RTDX for Real-Time Data Transfer
The RTDX feature was used to transfer data to the PC host using a sine wave from
a lookup table as input. A single output channel was created to pass to CCS the
input signal, the output of both the loop filter and the DCO, and time stamps. CCS
buffers these data so that they can be accessed by other applications on the PC host.
CCS has an interface that allows PC applications to access buffered RTDX data.
Visual Basic Excel was used to display the results on the PC monitor. Chapter 9
introduced RTDX with several examples using different schemes.
This project was implemented on the C6211 DSK and can be transported to the
C6713 DSK. All the necessary files, including the MATLAB file to test the project,
are on the CD in the folder PLL .
