Note

I'm developing for this board, the wiki page will be improved soon

feel free to contact me (see the contact below)

Introduction

the board firmware runs a tini java virtual machine, which is pretty able to boot to board, to upload java application, and to run it

The Target-goal of this page is

• have appeal with it
• have experience with I/O driver written in java (do you really think it i impossibile ?)

People you could contact if you need help

• flameman, i'm currently use this board for a project, email
  • email flamemaniii@gmail.com
• you ... if you want ;-)

Overview

The board consists of:

• CPU max80c390 max80c390-user-man.pdf
• RAM onboard __KB
• UART 2xRS232
• POWER 5V
• System PCB xxx cm x xxx cm

Memory Locations

memory map of the board will be added as soon as possible

addr begin	addr end	area
...	??	ram, userspace

javac-390translate java to pseudo 51 assembly

• javac-8051 machine layer has been ported to 80c390, but there is no public assembler
• dalsemi has released a java version of java compiler and 51 assembler and linker

modern java environment are not compatible with java-51-assembler

so if you need this old java environment email me i will provide the java binary

draft

doing a project sing a "TINI Board" which is a 10 year old peice of gadgetry which hosts a web server, and using java applets, one can control the outputs (in this case LEDS) using java.

the following turns on a yellow LED, which i am taking the output to control a relay and do various things...

manip.add(LEDManip.Y1);
lcdmanip.clear();
lcdmanip.out.println("Current Move:");
lcdmanip.out.print("Elbow Down");
lcdmanip.out.flush();
pause(5000);

In the following code

---

import com.dalsemi.system.*;
import java.net.*;
import java.io.*;
import com.taylec.tini.*;
import com.taylec.tini.io.*;
import java.lang.*;
import java.util.*;
import com.dalsemi.system.TINIOS;
import java.util.Enumeration;

public class elbowdown
{
/**
* Pause
*/
private static final void pause(int delay_)
{
try
{
Thread.sleep(delay_);
}
catch (InterruptedException e_)
{
}
}

public static void testLED(Interrupt interrupt_)
{
try
{
LEDManip manip = new LEDManip();
LCDManipFormat lcdmanip = new LCDManipFormat();

//setup local variable to use for state manipulation of LEDs
int cur_state = 0;

//turn off the LEDs
manip.clear();

manip.add(LEDManip.Y1);
lcdmanip.clear();
lcdmanip.out.println("Current Move:");
lcdmanip.out.print("Elbow Down");
lcdmanip.out.flush();
pause(5000);



manip.subtract(LEDManip.Outer);
while(true)
{ manip.subtract(LEDManip.Inner);
if (interrupt_.getNumEvents()>0)
{
return;
}
}
}
catch (IllegalAddressException err_)
{
System.out.println(err_.toString());
}
}


public static void main(String args[])
{
Interrupt interrupt = new Interrupt();

System.out.println("Starting Motion");
testLED(interrupt);
System.out.println("Ending Motion");
System.exit(0);

}
}

When i run that code, the program continues to run and stuffs up the next one from running, so i need it to exit without having to use the interupt (a button on the TINI board) I thought it would be logical and just have the import part, then the function definition, then the LED control part, then the function stops, however when trying to remove bits, i keep getting errors.
