Hi , i want to use the PIC and interface it using rs-232 cable and display it on visual basic.
I m attaching my code in the notepad. please can some one help .

I've had a quick look at your code and you have written a lot of code. You seem to have a good grasp of general programming but there are some obvious errors in your code. You don't save or restore the context in your ISR and you don't have a retfie at the end of it. My suggestion is that you try to get simple programs working first and work up to something as complex as you posted.

I am using this code for real time display in the computer through visual basic and rs-232 cable. I have successfully created hex file and build was succesful too. If you could help in writing it , please bcuz i have put a lot of effort , i would be grateful if someone could help me fix it. pleaseeeee.
WHY have you started a new thread while Im still answering your first one.Originally Posted by olympus123456

its because i got nervous after all this of writing the program sweating and crying and all this , i find out that something is missing . i felt broken . i really need to finish this by may end . i m sorry dude.
I'm sweating and crying trying to help you sort out the program, dont be so impatient, Im not on the clock.

sorry eric. i m soo sorry , i know i bcame impatient bcuz of 3 months of work on this code dude. really thank you soo much . lastly, shuld i just the code that u wrote in the top or end. how does it work . if u dont mind could u tell me .
Can you post a schematic of your device. Have you built it yet?
PS your PK2 can debug the 16F877 this may help with working the bugs out.
I have not yet completed it . i need some more time , because i have to find photoelectric sensors , ecg electrodes . I am attaching the schematic of the circuit , its not in eletronic workbench its drawn by hand.

You've only got a week to finish the schematic (post it as we can help spot errors like missing bypass caps etc) get parts, program, built and test it. Good luck.
i have posted it .

That's the program not the schematic.
PS if you don't comment your code it's very difficult to follow.
Its ok blueroom , i got to hex file and ERIC helped me in enabling the pins. I m posting the schematic. I hope programming the PIC is solved , still i have to send it to the PIC . i bought pickit 2 , but i dont know how to proceed, how to send the hex file to the PIC. if you can help me on that.
Also about visual basic, do u have any knowledge of it ?
Well you will need 0.1uF decoupling caps near the VDD, VSS pins. 16V caps will work with the MAX232.
You have to connect the PK2 to VPP, VDD, VSS, PGC & PGD it will also debug if you leave it connected.

I will continue working on it tomorrow sort of exhausted and damn tired , thank blueroom and others. be back tomorrow.
