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)
