Lab Exercise 4
DTMF Tone Generation on the 'C542
Read the project documentation of Dominguez and Zuloaga on Dual Tone Multifrequency Generation Using Visual C++ (ELC152-oct2003-07) for information and references regarding standards for DTMF tones in telecommunication systems.
Write code to generate a standards compliant sequence of DTMF tones on the 'C542. You are to generate the sequence corresponding to #d1d2d3d4d5d6* , where d1d2d3d4d5d6 is your 6-digit ID number. Operate the analog interface at 8000 Hz.
Note that the DAC in the analog interface is a 14-bit DAC and that the 2 least significant bits of a 16-bit value sent to the DAC must be zeroed out. Read the TLC320AC01C Data Manual for details.
Be able to answer all questions related to this exercise. During evaluation of this exercise, you must have with you on files or on paper any and all forms of documentation that you would need to show and/or discuss how you went about doing this exercise.
