Hi,
I intend to mix some subroutines witten in assembly language into a
main program written in C language to program an EVB9S12NE64 kit
using CodeWarrior software..

could anyone tell me how?

is it only as the following examble:

if (i==0)
asm {
LDAA $2000
STAA $3000
.
.
}
else
asm {
LDAA $3000
STAA $2000
.
.
}

or there's other rules or WHAT?

thanx in Advance

=========================
I use the imagecraft HC12 compiler, and this is CLEARLY explained in the
help file. I have heard some complaints about how easy/hard codeworrier is to
use, but SURELY there is some mention of how to do this in the docs... Big
picture is inline in a c file, or add a .s file to the project. Know how to do an
assembler only program?

the manual {CodeWarrior}Help\PDF\Compiler_HC12.pdf does contain a
chapter called "High-Level Inline Assembler
for the Freescale HC(S)12" describing the syntax to be used.
The sample provided by the OP does actually compile just fine, so I'm
not sure where the problem is.

Daniel

int i;
void main(void) {

if (i==0)
asm {
LDAA $2000
STAA $3000
}
else
asm {
LDAA $3000
STAA $2000
}
for(;;) {} /* wait forever */
}

PS: In general I would use hex numbers in C syntax (0x2000 instead of
$2000) in C files, but the inline assembler also understands the $ syntax.

That's nice but I wanna know how variables created in C can be accessed
in Assembly

for ex:

int i[5];

asm{

LDD i

ADD #4

STD i

}

Is it valid??

This is explained in the High-Level Inline Assembler section of the
Codewarrior docs. Look through your start12.c file for some examples.
It would be nice if there were some more examples included with
Codewarrior.

Hello,
Yes, except that you have to use ADDD. So it would be:

int i[5];

void bar(void) {
asm {
LDD i
ADDD #4
STD i
}
}

Which will give you:
4: asm {
5: LDD i
0000 fc0000 [3] LDD i
6: ADDD #4
0003 c30004 [2] ADDD #4
7: STD i
0006 7c0000 [3] STD i
8: }
9: }
0009 3d [5] RTS

Erich

That's nice but I wanna know how variables created in C can be accessed in
Assembly

for ex:

int i[5];

asm{

ADD #4

STD i
