Chapter 2. Assembler Interfaces
2.1
INTRODUCTION
There are several interfaces with which you may use the MPASM assembler,
depending on the assembler version. These interfaces are discussed here.
When MPLAB IDE is installed, the windowed version of the MPASM assembler
(mpasmwin.exe) is also installed. In addition, the windowed version and the
command-line version (mpasm.exe) of the assembler may be obtained with the regular
and demo version of the MPLAB C18 C compiler.

MPLAB IDE INTERFACE
The MPASM assembler is most commonly used with the MPLINK linker in an
MPLAB IDE project to generate relocatable code. For more information on this use, see
“PICmicro Language Tools and MPLAB IDE”.
The assembler may also be used in MPLAB IDE to generate absolute code (without
the use of the MPLINK linker or MPLAB IDE project) by using the QuickBuild feature.
To do this:
1. From the MPLAB IDE menu bar, select Project>Set Language Tool Locations to
open a dialog to set/check language tool executable location.
2. In the dialog, under Registered Tools, select “Microchip MPASM Toolsuite”. Click
the “+” to expand.
3. Select Executables. Click the “+” to expand.
4. Select MPASM Assembler (mpasmwin.exe). Under Location, a path to the
mpasmwin.exe file should be displayed. If no path is displayed, enter one or
browse to the location of this file. By default, it is located at:
C:\Program Files\Microchip\MPASM Suite\mpasmwin.exe
5. Click OK.
6. From the MPLAB IDE menu bar, select Project>Quickbuild to assemble the
specified asm file using the MPASM assembler.
