Chapter 3, Slide 10
Check that the DSK is connected properly
and powered up.
Check if the port address and mode is correct
(See Slide 7).

Introduction to the ‘C6711 DSK



Chapter 3, Slide 11
The ‘C6711 DSK provides a powerful,
low-cost development environment.
The DSK comes with CCS code
development tools (does not include the
simulator).
A laboratory at the end of this section
takes you through the DSK setup and
shows you how to run the confidence test
to check if it is working correctly.

Use the Diagnostics Utilities show below:
Chapter 3, Slide 33
Dr. Naim Dahnoun, Bristol University, (c) Texas Instruments 2004
Laboratory exercise: DSK hardware setup
Notes:
 The SDRAM may take a while due to the large
amount of SDRAM on the ‘C6711 DSK.
 The CODEC test performs two operations: (1) a
1kHz tone output, and (2) an audio input to output
loopback. You must have a speaker connected to the
the output jack to hear the test.
 If the confidence test fails:
(1) Remove the power and parallel cable from the DSK.
(2) Reset your PC.
(3) Reconnect the power and the parallel cable.
(4) Invoke CCS.
