Hard disck and DS1620 EQUIRY

I keep receiving error messages which mite be related to my hard drive fail. How can I solve this.

I am also trying to run the DS1620 chip. I am not sure where to connect the high thermostat , low thermostat and combined thermostat, it is not clear on the schematics. Pin 4, pin 5, pin 6 is linked to the datapin, clock pin and enable pin.

Cheers.

If your harddisk is failing, run some tests, search for bad sectors etc.
If you get too many errors, get another harddisk.

Thigh, Tlow and Tcom are outputs. If you don't need them, leave them unconnected.
Read the ds1620 datasheet. That info is on its first page.

I have left them Unconnected and downloaded the program. What should be the download response? I see no javelin reply.

Cheers.

I assume you use the ShiftDS1620.java program.
Here is the mainloop of that program:

· public static void main(){
··· dsInit(setup);
··· while (true){
····· System.out.print(HOME);
····· System.out.println ("Celsius temperature: ");
····· System.out.println(dsTemp(READ_TEMP)/2);············· // Divide by 2 for deg-C
····· CPU.delay(5000);
··· }··············································· // end while
· }················································· // end main

What do you think the output should look like ?

This is my code, do you recommend me to change the main loop at the bottom. As mentioned I have not connected the High therm, low therm and combine therm.
I have downloaded the program to the stamp successfully but I don`t receive any reply. Cheers.

// Program Listing 9.4 - Using shiftOut on 75xx595 shift register

import stamp.core.*;

public class Shift74595 {

final static char HOME = 0x01;
final static int DATA_PIN = CPU.pin0;
final static int CLOCK_PIN = CPU.pin1;
final static int PULSE_595 = CPU.pin2;

static void write595(int number){
CPU.shiftOut(DATA_PIN, CLOCK_PIN, 8, CPU.SHIFT_MSB, number <<8 );
CPU.pulseOut(5,PULSE_595);
} // end write595

public static void main() {

CPU.writePin(PULSE_595,false);
CPU.writePin(CLOCK_PIN,false);

while(true){

for (int i = 0; i <= 255; i++){
write595(i);
CPU.delay(2500);
} // end for
} // end while
} // end main
} // end class

This code is not for the DS1620 that you mention in
your post.
To test the DS1620 you need Listing 4.7
(program ShiftDS1620.java)

Using the program Shift74595 with the DS1620 is pointless.
