1 Overview

1.1 System Development Kit content

Thank you for purchasing our product. If you take care on the different
hints in this manual you will have great success in software development
with this microcontroller. Please refer to the documents listed in appendix.

The System Development Kit
contains the following parts:

Evaluation-Board HTEB1
CD-ROM
User manual (this document)
RS232 cable (1.8m, DSub9, male­female)

4 plastic feet for the HTEB1

Carefully remove the board from the shipping carton. Check first if there
are any damages before power on the evaluation board.

1.2 Hardware description

The Hitachi-Tiny-Eval-Board (HTEB1) is a low cost multifunctional
evaluation board for the Hitachi Tiny H8/3664F microcontroller. It can be
used stand alone for software development and testing or as a simple
target board. You can use the Flash-Download-Tool (FDT) for
programming the target code or work with a debug system (E10T) at the
provided connector. The board allows the designer immediately to start
with the software development before his own final target system is
available.

This eval-kit provides some additional hardware e.g. 8 LED’s, a 2*16
Character LCD, 4 key’s, a PC-AT-keyboard connector, an I2C-connector
and more for hard- and software evaluation. All peripherals are used by
some software application notes. Please refer chapter 3.

1.5 Jumpers and switches

JP1 is used for switching the serial interface from 1:1
to crossed connection. If you connect a 1:1 cable (like
the cable that comes with the kit) use the default
setting. If you connect a crossed cable set the jumper
to alternate setting.

JP3 is used for the LCD-LED backlight. If the jumper is
closed (1-2) the backlight will be ON. Remove the
jumper (=open) if backlight operation is not
necessary.

JP2 is used for I2C interface

JP4 is used as an output for the DAC or for PWM

S_PROG/RUN switches between RUN- and
PROG(PROGRAMMING) mode.

KEY_1 (T1) to KEY_4 (T4) are user keys.

RESET_KEY (T7) is for reset.

Main crystal (Q1) can be changed to another
frequency. Therefore a crystal socket is provided.
Please refer to the microcontroller hardware
documentation for recommended devices. The crystal
type should be a HC49 / HC49U type. Eventually
change the capacitors C6/C7 if necessary. If you
change the crystal frequency take care on possible
changes by flash download tool (see FDT manual).

1.7 Start-Up instructions

1.7.1 Installing the HTEB1

Installing the HTEB1 requires a power supply and a serial connection to a
host computer (common PC). The serial communications cable for
connecting the HTEB1 to a host computer is supplied and has 1:1
connectivity.

PC with COM1/2

Power supply
7,5-9V DC

Figure 1.8 shows how to connect the HTEB1 to a PC and to a power supply

1.7.2 Power Supply

The HTEB1 hardware requires a power supply of 7,5V DC at minimum.
Please don’t use a power supply with more the 9V DC because the on
board voltage regulator becomes very hot!

The HTEB1 power consumption is about 180mA with LCD-backlight ON.
Since total power consumption can vary widely due to external
connectors, H8/3664F port state, use a power supply capable of providing
at least 300mA at +7,5V DC.

The design includes circuitry for reversed polarity protection.

Please watch on GND (ground) connection between power supply, eval­board and PC.

1.7.3 Test program

The HTEB1 is supplied with a short demo application when delivered. If
you power up the eval-board for the first time, you will see a start up
message and some LEDs lighting.

If no message appear, please set the switch “Prog/Run” to “Run-Mode”
(right position) and power up the board or, if already done, press the
reset-button.

The demo application contains a small “Running-Light” application. The
keys can be used for control the state, P2 is used as speed control. First
press the key T3 (RUN) for starting demo application. Then you can check
the functionality by pressing the keys KEY T1 to KEY T4 or change the
value of potentiometer P2.

[…]

Figure of the Demo application. “Running Light”

Any time you want to reset the application press the reset-button. If you
want to reload the demo application later (after reprogrammed the eval­board) you can find the code on CD-R in the directory
“X:\examples\flashdemo\runlight.a37” (For X use the appropriate char
from your CD-ROM).

1.7.4 Software Installation

Software development on embesso-HTEB1 requires some software tools to
be installed on your PC. All tools can be found on CD-R. Some of them
must be installed separately. Please refer on installation / setup
requirements.

You will find the following tools:

EWH8: IAR Embedded Workbench with a limited version of the IAR

C compiler for all Hitachi Tiny controllers, assembler, linker
and library generator

FDT: A powerful freeware flash tool (flash-writer) from HMSE

Installation hints:

EWH8: Install EWH8 by start \programs\iar\autorun.exe . Follow

the instructions in setup and look at the readme.txt file.

FDT: Next install \programs\fdt\ftd15.exe. Then the plugin

fdt3664f.exe must be installed. Follow the setup
instructions. A documentation will be found in fdt_man.pdf.

If you have installed these tools please refer to the next lessons for
workflow.

NOTE: Most freeware tools are unsupported versions! Please refer
to manuals or hints on website for FAQ’s!

It is strongly recommended to refer all additional documents like
H8/3664F hardware manual and H8 programming manual. Please see the
application notes and several readme files on CD-R. Sometimes you
should watch on the Hitachi, HMSE and IAR websites for tool upgrading,
news and latest versions of all tools.
