Hello,

I have implemented all the Circuit.
And now I am getting all the things right and I have programmed the MCU P89V51RD2 succesfully.

Thank You very much for all your support.

one more question appart:
I have parallel programmer for AT89S52 with SPI interface.
P89V51RD2 has also SPI interface.
Can I build a programmer P89V51RD2 For with SPI interface?
If it is possible then which software I need for Programming P89V51RD2 from LPT port?

----------
Thank You

Dear Sir,
I am not getting the P89V51RD2 programmed with that Circuit of AT89S52.

I have adopted all the process that You have told to me.

When I clicked on 'start' ,It display "reset device in to ISP mode Now" with red color, I pressed the Reset button to Reset P89V51RD2, here nothing happened.Why?
I am not using DTR pin of COM port and I am not using PSEN also.

Can you give me the sample code or Hex file to start with?
I was programming with attached asm file after converting it in to hex File.
plese Find the attachment.
Do I need any modification in it?

I have implenented that Circuit diagram.
The reset window is appearing.it is not get vanished.
For how much time Reset window should appear?

I am not getting device programmed.

please, Help me!!

Thank You....

Thank You very Much for Your reply and suggestions.

I have the 8051 board with serial Inerface.Here I am attaching the Circuit diagram for the Connection of MCU AT89S52 with RS-232 port.
Here the Serial port is used for Communication with MCU AT89S52(Not For programming).
I want to replace AT89S52 with P89V51RD2 for programming it.
Can I program P89V51RD2 with Same circuit diagram by replacing AT89S52?

 

Thank You...........
