MPLAB ASM30 Assembler/Linker/

Librarian

MPLAB ASM30 is a full-featured macro assembler.

User-defined macros, conditional assembly and a

variety of assembler directives make the MPLAB

ASM30 a powerful code generation tool.

The accompanying MPLAB LINK30 Linker and MPLAB

LIB30 Librarian modules allow efficient linking, library

creation and maintenance.

Notable features of the assembler include:

• Support for the entire dsPIC DSC instruction set

• Support for fixed-point and floating-point data

• Available for Windows operating system

• Command Line Interface

• Rich Directive Set

• Flexible Macro Language

• MPLAB IDE compatibility

Notable features of the linker include:

• Automatic or user-defined stack allocation

• Supports dsPIC DSC Program Space Visibility

(PSV) window

• Available for Windows operating systems

• Command Line Interface

• Linker scripts for all dsPIC DSC devices

• MPLAB IDE compatibility

MPLAB SIM Software Simulator

The MPLAB SIM software simulator provides code

development for the dsPIC33F family in a PC-hosted

environment by simulating the dsPIC33F device on an

instruction level. On any instruction, you can examine

or modify the data areas and apply stimuli to any of the

pins from a file or by pressing a user-defined key.

The execution can be performed in Single-Step,

Execute-Until-Break or Trace mode. The MPLAB SIM

software simulator fully supports symbolic debugging

using the MPLAB C30 C compiler and assembler. The

software simulator gives you the flexibility to develop

and debug code outside of the laboratory environment,

making

excellent

multi-project

software

development tool. Complex stimuli can be injected from

files, synchronous clocks or user-defined keys. Output

files log register activity for sophisticated post analysis.

Besides modeling the behavior of the CPU, MPLAB

SIM also supports the following peripherals:

MPLAB Visual Device Initializer

The MPLAB Visual Device Initializer (VDI) simplifies

the task of configuring the dsPIC33F. MPLAB VDI

software allows you to configure the entire processor

graphically (see Figure 10-2). And when you’re done, a

mouse click generates your code in assembly or

‘C’ code.

MPLAB

VDI

performs

extensive

error

checking on assignments and conflicts on pins,

memories and interrupts, as well as selection of

operating

conditions.

Generated

code

files

are

integrated seamlessly with the rest of our application

code through MPLAB Project.

Detailed

resource

assignment

and

configuration

reports simplify project documentation. Key features of

MPLAB VDI include:

• Drag-and-drop feature selection

• One click configuration

• Extensive error checking

• Generates initialization code in the form of a

‘C’ callable assembly function

• Integrates seamlessly in MPLAB Project

• Printed reports ease project documentation

requirements

• MPLAB Visual Device Initializer is an MPLAB

plug-in and can be installed independently of

MPLAB IDE
