Graphical display

andy g said:

It works as it should but when working with the graphical display, the program does not work. I just hear beeps at the output, hear beeps when I hit refresh the graphical display, the graphical display does not update real time, and the input and output addresses of the code give me nonsense.

As you noted, the graph does not update in real-time. When you refresh the graph, it will HALT the target momentarily so a memory read can occur to update the graph. That is why your program is behaving incorrectly, because of the intrusion.

If you are using a device that supports real-time mode (like 28x), you can enable it so CCS can make non-intrusive accesses to memory.

for more information on real-time mode, see:

Thanks

Ok it is running on polite real time but I am still getting nonsense.

I am using the OMAP L137 EVMC6747

this inout.c file was generated in the source library

When I graph the addresses of the ADC and DAC (&inout_P.DAC_p1, &inout_P.DAC_p2, etc) I still get the same nonsense. Below are the time and freq domain graphs of address &inout_P.DAC_p2 and the graphs do not change when I speak into the microphone input. I've checked all the addresses in the code and every output is similar, if not the same to these. 

I am not good at coding and using this as a method of debugging. 

What am i doing wrong??

can someone help
