DOCUMENT LAYOUT
This user’s guide describes how to use the dsPIC33F DTMF Detection Library as a
development tool to emulate and debug firmware on a target board. The manual layout
is as follows:
•
– This chapter explains the basic concepts to help you
implement the dsPIC DSC DTMF Detection Library in your application and
discusses the principle of DTMF tone detection.
•
Chapter 2. “Configuring the Analog Front End (AFE)”
– This chapter
describes the Analog Front End (AFE) on the dsPICDEM.net™ Connectivity
Development Board that provides a programmable line interface to support global
telephone line interface requirements.
•
Chapter 3. “Application Programming Interface (API)”
– This chapter lists and
describes APIs available in the stand-alone dsPIC DSC DTMF Detection Library.
•
Chapter 4. “DTMF Detection Demonstration”
– This chapter analyzes a
sample application program that demonstrates the key functionality of the dsPIC
DSC DTMF Detection Library.
•
– This appendix provides information about drivers used
with the dsPIC DSC DTMF Detection Library.
