INNOVATIVE DIGITAL TELEPHONE ANSWERING DEVICE (DTAD) SOLUTION USING A LOW COST DTAD CHIP FROM TEXAS INSTRUMENTS (MSP58P70)

摘要

This paper presents a new implementation of a Digital Telephone Answering Device (DTAD) software on a low cost microcontroller from Texas Instruments (MSP58P70). We present our Three Layer Software Architecture, and the state machine implementation of the top-level executive code. This implementation makes the code quite easy to easy-to-follow-and-modify.
