Setup Instructions
- Software Installation: Download and install the MPLAB Integrated Development Environment (IDE) from the official Microchip website. The PICKIT3 requires MPLAB IDE for operation. Ensure you have a compatible version installed.
- Connect to PC: Connect the PICKIT3 device to your computer using the provided USB cable. The device features a full-speed 12 Mbps USB interface.
- Connect to Target Microcontroller: Use the provided 6-pin cable to connect the PICKIT3 to your target PIC or dsPIC microcontroller. The connection is typically made via an RJ-11 compatible Microchip Debug connector on your target board.
- Power Supply: The PICKIT3 supports low voltage operation down to 2.0 volts, with a range of 2.0V to 6.0V. Ensure your target board's voltage is within this range. The PICKIT3 can power the target in some configurations, or the target can be self-powered.
- Driver Installation: Upon initial connection, your operating system may automatically install necessary drivers. If not, refer to the MPLAB IDE documentation for manual driver installation instructions.

Operating Instructions
The DollaTek PICKIT3 operates primarily through the MPLAB IDE. Follow these general steps for programming and debugging:
- Launch MPLAB IDE: Open the MPLAB IDE software on your computer.
- Select Programmer/Debugger: Within MPLAB IDE, navigate to the project settings or configuration options to select "PICKIT3" as your hardware tool.
- Configure Project: Ensure your project is correctly configured for your specific PIC or dsPIC microcontroller, including oscillator settings, memory allocation, and other device-specific parameters.
- Program Device: To program your microcontroller, compile your code within MPLAB IDE and then use the "Program" or "Make and Program Device" function. The PICKIT3 will transfer the compiled firmware to the target. The device supports programming up to 512K bytes of flash memory.
- Debug Device: For debugging, set breakpoints in your code within MPLAB IDE. Use the "Debug" functions (e.g., "Run," "Step Into," "Step Over," "Step Out") to control program execution on the target microcontroller. The PICKIT3 supports real-time execution and can freeze peripherals at breakpoints.
- Diagnostic LEDs:
- POWER LED: Indicates the PICKIT3 is receiving power.
- ACTIVE LED: Illuminates when the PICKIT3 is actively communicating with the target or the PC.
- STATUS/ERROR LED: Indicates the operational status or an error condition. Refer to MPLAB IDE for specific error messages.
- Firmware Upgrade: The PICKIT3 firmware can be upgraded from your PC or via web download through the MPLAB IDE. Follow the prompts within the software for firmware updates.
Maintenance
- Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Avoid liquid cleaners.
- Storage: Store the PICKIT3 in a dry, cool environment when not in use. Protect it from extreme temperatures and humidity.
- Cable Care: Inspect the USB and 6-pin cables regularly for any signs of damage. Replace damaged cables immediately to ensure reliable operation and prevent short circuits.
- Firmware Updates: Periodically check for and apply firmware updates through the MPLAB IDE to ensure optimal performance and compatibility with the latest microcontrollers and software features.
