4.4 Displaying Graphs

If you ran the program now, you would not see much information about what

the program was doing. You could set watch variables on addresses within

the inp_buffer and out_buffer arrays, but you would need to watch a lot of

variables and the display would be numeric rather than visual.

Code Composer Studio provides a variety of ways to graph data processed

by your program. In this example, you view a signal plotted against time. You

open the graphs in this section and run the program in the next section.

1) Choose View

→

Graph

→

Time/Frequency.

2) In the Graph Property Dialog, change the Graph Title, Start Address,

Acquisition Buffer Size, Display Data Size, Autoscale, and Maximum

Y-value properties to the values shown here. Scroll down or resize the

dialog box to see all the properties.

3) Click OK. A graph window for the Input Buffer appears.

4) Right-click on the Input Buffer window and choose Clear Display from the

pop-up menu.

5) Choose View

→

Graph

→

Time/Frequency again.

6) This time, change the Graph Title to Output Buffer and the Start Address

to out_buffer. All the other settings are correct.

7) Click OK to display the graph window for the Output Buffer. Right-click on

the graph window and choose Clear Display from the pop-up menu.
