HSP50016-EV

Getting Started

This section describes the initial evaluation system setup for

the HSP50016-EV evaluation board. The system setup

consists of the evaluation board, software installation, and

system test to verify proper operation of the board.

Assembly

As part of the initial assembly, the HSP50016-EV must be

provided with the default jumper configuration to ensure

proper operation with the system test software. Each board

leaving the factory is supplied with the default configuration

as shown in Figure 1.

Before using the board with the supplied software, power

must be supplied to the board, and the HSP50016-EV must

be connected to the parallel port of the PC.

t Power is provided to the board by connecting the wall

mount power supply provided to connector J2. As an

alternative, power may be supplied by a standard 5V ±5%

supply through the J3 header or the HSP50016-EV’s 96

Pin DIN connectors P1 or P2.

t The HSP50016-EV is connected to the target PC by

connecting the HSP50016-EV’s 26 Pin connector J1 to the

PC’s parallel port using the supplied ribbon cable.

System Requirements for the Evaluation Board

Software

The PC system targeted to run the HSP50016-EV software

(DDC-SOFT) and interface with the evaluation board must

meet the following requirements:

t IBM PC/XT/AT, PS/2, or 100% compatible with a minimum

of 640K of random access memory (RAM) (DDC-SOFT

does not require extended memory)

t At least 250kB of free disk space on the hard disk

t DOS Version 3.0 or higher

t One parallel port with 27 Pin D-Sub connector

Software Installation

The distribution diskette contains a program called

INSTALL.EXE which installs the DDC-SOFT software onto

the target hard disk. Note: The steps in this section assume

you are installing DDC-SOFT from a diskette in drive A: onto

a hard drive C:. If a different configuration is used, substitute

the letter of the drive where the diskette is located for drive

A: Substitute the letter for the hard drive for drive C:.

To start the installation program:

Make sure computer is on and the DOS prompt is displayed.

t Type: C:<Enter>

Create a subdirectory to contain the DDC-SOFT Programs

by typing:

t MD \DDCSOFT <Enter>

Change current directory to the DDCSOFT directory

t CD \DDCSOFT <Enter>

Start the installation process by typing:

t A:INSTALL <Enter>

The INSTALL program downloads the DDC-SOFT programs,

DDCCTRL and DDCCMD, to the DDCSOFT subdirectory on

the target hard drive. In addition, a subdirectory called

DDC_CHK is created into which files used to perform

functional verification are downloaded.

Modifications to AUTOEXEC.BAT

To run the DDC-SOFT programs, DOS must be able to find

the executable files. To ensure that DOS can always find the

DDC-SOFT executables, modify the search path to include

the location of the DDC-SOFT directory. For example, if the

DDC-SOFT programs are installed on drive C: in a

subdirectory called\DDCSOFT, add the following line to the

end of the existing Path command in the AUTOEXEC.BAT

file:

t ;C:\DDCSOFT

If your AUTOEXEC.BAT file does not contain a PATH

command, add the following command to the file:

PATH=C:\DDCSOFT

t Reboot the PC so that the search path changes will take

effect.

System Test

Test software is provided to verify operation of the

HSP50016-EV Board. Prior to performing the system test, it

is assumed that the evaluation board has been assembled

and configured as described above, power has been applied

to the board, and the 26 Pin Connector J1 on board the

HSP50016-EV has been connected to the parallel port of the

target PC via the supplied cable. The system test is initiated

by the following:

Change the current directory to that which contains the

software required for the system test by typing:

t CD C:\DDCSOFT\DDC_CHK <Enter>

Run the system test software by typing:

t DDCCHK <Enter>

The DDCCHK.EXE batch file makes use of the Command

Line Interface (see Command Line Interface Section) to

initialize the evaluation board, clock a data vector through

the HSP50016-EV, and store the output to a file. The output

file is then compared, using the DOS command COMP, to a

file containing a set of vectors generated by a properly

functioning board. If the TEST_IN.DAT and TEST.OUT.DAT

files match, the assembled board passes operational

verification.
