Development Support
Microchip offers a wide range of development tools that allow users to efficiently develop and
debug application code. Microchip’s development tools can be broken down into four categories:
1.
2.
3.
4.
All tools developed by Microchip operate under the MPLAB™ Integrated Development Environ-
ment (IDE), while some third party tools may not. The code generation tools include:
• MPASM
• MPLAB-C
• MP-DriveWay™
These software development programs include device header files. Each header file defines the
register names (as shown in the device data sheet) to the specified address or bit location. Using
the header files eases code migration, and reduces the tediousness of memorizing a register’s
address or a bit’s position in a register.
Tools which ease in debugging software are:
• PICMASTER
• ICEPIC In-Circuit Emulator
• MPLAB-SIM Software Simulator
After generating and debugging the application software, the device will need to be programmed.
Microchip offers two levels of programmers:
1.
2.
Demonstration boards allow the developer of software code to evaluate the capability and suit-
ability of the device to the application. The demo boards offered are:
• PICDEM-1
• PICDEM-2
• PICDEM-3
• PICDEM-14A
A full description of each of Microchip’s development tools is discussed in the
Tools”
from the Microchip web site (www.microchip.com) or from your local Microchip Sales Office.
Code development recommendations and techniques are provided in the
section.
Microchip offers other reference tools to speed the development cycle. These include:
• Application Notes
• Reference Designs
• Microchip web site
• Microchip BBS
• Local Sales Offices with Field Application Support
• Corporate Support Line
Additional avenues of assistance can be found in many Web User Groups including the MIT
reflector PIClist. The Microchip web site lists other sites that may be useful references.

section. As new tools are developed, product briefs and user guides may be obtained
Microchip strongly recommends that the supplied header files be used in the source
code of your program. This eases code migration as well as increases the quality
and depth of the technical support that Microchip can offer.
