Demonstration Summary
To demonstrate the functionality of the AEC library, a sample dsPIC33F-based appli-
cation emulating two speaker phones engaged in voice communication is provided with
the library. This software requires the use of two dsPICDEM? 1.1 Plus development
boards (not included with the software license), which are set up as shown in
FIGURE 3-1:

Running AEC Library
Board 1
dsPICDEM 1.1 Plus
Board 2
A speaker and a microphone are connected to dsPICDEM 1.1 Plus development board 1
and are located in proximity to each other. A headset is connected to board 2.
When a person speaks into the headset connected to board 2, the speech signal is
sampled through the on-board Si3000 voice band codec and the Data Converter
Interface (DCI) module of the dsPIC DSC device. The dsPIC DSC device then transmits
the compressed speech signal through its UART1 module and the on-board RS-232
transceiver to board 1.
The dsPIC DSC device on board 1 receives the signal through the on-board RS-232
transceiver and the device’s UART1 module. The dsPIC DSC device then plays out the
signal on the speaker through its DCI module and on-board Si3000 codec.
