HSP45116 Daughter Board

The HSP45116-DB is a daughter board designed to mate with the HSP-EVAL for rapid evaluation and prototyping of the HSP45116 Numerically Controlled Oscillator Modulator. Together, the board set provides a mechanism to evaluate HSP45116 operation using IBM PC As shown in Figure 1, the HSP45116-DB maps the input, output, and control signals of the HSP45116 to three 50 pin headers. These headers mate with connectors on board the HSP-EVAL to interface the HSP45116’s various I/O and control signals with the HSP-EVAL’s data busses. This interface establishes a path for PC of the HSP45116-DB via the HSP-EVAL.

An IBM PC controls operation to the HSP45116-DB/HSP-EVAL board set. The software package provides the user with a DOS command line interface and graphical user interface for daughter board I/O and control. Since the software supports data acquisition from the HSP45116, software based signal analysis may be used to quantify part performance.

The HSP45116-DB is a 6 layer printed circuit board which comes populated with one HSP45116GC-25. The PC based software required to control the daughter board via the HSP-EVAL is also provided.

HSP45116-DB

Getting Started

This section describes the initial evaluation system setup for the HSP45116-DB and HSP-EV AL board set. The system setup consists of mother/daughter board assembly, software installation, and system test to verify proper operation of the board set.

Assembly

The evaluation board set is assembled by mating the HSP45116-DB daughter board with the HSP-EV AL motherboard. This is accomplished by inserting the header pins sticking through the bottom (solder side) of the daughter board into the three 2 x 25 pin connectors on the motherboard. Proper alignment requires that the J1, J2, and J3 headers on the HSP45116-DB mate with the J1, J2, and J3 connectors on the HSP-EVAL. A moderate amount of force is required to seat the header pins in the motherboard connectors.

HSP45116-DB

As part of the initial assembly , the HSP-EVAL and HSP45116DB 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, but the respective configurations are e xamined hereforcompleteness. The motherboard'sdefaultconfiguration is realized by inserting jumpers into the HSP EVAL'sJ4 jumper field as shown in Figure 2 (see the HSP-EV AL User’s Manual for more detailed information). The default configuration for the HSP45116-DB requires jumper placement across the Configuration Jumper Fields A and B and the J3 Control Header as shown in Table 1.

Before using the board set with the supplied software, pow er must be supplied to the boards, and the HSP-EVAL must be connected to the parallel port of the target PC. Pow er is provided totheboardsbyconnectingtheV the J6 header on the HSP-EV AL to a standard 5V±5% supply. As an alternative, power may be supplied through the HSPEV AL’s 96-Pin DIN connectors. The HSP-EVAL is connected to the target PC by connecting the HSP-EVAL’s 26-PIN shrouded header 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 HSP45116-DB software (NCOM-SOFT) and interface with the ev aluation board set must meet the following requirements:

- IBM PC/XT/A T, PS/2, or 100% compatible with a minimum

of 640K of random access memory (RAM) (NCOM-SOFT does not require extended memory)

- At least 200kB of free disk space on your hard disk

- DOS Version 3.0 or higher

- One parallel port with 27 Pin D-Sub connector

Software Installation

The distribution diskette contains a program called INSTALL.EXE which installs the NCOM-SOFT software onto the target hard disk.

you are installing NCOM-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:

JUMPER CONFIGURATION

FIELD B

The INSTALL program downloads the NCOM-SOFT programs, NCOMCTRL and NCOM_CMD, to the NCOMSOFT subdirectory on the target hard drive. In addition, a subdirectory called NCOM_CHK is created into which ﬁles used to perform functional veriﬁcation are downloaded.

Modiﬁcations to AUTOEXEC.BAT

To run the NCOM-SOFT programs, DOS must be able to ﬁnd the executableﬁles.To ensure that DOS can always ﬁnd the NCOM-SOFT executables, modify the search path to include the location of the NCOM-SOFT directory. For example,iftheNCOM-SOFTprogramsareinstalledondrive C: in a subdirectory called \NCOMSOFT, add the following

HSP45116-DB

line to the end of the existing Path command in the AUTOEXEC.BAT ﬁle:

;C:\NCOMSOFT

If your AUTOEXEC.BAT ﬁle does not contain a PATH command, add the following command to the ﬁle:

PATH=C:\NCOMSOFT

Reboot the PC so that the search path changes will take effect.

System Test

Test software is provided to verify operation of the HSPEVAL and HSP45116-DB board set. Prior to performing the system test, it is assumed that the evaluation board set has been assembled and conﬁgured as described above; power has been applied to the board set, and the 26-Pin shrouded header on board the HSP-EVAL 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

CD C:\NCOMSOFT\NCOM_CHK <Enter>

Run the system test software by typing:

NCOM_CHK <Enter>

The NCOM_CHK.BAT batch ﬁle makesuseoftheCommand Line Interface (see Command Line Interface Section) to initialize the evaluation board set; clock a data vector through the HSP45116-DB, 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 set. If the ﬁles match, the assembled board set passes operational veriﬁcation.

the user should answer NO to the COMP command prompt to compare additional ﬁles.

NOTE:

HSP45116-DB Control Panel Software

The HSP45116-DB Control Panel is a graphical user interface for controlling the operation of the HSPEVAL/HSP45116-DB Board Set via an IBM PC or compatible. The control panel, as shown in Figure 3, supports loading the HSP45116's frequency, phase, and timer accumulator conﬁguration registers, as well as setting the state of various control inputs. In addition, the control panel is used to specify ﬁles which serve as a data source fortheHSP45116'sRIN0-15andIMIN0-15inputsanda data sink for the RO0-15 and IO0-15 outputs. Operation of the control panel software is dependent on the clock source provided to the HSP45116-DB as speciﬁed in the clock select portion of the control panel. The HSP45116-DB Control Panel is invoked by typing:

NCOMCTRL <Enter>

Port Conﬁguration

Communication between the Control Panel software and the evaluation board set requires that the software kno ws which of the PC'sparallelports isbeingusedf orcommunication with the HSP-EV AL and which board address the HSP-EVAL has been configured for . The default configuration assumes that LPT1 is being used and the HSP-EV AL has been configured for a board address of 0. The P ort Configuration can be inspected by opening up the port configuration window using the F9 function key. As shown in Figure 4, the window displays the av ailable parallel ports and their addresses. Also displayed are the current port and HSP-EVAL Board address being used by the Control Panel software.

The NCOM_CHK system test assumes that the LPT1 printer port is being used for communication with the HSP-EVAL. If another printer port is used, the Command Line Interface, NCOM_CMD, must be used to conﬁgure the software for using the other port (see NCOM_CMD’s PC and P# command).
