i need AT89C51 programmer circuit.If any one know it please send me.Thank you...
If you want to program your AT89C51 - don't you think it is better if you buy a working solution instead of hoping for people to have schematics to something that maybe works?
If you use a home-made programmer and something doesn't work - how will you know if it is your home-made programmer, or your prototype that doesn't work?
When you do select a processor to use - always keep the "how to program" question very high up on your requirements specification. Never select a processor unless you know that you can get all required tools (compiler, debugger, programmer, ...) to an acceptable cost and that the tools are actively maintained.
I can not count the threads that I have seen here and in other fora "I have made this guranteed working programmer from somewhere on the web and I can not get it to work"
Do yourself a favor, get a chip with either UART or JTAG ISP. (NXP Atmel ...Rx2, SILabs more)

Hi,
this is the very easy projekt to make.
see it www.woe.onlinehome.de/e_projects.htm
it helps you i hope
yes yes
again i do not onley say Please read the manual as others
Master Zeusti
"again i do not onley say Please read the manual as others"
But are you saying that AT89C51 is identical to AT89C2051?
Are you giving your personal recommendation of this programmer after having used it extensively?
again, we miss the __master type qualifier. what is happening here.
just waiting for the post "I made it (no mentioning of "with flying leads') and it does not work as promised.
as usual we see the blind leading the deaf
PS no one said Please read the manual, but there was solid advise "more have failed than have succeeded"
No body tryed to say where but me!
Some body asks 'where can i buy the bread?'
One asks 'why you want bread?'
One say 'cake is better'
One say 'there is lots of other things'
One say 'you can buy it but it is not what you want'
Just me say 'you can get it at the shop'
"Just me say 'you can get it at the shop'"
No, you say: I found this bag of white powder behind the local factory. I don't know what it contains, but try to use it as flour when baking your bread.
I ask you once more: Are you sure that a programmer for an AT89C2051 is also the correct tool for an AT89C51? Have you tried it?
You seem to be giving out advice without knowing if the advice is good or bad. Do you recommend this programmer based on own personal experience with it?

And you tell him where to buy bread without telling him it might be poisonous.
Since I am totally impressed with your postings I do not see the need to state that the anlogy is "posionus bread" to "circuit you can not make work"
Actually, it was Per who recommended that he should get it at a shop.
You just posted a recipe for a different kind of bread.
We have no idea whether the OP has the necessary skill & equipment to follow the recipe correctly or, even if he does, if the result will be suitable for him...
If the OP eats it and gets sick, we won't know if it's just because he's a bad cook, or if it's a bad recipe. Or both.

or maybe it was the powder thing mentioned above ;-)
A similar request to this one was answered in:
http://www.keil.com/forum/docs/thread3459.asp
I decided to mothball the project because it became clear that the market just wasn't ready for it at that time.
If anyone is still interested, please just contact me directly and I'll look into resurrecting it.
I s'pose your first step would have to be a Vista version?
Maybe you could also integrate a bread maker...
Vista version? A general-purpose programmer don't need special versions for Linux, FreeBSD, Vista, Solaris, ...
Easy - No worries about Vista support.
I'll just add a few ifdefs.
Who said multi-platform, portable code was a myth?
The projects's already full of them for Linux, FreeBSD, Solaris, WFW, CPM, BBC, SPECTRUM, LOW_ENDIAN, HI_ENDIAN, 8051, Z80, 6502, ARM, TI89 etc, etc, etc.
Actually, at the moment, there's considerably more lines in the source file to control the conditional compilation than there is actual code!
Wot, no VMS?!
