Help in LCD interfacing

"I am new to AVR Programming "

And you haven't noticed that an AVR is not an 8051-derivative, neither is it an 80251-derivative?

Also, Keil don't do any AVR tools!

"i have made my scope of study on 8051 family"

So what has the AVR got to do with it?
And why are you posting under 80251?

Please clarify: are you using an 8051 (or derivative) or aren't you?

If you are using an 8051 (or derivative) - ie, not an 80251 (or derivative) - please change the 'MCU' choice accordingly!

Dinosaur eh,

"Dinosaur eh"

Hmmm... spoken by someone just starting to use a 27C512 UV-EPROM:

Can anyone provide sample program for external memory

Of course you are a dinosaur. You did not immediately send full, complete well commented code that exactly fit the OPs requirements. You actually had the audacity to suggest "you can look that up in the C51 manual"

Only a true dinasour would dare to request that any OP actually did some work himself, let alone - do I dare say - read the manual.

Now Andy, however much you may be a dinasour how can you even THINK that 'please carify' deserves a response other than "Dinosaur eh"

PS I'm just as happy as Barney to be a dinasaur myself.

""MCS251 ... AVR ... 8051 ... i want to use the LCD for output so cud any one please help me little for LCD interfacing "

Of course, LCDs work the way they work irrespective of what processor you use, what language you use, what tools you use, etc, etc.

So what do you require that isn't already covered in the multitude of LCD tutorials that already exist all over the web?

do I dare say - read the manual

I don't think you do dare say that, manual reading being something you seem proud of not doing.

Jack,
If I need information I DO read the manual. I do, however, not read it every time one of your little 'utterings' come up, just to make YOU happy. If I can answer a question 'from memory' I do so and, if in doubt, I either do not answer or look it up.

The "lack of manual reading" you have accused me of in the past is NOT that I did not read, just that I did not read the same book as you. If you insist that before I answer anything in this forum, i read the EXACT source you use, please provide a full list of sources you rely on and I will give it a glance.

Hello sir .... i know i have made mistake cuz i didnt have to post my thread for C251 well sorry again cuz i have misplaced it .... the hole story is that i am using AT89C4051, (Default) and i can use it on my uVision2 with the AT89C51 but the problem is that i know about the interfacing the LCD with 8 bit and 4 bit but the problem is that i dont understand the ASM and the mostly code found on the internet is in ASM so could you please help me ...?

I know that i am Using one of MCS-51 family but have you any examples in C for 4 bit interfacing with LCD ?

You say, " i know about the interfacing the LCD with 8 bit and 4 bit "

You also say, "i know C programming"

If you know about LCDs, and you know 'C' programming, what specific problems are you having with implementing this in C51?

have you any examples
translated: "shut up and give me the code I have no intention of writing it myself"

Should I be wrong, I suggest the OP show his code.
