Hi,

Micro used: ST7FL35

Compiler and Assembler used: Cosmic

Memory Model used: MODMM

Does anyone have a sample assembly code for writing a function with 2 passing parameters and with a return value and made as global so that it could be called in one other file ????

Thanks,

Suganya

You can write a sample function in C, see the asm produced by the compiler for that, and go on from there.

Luca,

As suggested i wrote a sample C code and tried using the asm code in my assembly file but i get the following error in it.

symbol _Check_Sample_Assembly$L not defined (Debug\timer.o Debug\cstartup.o )

I have attached my project, kindly let me know how to write a assembly routine to pass arguments when the memory model is modmm ????

Regards,

Suganya.

I have analysed that shared sections ($L) are not getting created for the assembly code.

Any clue???
