This document explains how the EVM Application #3 creates a 2- channel sine wave generator using the 12-bit digital-to-analog converter (DAC) of the Texas Instruments (TI™) TMS320F240 Evaluation Module (EVM). It contains:
An overview that explains how this application functions
- Information on the two modules used
- Information on how to use commands in the debugger environment
- Equations for calculating either the frequency of a sine wave or the displacement value to load into the modulo register of the corresponding sine wave
- Graphics showing two types of interpolation schemes
- Tables showing the phase differences between examples with interpolation and without interpolation
- The C2xx Assembly code that implements the application
