asm code

[Rein]

Hello,

I'm working with a big8051 board.

When I compile asm routines , I have error messages asm instruction not found.
Example:

MOV P1MDOUT,#0FF

returns asm instruction not found while

MOV XBR2,#040

is recognized.

Where's the problem?

Thank you for helping me.

Hi,

In our compiler "#0FF" is invalid asm syntax, on the other hand, "#040" is valid asm syntax.

If you want to know details about asm syntax supported by mikroC PRO for 8051
it is recommended to study asm and lst files generated by compiler.

Best regards,
Marina

Try using MOV P1MDOUT,#0xFF
and MOV XBR2,#0x40

Hi,

Hexadecimal values needs to be in format "#0xFF", like mbrearley already said,
so please try to use:

Code: Select all

MOV P1MDOUT,#0xFF

instead of:

Code: Select all

MOV P1MDOUT,#0FF

Best regards,
