Need – reg51.h – file

[Shafie]

Hi, I am trying  Simple toll plaza system using low frequency RFID interfaced with 8051 microcontroller (AT89C51) project these days, but I have a small problem in the codings. I am using mikroC PRO for 8051 to write the programme, and in reg51.h header file I am using below codings – but it still show some errors which says as some identifiers redifined. I need some help here from you, can I get the same exact reg51.h file that you used for this project as the header file ?

 

 

THIS IS MY reg51.h FILE CODING

SOME IDENTIFIERS REDEFINED does not mean that the header file is faulty , it means you have some problem in source code , and even after all you have some problem shift to KEIL uVISION its much better than mikroC
