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?

 RE: 89C51 programmer circuit

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?

 RE: 89C51 programmer circuit

please send me programmer of 89c51

programmer of 89c51
THERE IS NO SUCH THING

There may be a programmer for AT89c51, there may be a programmer for P89c51 there may be a programmer for I89c51, but the programmer for those 3 is different. However 'identical' derivatives may be, the programming algorithm is nearly always unique. Even different generations of chips from the same manufacturer often have different algorithms. As an example, the P89C51Rx2HB program different from the P89C51Rx2B and again different from the P89V51Rx2 .

 RE: 89C51 programmer circuit

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 :)

 RE: 89C51 programmer circuit

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???

All right!!!! SO how do we go about programming AT89S51??

 RE: not cute, not smart, just difficult to read.

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...

 RE: not cute, not smart, just difficult to read.

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.

 Do what the datasheet tells you!

"in the datasheet they talk about using MOSI, MISO,SCK lines"

If that's what the datasheet says, then that is what you must do!

Simple as that.

 RE: Do what the datasheet tells you!

http://www.atmel.com/dyn/resources/prod_documents/
C51_Hardware_Connections.pdf

This link shows hardware connections for programming through UART; but they havent shown connection scheme for programming through SPI

*****************************************************
Where as in the datasheet AT89S51 they have explained only SPI way of downloading!!!! ANd no mention of downloading through UART!!!

IS it that for C51 we have UART downloading but for S51 only SPI(and no UART downloading) even though it has dual UART!!!

Note
This message was edited to reduce width.

 You assume too much...

A generic 8051 has no download facility at all.
Therefore, the download facilities that you do find are entirely manufacturer and/or chip-specific.

Therefore you must read the Datasheet for the specifc device and not go making any assumptions based on what other devices may or may not do!

Look at the Key Parameters table in the 89S52 page on Atmel's site:
http://www.atmel.com/dyn/products/product_card.asp?
family_id=604&family_name=8051+Architecture&part_id=1918

It tells you that ISP is provided via SPI - it doesn't mention anything else (eg, UARTs) so you must assume that there is nothing else.

The datasheet describes two programming methods - Parallel and Serial (see p16).
It tells you that the Serial mode uses SPI - again, it doesn't mention anything else (eg, UARTs) so you must assume that there is nothing else.

On Atmel's product page for the 89S52 (see above), there is a link for 'Development Software: AT89ISP' - follow that link:

"The AT89ISP Software performs in-system programming (ISP) of Atmel AT89S/LP devices. It provides an intuitive interface for in-system programming that can be run from a personal computer."

can u send me the code that u used to download the hex file into the uC from the PC

 RE: 89C51 programmer circuit

Hi,

I'm designing a cool piece of kit to program 8051 and all derivatives.

The biggest feature is that it is guaranteed to be at least 10% faster and no less than 12.72% better than anything you could produce!

If you'd like me to send you the schematics and code to download the hex file from Windows, Linux, Unix, OSX or a Casio CFG-9860, please send me your request and I will consider your requirement.

 RE: 89C51 programmer circuit

Arthur Plank,
I have no need for your thingy, but could you, in a couple of weeks post how many requests you got. I am curious how mnay will bite.

PS, to let those interested contact you, you need publish your e-mail interest.

 Super new cool design for an 8051 programmer circuit

Hi all,

Development on my generic 8051 programmer has been continuing at a very good pace.

Design was completed a little earlier and coding finished very soon afterwards. I'm now concentrating on optimization.

After this, I will be running through to confirm the successful interation of components for every possible combination.

Should be finished by teatime!

In order to avoid the wrath of certain forum contributors (*), I would like to confirm that I have read all the documents for every derivative and am fully conversant with all the petty semantics of such things as integer promotion.

I feel so confident in my engineering capabilities that I consider it unnecessary to go through any beta releases or independent verification.

This project is the dog's rear wheels - It programs everything!

Don't accept any alternative - Alternatives are inferior.

Please send requests for project details via this thread.

