please i need some help

[arsalanghouri]

dear all i have a really big asm code and the problem is it is not working is there any one who is really good at assembler codes who can check it ?? please reply

 

[ckshivaram]

Who has written the code. you or others. What is the purpose of the code. What do we understand by it is not working???? Does it have errors or logical problem???Tell the requirements and post it as attachment rather than copy pasting line by line.

 

[arsalanghouri]

ok i didnot write the code and other things are in side attached file
it is not working means the circuit is not working with this code programmed in ds5000t micro controller

 

[ckshivaram]

any other docs you have for this, like flow chart, algorithm, which will help us to give fast reply. Is it the circuit that you posted in other thread related to this project?

You have to accept that many projects posted on the web do not work for some reason - you have chosen a project with a dallas micro which is not seen in this forum very often so perhaps you might be better looking for something using the more common PIC or AVR micros .
You could try programming one yourself ..


Have you actually bought that Dallas chip or are you just simulating it ?

 

[syeda amna]

its true many of projects from web do not work because there might some errors in programming or schematics.

so have a look on programming.

A reasonable way would be to debug the hard- and software by checking it's operation step by step. If the original software doesn't provide test functions (I don't see any a first sight), then it should be modified respectively. You can start with simple things:
1. Make the LED blink unconditionally
2. Make the LED blink at key press
3. Output some test text to the character display
4. and so on

Obviously, suitable test steps depend on which test tools are available to you, e.g. a multimeter, an oscilloscope ...?

At least the assembly text style looks good, so as a first guess, I would rather suspect the hardware setup.

By the way, can you be sure to have transferred the Hex image correctly to chip?

Finally: You decided to do a 8051 assembler project. Then you should learn 8051 assembly language.

i have bought the dallas chip and tried making the circuit but it does not worksi am posting more info about the project below please help me
i dont under stand is this information enough for the working of the circuit or do i need some thing else
can i post here the link to site from which i saw this project?

should there be semicolons before the line as follows??? look at the bold lines please

; FILE NAME 4Bit5000.ASM
;
; Project: DALLAS DS5000T MICRO Clock/Callendar
; Programmable Event Timer
; 11.0592 MHz Crystal
; LCD = { 20 X 4 }
;
; 4 bit LCD Code
; With user input buttons.
;
;
; ========================================================================
; This project incorperates the Dallas DS5000T in a simple control system.
; In normal mode it simply displays the date and time, and allows setting
; of these functions with user input buttons. The buttons change function
; somewhat in the subroutines. In the normal mode Button #1 moves the
; the user to the Time setting routine. Button #2 moves the user to the
; Alarm and Control setting routine. Below is a diagram of button
; functions for each subroutine.
;
; Time Set Routine Setting Alarms
; Button #1 Go Back Go Back
; Button #2 Increase Daily Alarms
; Button #3 Decrease Control Alarm Status
; Button #4 Enter Control Alarm Set
;
;
; Daily Alarms Control alarm status Control Alarms
; Button #1 Go Back Go Back Go Back
; Button #2 Increase Go Forward Increase
; Button #3 Decrease Go Back Decrease
; Button #4 Enter Show Settings Enter
; [ Any button breaks out]
; [ of Show Settings ]
;
; In all setting routines the arrow indicates which number will be
; acted on by the buttons.

should there be semicolons before the line as follows

The said lines have been commented out, because the respective register symbols are unused in the code, as a text search reveals: No interrupts, no timer, no serial interface.

By the way, if any needed symbol is undefined, the assembler exits with an error.

I think ckshivaram has asked a good question in his first post, it has been answered yet.

can any one of you give me your gmail email id or facebook id where i can chat with you please this is my first project and i am a begginer please help me
