed int can store? -32768 to 32767 and so if you're using a signed int like I am then you get an overflow.

Let me know how you get on.

Hi Ben

Yes the csv had wrong data. I made a dsp2.csv.
It's working very nice now.

regards

Stefan
