Dear All, I am new in micro controller programming, I have micro controller 89C51 and I need the circuit components and schmatic of the programmer ciruit which is interfaced to the computer with the serial port. Please some can send it to me Thanks Regards Sameh

why bother. why not use an ISP chip. More beginners get frustrated when building a programmer and then for the first go not knowing if it is the programmer or their code than anything else. Drop the build a programmer ideA and get a hold of some P89c51rX2 CHIPS. eRIK
To Sameh I am also new in programming but,I will send you overview of' pc based 89c51 serial programmer ' as soon as possible. please give me your email-id.
Oh, the kitchen table activity still goes on. More and more manufacturers (I know of Philips and Atmel) are removing parallel programming info from their data sheets because of all the grief they get from those that insist on making programmers on their kitchen table. The official policy is "we will privide parallel programming info to certified programmer manufacturers". Why, oh why does this activity still go on when there is a plethora of ISP chips available? Erik
"Why, oh why does this activity still go on when there is a plethora of ISP chips available?" Absolutely! Some require nothing more than a serial cable and Hypoterminal: http://www.8052.com/forum/read.phtml?id=98557 http://www.8052.com/forum/read.phtml?id=98921 http://www.8052.com/forum/read.phtml?id=98909
Hi i need 8051 programmer circuit scheme, you said you have it. can you send me please? thanks a lot.
i need 8051 programmer circuit scheme, there is no such thing a Philips chip program very differntly from an Atmel chip which program very different from a siemes chip which program different from .... why do you not just use an ISP chip such as the P89V51RD2 or the SILabs offerings. It save you more in aspirin than the cost of the chip. You will, with a kitchen table programmer, be much more likely to fight problems in the programming (which teach you nothing) as opposed to actually debugging your code. Erik
i need 8051 programmer circuit scheme, [Erik]there is no such thing Well, there is a thing that can meaningfully be called an "8051 programmer" --- but it's not something anybody should expect to get a "circuit scheme" of, what with it being a rather chaotic mess of several dozen kilograms of various hardware (with a surprisingly high content of water), sometimes misleadingly referred to as a "person" or "homo sapiens sapiens". ;->
"sometimes misleadingly referred to as a 'person' or 'homo sapiens sapiens'." Better avoid any references to making one of them on the kitchen table...! ;-)
need 8051 programmer circuit scheme, [Erik]there is no such thing I did refer to the circuit, not to what Andy refer to, although that does sound like fun :) Erik
pleas send me about microcontroller 89C51
"pleas send me about microcontroller 89C51" Send you what - price? colour? weight? what???
hello send for me PCB or circiut of programer thanks
send for me PCB or circiut of programer any particular reason you did not read the whole thread? Erik
please send me circuit to designn the 80951 programmer.
