13.4 MPLINK/MPLIB Linker/Librarian
MPLINK is a relocatable linker for MPASM and
MPLAB-C17 and MPLAB-C18. It can link relocatable
objects from assembly or C source files along with pre-
compiled libraries using directives from a linker script.
MPLIB is a librarian for pre-compiled code to be used
with MPLINK. When a routine from a library is called
from another source file, only the modules that contains
that routine will be linked in with the application. This
allows large libraries to be used efficiently in many dif-
ferent applications. MPLIB manages the creation and
modification of library files.
MPLINK features include:
• MPLINK works with MPASM and MPLAB-C17
and MPLAB-C18.
• MPLINK allows all memory areas to be defined as
sections to provide link-time flexibility.
MPLIB features include:
• MPLIB makes linking easier because single librar-
ies can be included instead of many smaller files.
• MPLIB helps keep code maintainable by grouping
related modules together.
• MPLIB commands allow libraries to be created
and modules to be added, listed, replaced,
deleted, or extracted.
13.5 MPLAB-SIM Software Simulator
The MPLAB-SIM Software Simulator allows code
development in a PC host environment by simulating
the PICmicro series microcontrollers on an instruction
level. On any given instruction, the data areas can be
examined or modified and stimuli can be applied from
a file or user-defined key press to any of the pins. The
execution can be performed in single step, execute until
break, or trace mode.
MPLAB-SIM fully supports symbolic debugging using
MPLAB-C17 and MPLAB-C18 and MPASM. The Soft-
ware Simulator offers the flexibility to develop and
debug code outside of the laboratory environment mak-
ing it an excellent multi-project software development
tool.
13.6 MPLAB-ICE High Performance
Universal In-Circuit Emulator with
MPLAB IDE
The MPLAB-ICE Universal In-Circuit Emulator is
intended to provide the product development engineer
with a complete microcontroller design tool set for
PICmicro microcontrollers (MCUs). Software control of
MPLAB-ICE is provided by the MPLAB Integrated
Development Environment (IDE), which allows editing,
“make” and download, and source debugging from a
single environment.
Interchangeable processor modules allow the system
to be easily reconfigured for emulation of different pro-
cessors. The universal architecture of the MPLAB-ICE
allows expansion to support new PICmicro microcon-
trollers.
The MPLAB-ICE Emulator System has been designed
as a real-time emulation system with advanced fea-
tures that are generally found on more expensive devel-
opment tools. The PC platform and Microsoft^® Windows
3.x/95/98 environment were chosen to best make these
features available to you, the end user.
MPLAB-ICE 2000 is a full-featured emulator system
with enhanced trace, trigger, and data monitoring fea-
tures. Both systems use the same processor modules
and will operate across the full operating speed range
of the PICmicro MCU.
13.7 PICMASTER/PICMASTER CE
The PICMASTER system from Microchip Technology is
a full-featured, professional quality emulator system.
This flexible in-circuit emulator provides a high-quality,
universal platform for emulating Microchip 8-bit
PICmicro microcontrollers (MCUs). PICMASTER sys-
tems are sold worldwide, with a CE compliant model
available for European Union (EU) countries.
13.8 ICEPIC
ICEPIC is a low-cost in-circuit emulation solution for the
Microchip Technology PIC16C5X, PIC16C6X,
PIC16C7X, and PIC16CXXX families of 8-bit one-time-
programmable (OTP) microcontrollers. The modular
system can support different subsets of PIC16C5X or
PIC16CXXX products through the use of
interchangeable personality modules or daughter
boards. The emulator is capable of emulating without
target application circuitry being present.
13.9 MPLAB-ICD In-Circuit Debugger
Microchip’s In-Circuit Debugger, MPLAB-ICD, is a pow-
erful, low-cost run-time development tool. This tool is
based on the flash PIC16F877 and can be used to
develop for this and other PICmicro microcontrollers
from the PIC16CXXX family. MPLAB-ICD utilizes the
In-Circuit Debugging capability built into the
PIC16F87X. This feature, along with Microchip’s In-Cir-
cuit Serial Programming protocol, offers cost-effective
in-circuit flash programming and debugging from the
graphical user interface of the MPLAB Integrated
Development Environment. This enables a designer to
develop and debug source code by watching variables,
single-stepping and setting break points. Running at
full speed enables testing hardware in real-time. The
MPLAB-ICD is also a programmer for the flash
PIC16F87X family.
