29. ted It is entirely possible to write your complete project using C51 without ever resorting to assembler Even time critical code such as interrupt service routines can be optimised at the compilation stage so as to generate the most efficient code The PK51 Toolset also features a Macro Assembler which can be used to write or import assembler source files The environment Introduction supports linking of separate assembler and source files within the same project Variables may be passed between C and assembly modules and vice versa After the C51 and assembler source files have been compiled and linked together the resulting code can then be imported into the Software Simulator where it can be fully tested and debugged without the need for an actual target board The simulator displays code in both high level and or assembler making it possible to see exactly what assembly code the compiler has generated This testing is useful for verifying the operation of code and also when trying to find logical errors The Keil PK51 Toolset is now available in four different packages from an evaluation version to the fully unrestricted version A full upgrade path between versions is also available allowing you to evaluate the product in stages PK51 will allow you to Author code ANSI C Write code in assembly language Write code in Intel PL M Compile assemble and link both C and assembly language source files Verify corr
