Setting generate an assembly file

Select main.c, then right-click and then select Options For Filein the option box will pop Generate Assembler SRC Fileand Assemble SRC File` check black

The re-establishment project

• 1, will generate main.SRC file in Project \ Objects folder after compilation, the compiled file the same name as main.asm.

• 2, depending on the compilation mode, in KEIL installation directory under the table keil \ c51 \ lib \ in selecting the appropriate library files added to the project.

C51S.LIB - no floating point operations Small model

C51C.LIB - no floating point operations Compact model

C51L.LIB - Large model no floating-point operations

C51FPS.LIB - Small model with floating-point operations

C51FPC.LIB - Compact model with floating-point operations

C51FPL.LIB - Large model with floating-point operations

After the addition was complete as shown below:

• 3, adding the project delete main.c main.asm, you can compile.