(*) Any thoughts of the name Jack Sprat at this point in the text are purely coincidental

 RE: Super new cool design for an 8051 programmer circuit

From your great progress and benchmark scores, I take it that you have implemented the much valued gzip auto-decompress just-in-time downloader normally only available in some high-end commercial gang-programmers, to compress the transfer data by a factor 60-70%, and thereby gaining one or more of:
- reducing download transfer times
- allowing use of smaller chips
- circumvent code size restrictions of eval software
- emulating rom to ram or reverse depending on need
- transparently encapsulating chip differences by compressed emulation nano-kernel
- native marshaling between downloaded modules built by different vendors tools

I once planned to implement and sell a 32-bit ARM downloader with the above features, but found out that there where already some multi-architecture products on the market, for unifying PPC/ARM/MIPS/x86 and possibly 68k. However, I completely forgot to look into the lucrative 8-bit market, which its huge installed base and almost infinite number of derivatives...

 RE: Super new cool design for an 8051 programmer circuit

Hi Per Westermark,

The gzip routines I've developed actually borrow techniques from other lower grade developments.

I refer to it as maximum-compression-go-for-broke-level-10.

Other people sometimes refer to it by the not so catchy name of lossy compression.

I don't want to give too much away on this subject, because I'm considering patents, but I can divulge that it includes a certain degree of randomness - Since no two runs produce the same data, it makes it a right b***er to debug!

Oh well.

The AI component did originally included a good manners element (a classic English implementation).

Hi,

After a long time I came here. And it was a great entertainment reading the enitre thread. :)

Well for programmer, check if this helps.

http://www.technofreaks.org/topic32.html

But the best answer is already given by Erik and Andy which says

"Why, oh why does this activity still go on when there is a plethora of ISP chips available?"

Beginners, please don't just request for schematics and/or programmer details. Read datasheets. It says everything.

And moreover there are sites like http://www.google.com and http://www.wikipedia.org

Please use them before asking such questions.

Regards,
Shriram

Note: But what I feel is that people are reluctant to read datasheets :(

 RE: 89C51 programmer circuit

Reluctant?

They would rather die than read documentation in any form.

And most importantly: Everything must be free and working yesterday. Time is for data games. Money is for buying faster computers to play pirated games on. No resources of any kind may be spent on school work.

Arthur Plank, who made the statement is the creator of the gzip programmer. If he states something take it as you take statements from the creators of C. Who gives you the right to deny Arthur what you graciously bestow on K&R.

Erik

PS Arthur states "work in progress". Is your manual complete while you work on that project you never get finished because of you spending time on the language instead of the use thereof?

 RE: 89C51 programmer circuit

Oh boy...

Arthur Plank: "So nonsense such as plz is considered to be a non-conformance."

Jack Sprat: "I see no such statement in the manual. Chapter and verse, please."

Jack: You see no such statement in what manual???

A chip programmer incorporating a "maximum-compression-go-for-broke-level-10" download algorithm does not need a manual in the traditional sense. It is autodidactive, and autoconfiguring. It is enough that the chip programmer is stored in the same room as a power source (any energy source radiating more than 500uW/m2 for wavelenghts shorter than 950nm should suffice) and a handful of chips, for it to be able to correctly program and verify the chips. For about 90% of the chips, it is also able to download microcode patches to work around existing erratas.

Of course, if you do have suggestions for a manual, feel free to contribute. But before you do, please read this thread fully. Make sure that you understand the concept. Have a good time. Then either contribute, or move to other hunting grounds.

why file hex from keil some 89C51 programmer circuit can do a nother can't program

 The trouble with cheap programmers...

"why file hex from keil some 89C51 programmer circuit can do a nother can't program"

Why post in this thread, where it has nothing to do with the foregoing discussion?

One common reason is that some programmers are poorly made and don't properly understand the Intel Hex file format.
In particular, some poor implementations assume that the addresses in the Hex file must be in order - but the Intel Hex file format has no such requirement!

This has been discussed many times before - use the 'Search' facility!
