Immediate adresses with expressions in inline assembler

[slarti]

hi group, it seems the inline assembler can't interpret something like struct { int baz; int foo; } bar[10]; #define OFFSET_FOO 2 __asm addd #bar + OFFSET_FOO ; I am getting a "C10000: Nothing more expected" which goes away when I remove the addition. Any hints how to make this assemble? regards, Mark

Hello,

Have you tried placing the expression between parenthesis?

Hello

Did you try

__asm addd #bar:OFFSET_FOO;

Extract from the Compiler_HC12.pdf:

The inline assembler enables you to specify an offset from the address of a variable in order to access the low word of a long or a float

variable: Offset = ":" ConstExpr.
Variable = Ident {"." Ident}.

Below are some examples (assuming all variables are long):
LDY @g:2 ; Load Y with ((address of g) + 2)
LDX g:2 ; Load X with the value stored there
LDD r.f:2 ; Load D with low word of field f.
