While I try to build a program with MPLAB the anwer is "Build Succeded" but I get the following warnings: Warning[215] E:\PIC\xxx.ASM 32 : Processor superceded by command line. Verify processor symbol. Message[301] E:\PROGRAMMI\MPLAB IDE\MCHIP_TOOLS\P16F84A.INC 35 : MESSAGE: (Processor-header file mismatch. Verify selected processor.) I declare the processor in the first line of program after comments in this way: list p=pic16F84A INCLUDE P16F84a.INC What is wrong? In building with MPLAB 5.0 this doesn' happen.
