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
please send me circuit to designn the 80951 programmer. evidently you can't read "there is no such thing" you must be specific as to which derivative evidently you can't type there is no chip nemed 80951 that can be programmed with keil tools. Erik
thank u
please send me 89c51 programer circuit
there us NO SUCH THING!
somebody may have a circuit to program an AT89C51PQZ, somebody may have a circuit to program a I8051RST etc.
There is no programmer for 'generic' '51s. All manufactureres have their own programming algoritnms and, in many cases, the algorithm is not the same for different chips from the same manufacturer.
1) what does Keil have to do with 'circuit' 2) if you want to program a chip why not make it easy on yourself and use an ISP chip?
Erik
thanks for such a information

Keil: Think about a little update of this forum, so that specifically marked threads may not be scanned by spiders.
This seems to be a thread that too many picks up from google and ignores to read - not even checking the age of the other posts.
Or why not just lock this thread?
hi plz send ckt diagram
ckt diagram sent.
how do you know that the circuit you sent fit his uC?
it may be an I89C51, an AT89C51 or a P89C51 and they all program differently
eller er det her bare et forsoeg paa at faa ham til at holde mund?
I neither found a specification for what chip or schematic to send - or to which address - so I did the best I could:
I settled for sending a schematic to myself :)
(Jo - vissa frågor passerar gränsen. Ett Turing-test skulle snabbt utesluta en människa, och därmed förolämpa de flesta maskiner...)
i was thinking of starting off wid AT89S51..i read the data sheet and it talked abt programmin thro' MOSI, MISO and SCK pins(in serial mode ofcourse)... i have worked with MSC1210 before and used Keil...there wasnt much fuss involved there....i developed the code, downloaded the hex file thro' TI Downloader... can anybody throw some light on serial programming in case of AT89S51???
not cute, just difficult to read.

with about programming through
is that too difficult to type?
All right!!!! SO how do we go about programming AT89S51??
You said you had the datasheet - that tells you what to do!
What additional information do you require??
You can alos go to the Atmel site, and look at their information about doing it...
OK, just tell me one thing: can i use RXD0, TXD0, GND lines of AT89S51 to download hex file(through hyperterminal) as is the case with MSC1210?? Because in the datasheet they talk about using MOSI, MISO,SCK lines and also about some instructions for serial programming.
