request to convert ASM file to HEX file for PIC based CDN timer

[manoj madhavan]

Help me please.............

I have a timer circuit diagram and an *.asm file. I try to convert to *.hex, but not succes.


I attached the schematic and *.asm file herewith.

Can this circuit convert to this type.... ( Canverted Timer 2)

can help me anyone please?


Thanks in advance

Hi,

The chip shown the 16C84 is a one time only programmable chip and it is effectivley obselete.

It might be possible to make the code run on the 16F84A chip if you can get that ?

Also the diagram and code make no mention of what frequency the crystal should be - it is a critical component.

Hi,

Have slightly modified that code to work on a 16F84A and it seems to simulate ok based on a 4mhz crystal, though cannot be sure thats the right value for real time.
The revised Assembler code is below which Builds fine with MPlab, but ensure you have the Disable Case Sensistivity box Ticked, its in MPlabs Project, Build Options,Darkroom.asm

There are lots of more up to date 4 digit darkroom / countdown timers on the web , this Piclist site is usually good http://www.piclist.com/techref/microchip/cntdn/index.htm

Hi wp100

Thaank you for your attenssion on my post.

I get you, what you mean. But i want the hex file too.

Can you make hex file from the asm ? and send it to me?

Thanks....

Hello..

I want to construct a 3 digit counter, which count 5.00 minutes to 0.01 seconds.

Only want 3 digit display.....

I will be explain for what i want to make, if you like to hear..

Thank you again

Hi,

Yes, it would be interesting to know..

The hex file created from the Assember file I sent is below.

Hi,

Thank you very much for your work. I want to simulate the circuit with your hex file later. Now I want to say thanks again.

I need a timer with 3 digit 7 segment display.

my suggession is as follows you can choose any microcontroller)

1. 3 digit, 7 segment display

2. Each digit can need UP/DOWN setting switch

3. It must can set time 9.99 minutes to 0.01 seconds.

4. When we set 5.00 minutes in display, it mean the "ON" time of the Timer System.

5. Then press the "SET" switch...the timer will run countdown...and output will be "ON" for 5.00 Minute

6. When the time reach the target or 0.00, the output will OFF and again rollback the display in 5.00

7. Then we dont need to start the timer for five minute ( 5.00 ) again, just press the "SET".

Its my poor language...sorry for that....But i want to understand you, what i think.

I think you can get my idea and what i need....may i hope your valuable help again?


Thank you so much for your Help.
Thank you so much for your Help.

hi all ...........

I have timer circuit.....I need to include START/STOP, SET switch the circuit if anyone can....I think it is the best......but no switch in working condition...

thanks in advance

Hi,

This forum is to give people the advice and information to complete their projects, don't think you will find anyone willing to re write someone elses code for you.

In a quick Google I soon found some darkroom timers with the features you are looking for - this page shows a very detailed project that gives me confidence it will work.

hi wp100

Thanks for your comments....and I check the above link. Interesting, but i want only 3 digit display....so what can i do? any other link? please....

Thanks wp100 for your valuable help....thanks again and i hope you can help me more...

Hi,

Why is 4 digits such a problem ? usually a timer has 2, 4, or 6 digits to count full seconds or minutes or hours.

 

[manoj madhavan]

hi wp100

I only want to count 9.99 minutes to 0.00 seconds....when incresing one digit, the programe will much complicated, I think....

Any suggessions?

Hi,

Those previous example do not work very well and are poorly documented.

Unless you can find a good example on the web the only other choice is to write your own.

If you want to use Pic assembler then this is a good starting point.http://www.winpicprog.co.uk/pic_tutorial10.htm
There is a 3 digit tutorial here

You could look for other examples in C or even a different micros like the Arduino

how to convert to text to asm file?

and i want to display "Hotel Kadambari" insted of the above message :"TEL:13973637434"......please help me..



Thank you

Hi,

What you have there is Assembler.

Its a block of data, typically used to send to a liquid crystal display

From Mplab Help on 'DB'

db - Declare Data of One Byte
Syntax
[label] db expr[,expr,...,expr]
Description
db - Data Byte.


Simple Examples
Example1: PIC16 Devices

db 0x0f, "t", 0x0f, "e", 0x0f, "s", 0x0f, "t", "\n"
ASCII: 0x0F74 0x0F65 0x0F73 0x0F74 0x0a00

Have you found a suitable timer program yet or are you trying to write your own ..?

 

[manoj madhavan]

Hi sir......i am tired..not yet get suitable timer program !!!!

Now i am trying to build a moving message display. can you check this and help me to build.......

 

[wp100]

Hi,

Those files simulate ok, but they are quiet big and expensive circuits, and the code shown has little to explain to you how its working.

Also they are using the ATmel chips and ATmel Assembler which as not the same as Microchip Pics.

Why not start with something simpler that you can readily understand and then build on that.

This tutiorial covers both the software and the cheap and simple hardware.
http://www.winpicprog.co.uk/pic_tutorial13.htm
http://www.winpicprog.co.uk/pic_tutorial_matrix_led_board.htm


The trouble with using other folks code is you learn very little

It you really want to get into Assembler programming then all those lessons are a good place to start, just coding your own single Flashing LED is a real sense of achievement

 

[manoj madhavan]

hi, thanks for your valuable suggesstion.....

I will be back with good result in PIC or any other microcontroller.......and thanks for your links too.....its quite good for me...

Thank you

 

[manoj madhavan]

hi wp100

finally i get a timer design with all files.........but i want to some changes in the asm file. but I am not know how to edit the asm file which i want.

can you help me....check the attachment please......also has proteus simulation and what change i need, its has a PDF file too......so please help me....its very urgent.....that I contact you really

Thanking you

manoj soorya

Hi,

Yes ,it seems to run well in Proteus, but afraid I do not know the ATmel chips or C programming so cannot help you modify things.

Hopefullysomeone else might come and help you...
