This is a group for folks designing and programming embedded systems using the Rabbit Semiconductor C-programmable microcontroller. Rabbit Semi is a spin-off from Z-World who makes a variety of embedded modules and tools. This group is not affiliated with either Rabbit or Z-World, but is a user forum for sharing ideas, asking questions, flaunting knowledge, and other typical user group stuff. The Rabbit is a powerful uC, supported by a full-featured C-compiler.
Macro Math - Shawn - Jun 11 13:43:09 2009
I have a macro in assembly that I pass a number to. I can pass this number to the macro,
no problem, that works fine. The problem I run into is if I try to increment this number.
The code looks like this:
// this is in assembly!
#define macro1(datatest,bittest) $\
anothermacro(datatest,2*bittest) $\
anothermacro(datatest,2*bittest+1)
Inside my macro, I want to nest some other macros, in an attempt to make programming easier (but with tight timing). But when I compile, I get "unexpected token", and that error goes away when I remove the math that I apply to bittest.
Is there a way around this? Or am I seeing some other error?

I decided to just expand out my code a bit, and do this instead:
// this is in assembly!
#define macro1(datatest,bittest1,bittest2) $\
anothermacro(datatest,bittest1) $\
anothermacro(datatest,bittest2)
Not quite what I wanted, but good enough to get me by.

When I use macros in assembly, I sometimes put "0+macro" so that if the macro has
parentheses in it, it won't be misinterpret as reading from a memory address.
