#126362 - Refer the application notes for the P89V51RD2
Responding to: ???'s previous message
Hello Arvind.

First of all, answering like this:


I dont know how ... ???


and giving out difficult to understand statement like this:


but In other word I can say MCU are not any more for use.


is not going to get you detailed answers.

If you want detailed answers, ask detailed questions!


could you or any one please tell me whats this OSC frequency ... Is it internal or external in the circuit ... mine external OSC I m using is 12 MHz ...


As I mentiond in my original post:

You will have to adapt this to the P89V51RD2, if there are any
changes, mostly they may be minor.


The code I posted is for the P89C51RD2 NOT for the P89V51RD2, Jan's piece of code should work, you will have do a lot of study and use these as a basis to write your own code.

By the way using the IAP is not very difficult, preserverance will pay off.

Mr. Arvind Shrivastava since beggining you are asking vague questions.


His active participation indicates that he is genuinely interested in solving his problem, I think he is unable to convey is requirement clearly for us to understand.

Regards,
John.
