Hi, I've got a project containing a c source file and an a51 assembler file. I need to be able to call some of the asm routines from the C file. I'm after a tutorial describing what you need to do to export the required routines from the asm file and to make the call from the C source. I'd also like an example of how to cope with function arguments, too! And any other relevant stuff. I'm using the uVision/51 environment which comprises a Keil 8051 C complier (V5.20) which is 2K limited, and doesn't allow embedded ASM. Thanks for any advice. David
