Problem with mspgcc assembler and macro.

[Claude Sylvain]

Hello,

 

My setup:

--------------

OS:                                       Windows XP

MSPGCC installer release:        030506

MSPGCC version:                    3.2.3

MCU:                                     MSP430F149

 

 

The problem is that the mspgcc assembler generate error when using the '&' symbol inside a macro like this one:

 

-------------------------------------------------------------------------------

.EQU P1OUT,  0x0021  ;Port 1 Output.

...............................................................................

 

.MACRO MY_MACRO

 

 mov.b &P1OUT,R5 ;Read port 1 outputs latch.

 

.ENDM

...............................................................................

 

    MY_MACRO        ;Calling the macro.

-------------------------------------------------------------------------------

 

The mspgcc assembler generate the following messages:

-------------------------------------------------------------------------------
misc.asm: Assembler messages:
misc.asm:198: Error: missing operand
misc.asm:198: Error: unknown _expression_ in operand &
misc.asm:198: Error: missing operand
misc.asm:198: Error: unknown _expression_ in operand &
-------------------------------------------------------------------------------

 

If I put the line "mov.b &P1OUT,R5" outside the macro, the assembler will not produce any error.

 

 

Is there a way to use instruction that use a '&' inside a macro ?

 

 

Claude.
