PICSTART Plus Overview

1.6 MPLAB INTEGRATED DEVELOPMENT ENVIRONMENT

The MPLAB desktop provides an environment for developing and debugging your application. PICSTART Plus is integrated into the MPLAB IDE.

This document covers the basic setup and operation of the PICSTART Plus device programmer, but it does not cover all functions of the MPLAB IDE. Read the MPLAB IDE documentation to get a full understanding of the features and debug capabilities of the MPLAB IDE.

1.7 MPLAB DEVELOPMENT TOOLS

The MPLAB IDE integrates several tools to provide a complete development environment.

• MPLAB Project Manager

The Project Manager is used to create a project and work with the specific files related to the project. When using a project, source code is rebuilt and downloaded to the simulator or emulator with a single mouse click.

• MPLAB Editor

The MPLAB Editor is used to create and edit text files such as source files, code and linker script files.

• MPLAB SIM Simulator

The software simulator models the instruction execution and I/O of the PICmicro MCUs.

• MPLAB ICD 2

Microchip’s In-Circuit Debugger that works with MPLAB IDE for PIC18FXXX devices.

• MPLAB ICE Emulator

The MPLAB ICE emulator uses hardware to emulate PICmicro MCUs in real time, either with or without a target system.

• MPASM Universal Assembler/MPLINK Relocatable Linker/MPLIB Librarian

The MPASM assembler allows source code to be assembled without leaving the MPLAB IDE. MPLINK creates the final application by linking relocatable modules from MPASM, MPLAB C17 and MPLAB C18. MPLIB manages custom libraries for maximum code reuse.

• MPLAB C17, MPLAB C18 and C30 C Compilers

The MPLAB C17, MPLAB C18 and MPLAB C30 C Compilers provide ANSI-based high level source code solutions. Complex projects can use a combination of C and assembly source files to obtain the maximum benefits of speed and maintainability.

• MPLAB PM3, PRO MATE II, PICSTART Plus and PICkit™ Programmers

Develop code with the simulator or an emulator, assemble or compile it, then use one of these tools to program devices. This can all be accomplished with the MPLAB IDE.

• Third Party Tools

Many other companies have development tools for Microchip products that work with the MPLAB IDE. Consult the Microchip web site for additional information.

3.8 ADDING FILES TO THE PROJECT

Step Four of the Project Wizard allow us to select files for the project. We do not have a source file yet, so we will use an MPLAB IDE template file. The template files are simple files that can be used to start a project. They have the essential sections for any source file, and have information in them that will help you write and organize your code. These files are the MPLAB IDE folder, which by default is in the Program Files folder on your PC. There is one template file for each Microchip PICmicro and dsPIC device.

Scroll to the Program Files folder on Drive C:, open it, and scroll down to the MPLAB IDE folder. Open the MPLAB IDE folder and scroll down to the Mchip_Tools directory. Open the Mchip_Tools directory and get a template from the Object folder in the Template folder, and choose the file named f452tmpo.asm.

If you installed MPLAB IDE in the default location, the full path to the file will be:

C:\Program Files\MPLAB IDE\MCHIP_Tools\TEMPLATE\Object\f452tmpo.asm
