HTEB1 User manual 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.
HTEB1 User manual 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. Orientation LEFT RIGHT Operation PROG(programming) mode RUN mode 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.

HTEB1 User 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.
HTEB1 User manual 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.
HTEB1 User manual 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.
HTEB1 User manual 2 Development Environment 2.1 Creating a program using IAR-EWH8 Software development can be done with a integrated embedded workbench like IAR-EWH8. This software contains an editor, some tools for organization and a tool chain for compiling, assembling and linking programs. Start IAR Embedded Workbench on your PC. The following window will appear: Now select File / New and select “Project” Issue 0.
HTEB1 User manual Press OK and a file window will appear. Here first create a new directory (e.g. c:\MyTinyTest) and type the project filename “MyTinyTest”. After that click CREATE. Now a new project is created and we must do some settings. In the window select under targets: “RELEASE”. Issue 0.
HTEB1 User manual Now select release with the right mouse button. A popup appears. Select Options… and do the following settings: In selection ICCH8/List select the List file box. In section XLINK/Output select under Format “motorola” as the output format. Issue 0.
HTEB1 User manual On the CD-R you will find a file called “hteb1.xcl”. That file must be used as the xlink input file. Please copy it to your target directory and select in section Input/XCL file name the file hteb1.xcl. Issue 0.
HTEB1 User manual All other options can be changed later. Click on OK. Now select File/new/source file and type in the following program: /* MyTinyTest */ #include "ioh83664.h" void main(void) { unsigned int x=0; unsigned char c=0; PCR8 = 0xff; PDR8 = c; while (1) { while (--x); c++; PDR8 = c; } } Issue 0.2 /* /* /* /* counter */ holds port output */ port is output */ all LED's on (inverse) */ /* wait ...
HTEB1 User manual After that save it under MyTinyTest.c Now we must add this file to our project. Please select Project/Files and add the file MyTinyTest.c. Issue 0.
HTEB1 User manual After that click on DONE. Now you can select Projet/Build ALL (or F9) and all files are compiled and linked. The message window shows if your project is error free or if there are any errors. Issue 0.
HTEB1 User manual The target file for download can be found in directory c:\mytinytest\release\exe\mytinytest.a37. Please see chapter “FDT” for information about downloading this file to target system. Issue 0.
HTEB1 User manual 2.2 Download the code using FDT After compiling and linking (error free!), the target code (mytinytest.mot) should be downloaded to target board. Therefore we use a freeware tool from HMSE : FDT. Even FDT must be prepared for a new workspace. Issue 0.
HTEB1 User manual Please start FDT and select „New Workspace“. Here we use the project name “MyTinyTest”. You can choose a location for all workspace files. Select on subdirectory from „MyTinyTest“. Click ok and a further window will appear: Select „Yes“ Issue 0.
HTEB1 User manual First time users should use the wizard! Fill in the following things: Issue 0.

HTEB1 User manual Now a workspace is created and you can add your target file to „TargetFiles“: Select Project/Add new files to project… and search for file: c:\hew2\mytinytest\mytinytest\release\mytinytest.mot. Issue 0.
HTEB1 User manual Now make a double click on \targetfiles\mytinytest and the file content of mytinytest.mot will appear in hex format in the right window. First press the reset button at the target board, hold it down and move Prog/Run-switch to prog position (left). After that release the reset button. With Image/Download image (Ctrl-P) you one can start the connection setup to target board and start downloading image file. Now press Ctrl-P (Download) on FDT and the download process will start.
HTEB1 User manual Now you can do some additional functions in HEW. After compiling and linking only go to FDT, update your download file with the command Freshen all Target files (Ctrl-T), reconnect the link and repeat the download process. Issue 0.
HTEB1 User manual 2.3 Workflow Issue 0.
HTEB1 User manual 3 Examples HTEB1 is provided with some demonstration code. 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.
HTEB1 User manual 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.

HTEB1 User manual 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.

HTEB1 User manual 3.3 SCI SCI is used here for a simple RS232 (V24) terminal connection. Please use a terminal program like HyperTerm (included in Windows), select Baudrate 9600 Baud, 8 Databits, No Parity and 1 Stopbit (8N1). After connection and setup, hit some keys and you will see a message responding on every keycode sent. /* **----------------------------------------------------------------------** ** main.
