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, male-  
female)  
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

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, eval-  
board and PC.

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 eval-  
board) 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).

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:  
FDT:  
IAR Embedded Workbench with a limited version of the IAR  
C compiler for all Hitachi Tiny controllers, assembler, linker  
and library generator  
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.

On the supplied CD-R you should find a complete prepared workspace for  
IAR-EWH8.  
\examples\demoapp\demoapp.prj  
Please copy the complete directory to your hard disk in a directory  
c:\H8TinyIAR, so you will finally have the following directory (per  
example) “c:\H8TinyIAR\examples\demoapp\” with all application notes  
included.  
Then start IAR-Ewh8 and select “open existing workspace”. Select one of  
the projects and do your exercises.  
For all projects we need the same header file containing some definitions  
and the include file for the target microcontroller H8/3664F. So if you  
want to work with these files don’t forget to include the file “mydefs.h”  
first in your project file:

3.1 Key’s and LED’s  
The first demo program shows the usage of LEDs and keys on HTEB1. For  
time-controlling we use TIMER_A as an periodic interval timer. The  
interrupt service routine (isr) is checking the state of the keys, actualising  
the LED port and reading out the AD1-channel to determine the running  
light speed. If you want to do some experiments, first check out to find if  
other LED pattern maybe in form of a table read out or calculate them by  
functions developed by yourself. If speed control should be changed, first  
change the calculation of the A/D-conversion value to timer ticks.  
/*------------------------------------------------------------------  
** KeysLEDs.c contains some sample code for using LEDs and Key's

3.2 LCD  
One of the highlights of the HTEB1 is the 2*16 character LCD with  
backlight. Simple functions are provided here to demonstrate the usage of  
the LCD. Please refer to the LCD manual for further information (e.g.  
commands, other character sets etc.).  
The demo source contains some definitions to reset and initialise the  
display. Then we make some simple write outs.
