Assalam o alaikum,

I am having some problems with PIC 16f877a i.e., it is working fine when i place it on my particular circuit showing good voltages but when i place it on my burner ckt and connect it to pc via parallel port, PIC Programmer doesn't verify the PIC and give error that "No PIC found".
I want to know that what could be the problem with my PIC as i have tried the burner with two my PIC's but it won't work, furthermore my friend PIC works on the same burner.
Try to give solutions so my PIC can work or else i have to buy new PIC :s

 

so many views and no reply?

 

Try your PICs in your friends burner. You have not got much help due to lack of information. It would help to know more about your burner software and burner design

 

bro, i have tried my PIC in my friend burner and that also doesn;t work, i am using pic programmer software

 

Do you have the schematics for your programmer?
