Microchip DV164035 Development Board: Overview and Application Guide
The Microchip DV164035 Development Board is a versatile and powerful platform designed for the evaluation and development of applications centered around Microchip's high-performance 8-bit PIC18 microcontrollers. This board provides engineers, students, and hobbyists with a robust environment to prototype and test ideas quickly, significantly reducing time to market for embedded systems projects.
Board Overview and Key Features
At its core, the DV164035 is engineered to host PIC18F MCUs from the 85-90 pin family. Its primary purpose is to serve as a foundation for developing and debugging code before deploying it to a custom PCB. The board's architecture is thoughtfully laid out to provide maximum flexibility.
A standout feature is the inclusion of a PIM (Processor Interface Module) header. This design allows developers to simply plug in different PIM modules, each housing a specific PIC18 microcontroller. This modularity means a single development board can support a wide range of PIC18F devices, making it an incredibly cost-effective and scalable solution for working with multiple chips.
The board is equipped with essential components for immediate operation, including:
On-board debugger/programmer, eliminating the need for external tools.
Crystal oscillator circuitry for accurate clock generation.
Peripheral interfaces such as buttons and LEDs for basic user interaction and testing.
Prototyping areas for adding custom components and circuitry.
Multiple connectivity options, including headers for serial communication (UART), SPI, and I2C, enabling easy interfacing with sensors, displays, and other external modules.
Application Guide and Development Workflow
Getting started with the DV164035 is a streamlined process:
1. Hardware Setup: Insert the desired PIM (e.g., PIC18F97J94 PIM) into the main board's socket. Connect the board to a PC via its USB port, which provides both power and a communication link to the integrated programmer/debugger.
2. Software Configuration: Using Microchip's free MPLAB X Integrated Development Environment (IDE), a new project is created. The specific PIC18 MCU on the PIM is selected as the target device. The IDE automatically detects the on-board debugger tool.
3. Application Development: Code is written in C or assembly. The vast array of I/O pins are broken out to headers, allowing developers to connect and control virtually any external device. The onboard LEDs and buttons are perfect for creating simple validation tests, such as reading an input and controlling an output.
4. Programming and Debugging: With a single click in the MPLAB X IDE, the compiled firmware is programmed onto the microcontroller. The integrated debugger allows developers to set breakpoints, step through code, and inspect variables, offering deep insight into the program's execution and drastically simplifying the process of finding and fixing bugs.
The board is ideal for prototyping a vast array of applications, including:
Industrial Control and Automation Systems
Advanced Sensor Nodes and Data Hubs
Consumer Electronics Interfaces
Complex Hobbyist and Robotics Projects
The Microchip DV164035 Development Board is an exceptionally flexible and efficient platform for harnessing the power of 8-bit PIC18 microcontrollers. Its modular PIM-based design, integrated debugging capabilities, and expansive I/O access make it an indispensable tool for rapidly progressing from concept to functional prototype, effectively bridging the gap between idea and implementation.
