The Code Composer Studio (CCS) application provides an integrated environment with the following capabilities:

Integrated Development Environment (IDE) with an Editor, Compiler, Debugger, Project Manager, Profiler, etc.

C/C++ Compiler, Assembly Optimiser and Linker (code generation tools).

DSP Simulator. Real-time operating system - RTOS (DSP/BIOS™). Real-Time Data Exchange (RTDX™) between the Host

and Target. Real-time Analysis and Data Visualization.

You can clear the previous configuration by selecting the configuration you wish to clear and clicking the clear button.

Next select a new configuration that you would like to add:

Select the C6x11DSK - Port x - y Mode. The port number, x, and port mode, y,

depend on your PC setup.

7

If you do not know your configuration then you can select it automatically using the “Configure C6x11 DSK” Utility.


8

Finally save and quit the import configuration dialog box.

Introduction to the ‘C6711 DSK‘C6711 DSKIntroduction to the ‘C6711 DSK‘C6711 DSK

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.

Sono dispositivi logici programmabili e cancellabili. La programmazione permette ai CPLD di simulare un generico circuito

digitale di complessita' non elevata. A differenza delle FPGA le CPLD mantengono la programmazione anche quando non sono

alimentate perché contengono delle memorie non volatili. Vengono usate per applicazioni particolari dove sono richieste alte

velocita' o bassi costi o funzionalita' di glue logic overo di interfacciamento tra due dispositivi complessi.

Laboratory Exercise:DSK Hardware Setup


(1) Connect the following cables: Parallel port. Audio cables.

(2) Connect the power and observe the Power On Self-Test (POST).(3.a) If using the DSK6711 Configure and test the DSK with the utilities shown below:

33

(3.b) If you are using the DSK6713 or DSK6416

Use the Diagnostics Utilities show below:



34

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.
