9.3 RTDX USING VISUAL C
++
TO INTERFACE WITH DSK
Two examples are provided to illustrate the use of RTDX with Microsoft's Visual
C
, one of which makes use of MATLAB's functions for finding and plotting the
FFT magnitude (not for the RTDX interface). Three projects in Chapter 10 (DTMF,
FIR, and Radix-4 FFT) make use of RTDX with Visual C
++
++
to obtain a PC-DSK
interface.
Example 9.7: Visual C
-DSK Interface Using RTDX for Amplitude Control
of the Sine Wave (

++
This example illustrates the use of RTDX with Microsoft Visual C
. The applica-
tion running on the target DSK generates a sine wave. A procedure follows to illus-
