User Manual

ST7 Assembler Linker

Introduction

Thanks for choosing ST7! This manual describes how to use the ST7 Assembler-Linker to

develop applications for ST7 microcontrollers. The assembly tools described in this book form a

development system that assembles, links and formats your source code.

The ST7 Assembler-Linker includes the following tools:

●

Assembler (ASM): translates your source code (.ASM) written in assembly language, into

object code (.OBJ) specific to the target machine and an optional listing file (.LST).

●

Linker (LYN): processes the object files (.OBJ) produced by the assembler, resolves all

cross-references between object files and locates all the modules in memory. The

resulting code is output in an object code file (.COD). In a second pass, the Assembler

uses these files to produce an object code file, map and listing with absolute paths.

●

Obsend (OBS): translates the object code file to produce the final executable in a default

format (.FIN) or other format that you specify (e.g. ST S-record, Motorola S-record, Intel

Hex...).

●

LIB (Librarian): The librarian enables you to store frequently used subroutines in one

location for use with any number of ST7 applications.
