Can anybody tell me how to combine both C and assembly in Uvision 3? I know something like we have to use SRC directive,asm and endasm for assembly. Suppose i want to perform some addition operation in assembly and i want to print the result using printf statement in C.How to get the register values to C variables?
"a mixed project which includes both C & Assembly source files in one file." You mean a single Project (eg, PROJECT.UV2) with both 'C' source files (*.C) and assembler source files (*.A51) It's easy: you just add all the files to the uVision Project, and uVision automatically knows to use the Compiler for 'C' source files, and the assembler for assembler files!

why not use a template as has been suggested ad nauseam "every week" when this issue comes up. Erik
