The port C0 is input. It should be tied high for the b0 to blink.hi,
Ran the hex file, the PORTB.0 pin only goes high once for a VERY short time and the program gets locked into repeating delay loop.
I am not able to write out a single bit.
Tried that. No success. In EPP mode, it took quite long (about 5 seconds) to attempt to program, but as usual the verification failed. In other modes it takes fraction of a second.Hi,
One thing to check, your Parallel Port Bios settings - worth trying all three types - just checked mine - its the default value of ECP+EPP.
It would be my honor I think. Lol.We should point future posters to this thread.
Mike.
But, I thought, Electronics wouldn't, Work/Don't Work by throwing a Dice inside them. There must be some theory or reasons, why it works/don't work. I thought, by the help of forum members, I would be able to spot the reason. No, hard feeling even if I don't succeed, But I will try, until I get bored.
Oh! sounds great. If the Price for such a simple programming interface is "Loose a single I/O pin", I am happy for that. I initially thought LVP would involve more complexities than HVP, so never ever thought in that side. The Datasheet of 16f877A says, LVP bit is factory set. Sounds Great. Are there more downsides to LVP?Perhaps you should try building a **broken link removed**. It is just a cable with 4 resistors.
You loose 1 IO pin and I am not sure how many chips are LVP enabled. A small price to pay by comparison.

But the program is non-issue here. I am not able to write out a single bit.
Never mind. sorry. That was not the intention. Are you really serious or kidding? Lol.Why has my offer to run your hex file, which you posted for me to try, earned me a 'mad' smiley.????

I messed up with the smilies. Real apologies.
Nope. I live in my stated location, Nepal.No problemo!
I just get the impression that you are feeling negative towards the posters trying to help you...
Do you live in the UK,???? I see that the stated location is Nepal.??
Nope. I have never build one. MPLAB does not have a driver for it so that is a deal breaker for me.Oh! sounds great.

But what software do I use? The IC-prog supports only com port? Do you know of parallel port LVP programmer?
Found it. And Going to make the LVP cable. Best of luck to myself.Nope. I have never build one. MPLAB does not have a driver for it so that is a deal breaker for me.
I think if you look at the parallel I would just find a computer with a serial port.

BTW, how to I tell ICprog that I am using LVP cable?
For programming, you can use ICProg from Bonny Gijzen. Configure as JDM-type-programmer (by reducing the setting of I/O-Delay you can speed up programming but increase the risk of errors).
I think I can safely Declare Now that: The parallel port PIC programmer and Software I tried Parallel Port PIC Programmer, don't work, and expert members here, can't make any more suggestions for making it work. So, Project Dead.
