ADSP-21061 EZ-KIT Lite™ Evaluation System

ADSP-21061 EZ-KIT Lite™ Evaluation System


2.1. Overview

This chapter provides you with the information you need to install your software and the ADSP-

21061 EZ-KIT Lite evaluation board. Install your software and hardware in the order presented for correct operation. This chapter also provides basic board information.

2.2. Contents of Your EZ-KIT Lite Package

Your ADSP-21061 EZ-KIT Lite should contain the following items. If any item is missing, contact the vendor from whom you purchased your EZ-KIT Lite.

The evaluation board contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the human body and equipment and can discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges.

Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Unused boards should be stored in the protective shipping package.

• ADSP-21061 EZ-KIT Lite board

• Power cable with 9V DC power supply

• 9-pin RS-232 serial port cable

• CD-ROM containing EZ-KIT Lite target .dll files, examples, Help file, and utilities

• CD-ROM with VisualDSP++

• CD-ROM (DSP Designer’s Reference) containing DSP documentation

2.3. PC Configuration

For correct operation of the VisualDSP++ software and EZ-KIT Lite demos, your computer must have the minimum configuration shown below.

2.4. VisualDSP++

ADSP-21061 EZ-KIT Lite is shipped with the VisualDSP++ Integrated Development and

Debugging Environment (IDDE), and code generation tools. VisualDSP++ is limited in functionality by the EZ-KIT Lite serial number shipped with this product. The EZ-KIT Lite serial number restricts the VisualDSP++ IDDE to connect only to the ADSP-21061 EZ-KIT Lite evaluation board running the debug monitor via the serial port (no emulation or simulation support). Additionally, the linker restricts you to only 25% (4k words) of the ADSP-21061

SHARC processor’s on-chip program memory space. If you purchase the full VisualDSP++ software suite you will obtain a new serial number from Analog Devices to lift the restrictions mentioned above.

The basic components that are shipped with VisualDSP++ are:

Integrated Development and Debugging Environment (IDDE) — graphical interface for project management, allowing you to set project options, access the code generation tools and view the insides of the DSP and perform debug operations such as read/write memory, read/write registers, load programs, run, step, halt, and more.

SHARC Family Code Generation Tools — C/C++ compiler, assembler, run-time libraries and linker, loader, simulator, and PROM splitter.

Example Projects — Both VisualDSP++ and the ADSP-21061 EZ-KIT Lite are shipped with example projects and C/C++ and Assembly source code that demonstrate various features of the tools and the ADSP-21061 DSP.

2.5. Installation Procedures

The following procedures are provided for the safe and effective use of the ADSP-21061 EZ-KIT

Lite evaluation board. Follow these instructions in the order presented to ensure correct operation of your software and hardware.


2.5.1. Installing the EZ-KIT Lite Hardware

The ADSP-21061 EZ-KIT Lite board is designed to run outside the PC as a stand-alone unit. There is no need to remove the chassis from your computer. To connect the EZ-KIT

Lite board:

1. Remove the EZ-KIT Lite board from the package. Be careful when handling the board to avoid the discharge of static electricity, which may damage some components.

2. Connect the RS-232 cable to an available COM Port on the PC and the ADSP-21061

EZ-KIT Lite evaluation board.

3. Plug the provided 9V-power supply into a 120-Volt AC receptacle and plug the connector at the other end of the cable into P2 on the evaluation board.

The FLAG3 and FLAG2 LEDs will start to toggle. The POWER LED remains on.

If the LEDs do not light up, check the power connections. If you plug a pair of selfpowered computer speakers into the Jack J22 (Output) on the board you will be able to hear a tune.

To configure your board to take advantage of the audio capabilities of the demos:

1. Plug a set of self-powered computer speakers into Jack J22 on the board. Turn on the speakers and set the volume to an adequate level.

2. Connect the line out of an electronic audio device to Jack J23 (Input) on the board. Set jumpers JP6 and JP8 to LINE.

This completes the hardware installation.

2.5.2. Installing VisualDSP++

The EZ-KIT Lite includes the latest evaluation version of VisualDSP++ for the ADSP-

21061 SHARC DSP Family. You must install this software prior to installing the EZ-KIT

Lite software.

Insert the VisualDSP++ CD-ROM into the CD-ROM drive. This will bring up the CD browser.

Click on the “Install VisualDSP++” option. This will launch the setup wizard. When prompted, by the component selection dialog of the installation wizard, insure that the

21061 EZ-Kit Light check box is checked.

Follow this wizard with the on-screen instructions.


2.5.3. Installing the EZ-KIT Lite License

Before the VisualDSP++ software can be used, you must install the license software. To install the EZ-KIT Lite license software follow these steps:

1. VisualDSP++ has been installed.

2. Insert the VisualDSP++ CD-ROM into the CD-ROM drive if it is not already in the drive.

3. Once the browser appears, select the "Install License" option.

4. Follow the setup wizard instructions.

NOTE: Ensure that you have the proper serial number, which is located on the back of the

CD sleeve.

2.5.4. Default Settings

After you have installed the board and utility software, your PC and EZ-KIT Lite have the default settings shown in Table 2-2. You can change these settings through the Settings menu in the IDDE.
