DAC Software Application
Revision 1.00
----------------------------
Application Summary:
Outputs 4 Sine Waves on the EVM DAC through the channels DAC0, DAC1,
DAC2, and DAC3. Each sine wave is generated through a look up table
and interpolation.
Each sine wave can be controlled independently. By manipulating the
following variables, the frequency, phase, and magnitude of each
sine wave can be changed.
FREQSTEPx - modifies the frequency
MODREGx - modifies the starting point of the sine wave
MAGx - modifies the peak to peak voltage (Q15 value)
where x is 0,1,2,3
The variables can be easily manipulated through a watch window in the
debugger environment.
