Example Programs

Example programs are included with the ADSP-2181 EZ-KIT Lite to
demonstrate various capabilities of the evaluation board. These programs
are installed with the EZ-KIT Lite software and can be found in
alDSP\218x\EZ-KITs\2181\Examples
provided with each example for more information.
#
Do not run more than one ADSP-2181 EZ-KIT Lite session in the
debugger at any one time. You may run an EZ-KIT Lite session
and a simulator or ICE session at the same time or you can open
two debugger interfaces to run more than one EZ-KIT Lite session.

ADPCM

This program demonstrates Adaptive Differential Pulse Code Modulation
(ADPCM) capabilities. ADPCM consists of a number of real-time speech
compression algorithms.

DTMF

This demonstration generates Dual-Tone Multi-Frequency (DTMF)
tones, as used in the telephone network for push button signaling. A
DTMF tone is composed of two different single frequency tone, one of
four row tones added to one of four column tones. Thus, a full implemen-
tation of a DTMF standard tone generator can generate 16 different tones
(only 12 are commonly used on consumer handsets).

ECHO

This demonstration uses the codec to generate an echo and the four chan-
nel DAC to display the taps of the echo canceller.
