ok finally plz plz plz someone reply seriously.............................after many days of sheer hardwork i have come to know everything abt 8051 and its softwares .........the only thing i m very unclear abt is the programmer..........i know which softwares to use to write the program and also which software to use to put that program in the 8051.............the only thing i m unclear abt is what hardware is needed to put that program into the microcontroller.......i mean what type to cable (i read something abt rs232 cables and max 232 driver) is used.......which pins are to be connected where........( pins of IC and the programmer).....what a programmer looks like.......tell me everything and assume that i am a complete novice in this field.....cause as far as programmers are concerned.....i m a novice......plz reply
there are two versions of circuit that i have...one is AT89C2051 and the other is AT89S51..................and i dont know if people are not able to gt me or what............i jus want to know that what all hardware do i need..
1) do i need jus a connector wire where in i connect the wire to my PC and the other end to a few pin of 8051 ( if yes then tell me the pins of 8051 which are to be connected to the wire)
or
2) do i need another circuit ( i guess its called a programmer....though i may be wrong) where in i connect the pins of my 8051 to this circuit and there is another wire that i needed to connect that circuit with my PC......
3) or do i need a circuit/programmer where in i put jus my 8051 and feed the program into it and then i when the program is done i remove my 8051 from that circuit and put it into my circuit
read this link and tell me wher are the 6 pins of header 6 are to be connected
It's a bit more complicated, I use a special programmer for 8051 which does nearly all variants. If you go the the Atmel site and download the PDF for AT89C2051 on page 8 there is all the timings for the programming. Atmel also include a circuit for a programmer.
