Hi all, can any one tell me the way how to mix c and assembly programing....... i know one way of inline programming i.e.
....... ....... C code.... ..... .....
#pragma asm ........ assembly code.... ........ #pragma endasm
but this type of file written cannot be included in any other file......
i have used IAR assembler for other microcontroller, in which writting
asm ("assembly code");
was working perfectly......
i dont know wether keil supports this.... if yes than what prototype file has to be included for this......
Any help is appriciated....
Thanking You, Pranav Saraswala.
"for the variable to be passed, should declared as global"
Of course. But you can still also pass values in parameters, and use the function's return value.
"is there any document which gives explanation of all this things"
Of course there is - it's called the Manual.
There is a chapter specifically titled, "Interfacing 'C' and Assembler" - guess what that's all about...
You can also do as Erik suggested: write a simple 'C' "skeleton" with examples of all these things (parameter passing, return value, accessing globals), then compile it with the SRC option and look at the generated assembler. Then follow the compiler's example.
The SRC option is, of course, described in the Manual.
