GENERAL: SRC DIRECTIVE

Information in this article applies to:

  • C166 Version 3.12
  • C51 Version 5.50
  • C251 Version 2.14

SYMPTOMS

For the "SRC" directive, the C166 compiler manual states that this directive cannot be used with µVision.  How is in-line assembly then added to a C source file?

CAUSE

There is a misprint in the manual that creates this misconception. What is actually meant is: there is no "compiler option" in the µVision interface. The SRC directive is active in the C166 Compiler.

RESOLUTION

Include the line:

#pragma SRC

in the top of your C source file. This generates an assembler file equivalent to your C code, in a new file with the same name as your C file but with an .SRC extension.

MORE INFORMATION

  • Refer to SRC in the C166 User's Guide.
  • Refer to SRC in the Cx51 User's Guide.
