Introduction

Zilog’s Modular Development System General-Purpose (MDS-GP)
Application Board, ZGENPRP0100MDS, adds a variety of peripheral
interfaces to Zilog’s eZ80Acclaim!
family of MDS-compatible processor modules. MDS-GP is the first of a
series of application boards that makes it easier for developing products
with Zilog

Zilog’s MDS processor modules (MDS-PM) are available as stand-alone
development kits that include a Zilog microprocessor and everything you
need to get started. Adding the MDS-GP board to an MDS-PM develop­ment system provides interface to expand your application development
possibilities.

MDS General-Purpose Board Development Kit

MDS-GP board Overview

The MDS-GP application board is controlled by an MDS-compatible
processor module (MDS-PM). The MDS system interface consists of two
common 60-socket headers (labeled JP1 and JP2 on the MDS-GP board)
that connect to mating pins on the MDS processor module.

The eZ80Acclaim!

and ZNEO

Z16F processor modules can fully utilize the MDS-GP board
features (see Board Features on page 2) whereas Z8 Encore! XP F0822
Series Flash Microcontrollers and Z8 Encore! XP modules cannot use all
MDS-GP board features. The CD-ROM provided with MDS-GP kit
includes sample projects that use many of the board’s features.

For sample project descriptions, refer to MDS General-Purpose Board
Quick Start Guide (QS0045).

Caution:

Caution:

Notes:

Connect only one power source at a time.

•

5 V DC into J14 — The 5 V power supply included with Zilog

MDS-PM development kits can be used for this input to power both
the MDS-GP board and the MDS processor module.

•

9 V to 12 V DC into J25 — The eZ80Acclaim!

with a 9 V DC power supply.

•

12 V DC into RS-485 connector, J4 — This connector provides another

means for supplying power to the board (Battery holder BT1 must be
empty).

•

4 AA cells in battery holder BT1 — Switch S2 present on the top right-

hand corner of the board turns the battery power source ON or OFF.

Ensure S2 is OFF or remove the batteries before connecting
another power source.

1. Do not use the DC input jack on the MDS-PM board when it is

plugged into the MDS-GP board. You must power the system with one
of the MDS-GP power supply inputs.

2. If your application is using the on-board relays, then you must

provide 9 V to 12 V DC into the MDS-GP board or change out the
relays to 5 V parts.

tion. This connector also provides 5 V DC power and a system reset line
(see Figure 5). The chip select control for this bus is generated from PAL
U26 and is programmed at the factory to decode address

Dxxxxh on CS2.

Figure 5. External Data Bus Header, J7

One application of this connector is to connect a higher-resolution graphic
display. The J7 header pin-out is same as CrystalFontz displays. For
example, you can connect a CrystalFontz 320 x 240 graphic LCD display
using just a ribbon cable. You can also power the display inverter for back
light control using the 5 V supply on this connector. The eZ80Acclaim!

software example includes routines that can be used to drive a
CrystalFontz display.

LCD Interface

Figure 6 displays the LCD interface on the MDS-GP board. It provides

the following two different interface options:

•

Four-bit parallel interface (using GPIO pins), controlled by LCD
enable, LCD RD/WR, and LCD register select signals.

•

I2C/I2C bus expander interface enabled by jumper J26
(see I

LCD contrast can be adjusted using potentiometer R26. Software control
of the back light can be enabled using jumper J28. The default configura­tion drives the LCD in a four-bit mode using GPIO port pins of your MDS
processor module. For information on pins used, see Appendix—MDS-

All ROW pins are configured as inputs, All COL pins are configured
as outputs and are initialized High.

In a interrupt routine, one COL pin is set Low and the ROW pins are
polled to check for a Low state.

If any ROW pin is polled Low, the key scan interrupt routine returns
the key pushed.

On each interrupt, a new COL pin is set Low. Three interrupts are
required to perform a full scan.

GPS and Wireless Data Options

The MDS-GP board supports plug-in options for adding wireless data and
GPS functions.

A two-way wireless module can be plugged into connectors J17 and J19
on the back of the MDS-GP board. The connector pinouts support the
maxstream 900 MHz and 2.4 GHz radio modules. For module details and
ordering information, visit www.maxstream.net

A trimble lassen SQ GPS module can be plugged into connector J15. For
module details and sales locations, visit www.trimble.com

The MDS-GP board is equipped with two holes for adding a wire-tie to
secure the module to the board. Figure 8 displays a maxstream wireless
module installed on the underside of the MDS-GP board.

User Manual

Only two different serial port options can be active at a time. The MDS­GP board provides two ways to set active serial port options
(see Figure 9):

•

Jumper select options on J2 (seeTabl e 2 on page 20).

•

Use the I2C bus expander U2 to select options through software.
These options allow serial ports to be dynamically changed. You must
remove all J2 jumpers for software
selection to work.

Relay/High Drive Outputs

Figure 10 displays the two relays and six high-drive outputs included on

the MDS-GP board. By default, jumper J27 is set to route the 9 V to 12 V
DC power input to both the relays and the high-drive outputs. If 5 V DC is
used to power the MDS-GP board, then connect Pin 2 and Pin 3 on
jumper J27 to apply 5 V DC on the high-drive outputs.

The two relays installed on the board are 12 V DC types. These relays are
only supported when the 9 V to 12 V DC power supply input is used (see

Figure 10).

Troubleshooting

Overview

Perform the following steps before contacting Zilog® customer support to
submit a problem report:

1. Remove the MDS-GP board from the system; then, using your

processor module’s documentation, verify that your development sys­tem works correctly with the
MDS-GP board removed.

2. Use the instructions provided in the MDS General-Purpose Board

Quick Start Guide (QS0045) to reconnect the MDS-GP board and
return its jumpers to their factory default settings.

User Manual

23

3. Ensure that only one power supply is used which must be connected

to the MDS-GP board, not the processor module. Verify the power
supply input voltage with the system running.

4. Run the MDS-GP board example project appropriate for your

processor module.

If a hardware failure is suspected, contact a local Zilog representative for
assistance.
