#88157 - A51 to C51 interfacing Responding to: ???'s previous message |
Kurnia Brahmana said:
I have difficulties to call the A51 subroutine from C51. There is a whole chapter in the C51 Manual on interfacing C51 to Assembler. What particular problems are you having? The easiest way to do it is to create a "dummy" function in C51 with the necessary return value & parameter(s), then let the C51 compiler translate this into A51 source for you by using the SRC directive. You can then take the generated A51 source, confident in the knowledge that the compiler knows exactly how to generate correct code, and fill-in the body of the function with your own assembly code. See the C51 Manual for details of the SRC directive |
