9.4 DSK Implementation in C
To achieve higher performance real-time spectrum analysis, we need to transition to a
frame-based C program running on the DSK. However, we ideally want to view a live plot
of the spectrum on the monitor of the host PC, which introduces an additional programming
challenge. We have a general idea of how to program an FFT from Chapter 8, but how
does the spectrum information get passed from the DSK back to the PC, and plotted on
the monitor?
We could use some of the built-in capabilities of Code Composer Studio to do this,
such as inserting a probe point at the appropriate place in the DSK
