Dear all,
My project runs on 89c51 but I have added some features then I am using 89v51rd2b.here I write a header file"#include <P89V51Rx2.H>" and also select in keil then it shows errors like"error c202 undefined identifier....."

"error c202 undefined identifier....."

Means cursor pointing after clicking this error this variable is not defined.

and also your question is not that much clear...

#include <P89V51Rx2.H>"

make sure you have selected the correct device from nxp not from atmel in device setting and you can try #include<p89v51rd2.h>

 

[tapu]

Yes I have selected 89v51rd2 & write header as you writen but shows same error.

 

[ud23]

#include<philips/REG51F.h> try this header file.
