CCS/TMS320F28069: Not possible to graph an array

Part Number: TMS320F28069

Tool/software: Code Composer Studio

Hi,

I am working with Code Composer version: 7.4.0.00015.

I get an analog signal (sinusoidal waveform) via A/D converter and store it on an array of 300 position, defined as double MY_BUF[BUFFER_SIZE], where BUFFER_SIZE is 300.

My issue comes when trying to plot the array in a graph, I get an error message saying double[300] is 16. Only unsigned type of 32/64 bits supported.

I had never experienced this issue before, and I don't get any problems if I just put in graphs the same type of variable of only one position.

Best regards,

Cristina

Hi Ki-Soo, thanks for your reply.

Sadly, I can't show the properties because I get the error message (right click on the name of the variable, then Graph).

I define it as:

double VAC1_BUF[BUFFER_SIZE];

I attach a photo of the error:

Best regards,

Cristina.

Oh, that is interesting. Try manually opening a new graph (Tools -> Graph). You should be able to open a graph that way.

Ok this way I could make it work and I was able to set Dsp Data Type to 32 bit floating point.

Thanks a lot.

Cristina.
