regarding heartbeat monitor - Electronic Circuits Projects Diagrams Free

warrior21 · 21st April 2006, 08:39 PM

hi
i am final year student and i am making my final year project as heartbeat monitor by keith wilson.
Can someone post the correct working hex code of this project.
Please help me regarding hex code because as i tried to build the hemon.asm file it contains many errors. As i am new to PIC programming so i couldnt resolve these errors.

The binary files are built for a specific microcontroller. The exact model would be required for someone to build it for you. You really need to be able to compile the source yourself.

I am attaching source code for the heartbeat monitor by keith wilson in this post.
This circuit uses PIC16F84 microcontroller.

when I am build the code .
then I get errors
these errors:
Message[302] D:\HEARTBEAT MONITOR SOURCE CODE\HEMON.ASM 79 : Register in operand not in bank 0. Ensure that bank bits are correct.
Message[302] D:\HEARTBEAT MONITOR SOURCE CODE\HEMON.ASM 81 : Register in operand not in bank 0. Ensure that bank bits are correct.

that are not errors , but just warning messages to make sure u havn't missed the bank select code.

pls i need quick help, i just constructed heartbeat monitor by keith Wilson and my circuit is not working at all. I programmed the PIC using the same source code that was supplied. Do i need 2 make modifications to my circuit? what type of waveform is expected at the LM358 output? I have a sawtooth waveform can this be counted by the pic? what modifications shld i make to the program?pls someone help urgently.

I had to say it, I just couldn't help it!

There's plenty of good stuff on this forum, but it's really annoying having to wade through so many 'begging' threads to get to it

im having a stab in the dark, but,

you may need to step up the voltage from the 358 so that it reaches the scale of 0-5V, and maybe use a schottky diode(are they the ones that limit hysteresis errors?) would clean it up abit.

im not sure if the schottky diode is the correct one, but whatever is the one im thinking of allows even sine waves to be counted accuratly by a pic..

ebonymj37 · 17th November 2006, 01:25 PM

Airight, thanks no begging, but there has been no reply yet and i have got limited time cuz it is for my final year project.

I suggest yoiu try fault finding then, presumably no one here has built the project, and the original authors site has disappeared.

The details can still be found Here.

Bloody hell is this for real?. A final year project is supposed to demonstrate your competance and skill as an engineer. If you copy someone elses project what does that show you have learned?

I dont know where your from but if your refering to a degree program final year project i would be totally ashamed of myself for ripping an entire project off and passing it off as your own.
