I am interfacing an RFID reader (ID-12) with AT89C51. I am trying to code it in Keil using C language. But it gives me error:- "Attempt to redefine an already defined symbol". This is happening when I use 'sbit' to assign any variable to a port. Whenever this port is reffered to it causes an error..
Please help out with this coding...
