3. Setup

3.1 Connecting to a PC

1. Connect one end of the provided USB cable to the USB port on the PICKit3 programmer.
2. Connect the other end of the USB cable to an available USB port on your computer.
3. The PICKit3 development tool has a built-in driver for high-speed USB communication. Your operating system should automatically detect and install the necessary drivers.

3.2 Connecting to the Target Board

The PICKit3 connects to your target PIC microcontroller board using the ICSP standard interface. Ensure correct pin orientation to prevent damage to the programmer or the target device.

1. Identify the ICSP header on your target PIC microcontroller board.
2. Connect the ICSP connection cable to the ICSP port on the PICKit3 programmer.
3. Carefully connect the other end of the ICSP cable to the ICSP header on your target board, ensuring that the pin assignments (VPP/MCLR, VDD, VSS, PGD, PGC) match correctly. Refer to your target board's documentation for specific ICSP pinouts.

3.3 Software Installation

The PICKit3 directly supports devices within Microchip's official MPLAB Integrated Development Environment (IDE). Download and install the latest version of MPLAB IDE from the Microchip website (www.microchip.com/mplab/mplab-x-ide) to utilize the full functionality of the programmer.

4. Operating Instructions

4.1 Programming Function

The PICKit3 can burn and write FLASH ROM, EEPROM, and configuration bits to your PIC microcontroller. This process is typically managed through the MPLAB IDE.

1. Ensure the PICKit3 is connected to both your PC and the target board.
2. Open MPLAB IDE and load your project.
3. Select the PICKit3 as your programmer/debugger tool within the MPLAB IDE settings.
4. Use the 'Program' or 'Build and Program' function within MPLAB IDE to transfer your compiled code to the target PIC MCU.

4.2 Simulation and Debugging Function

The PICKit3 supports various debugging methods, including full-speed running, single-step debugging, and breakpoint debugging, all performed via the USB interface for fast response times.

1. With the PICKit3 connected and selected in MPLAB IDE, switch to debug mode.
2. Set breakpoints in your code where you want execution to pause.
3. Start the debugger. You can step through your code line by line, observe variable values, and analyze program flow.
4. Utilize the 'Run' function to execute code at full speed until a breakpoint is hit or the program completes.

4.3 Firmware Upgrade

Microchip periodically releases new PIC models and updates to the ICSP device support list. The PICKit3 firmware can be upgraded to support these new models. The upgrade process is typically automatic when connected to an internet-enabled PC running the latest MPLAB IDE, which will prompt you for firmware updates.

5. Maintenance

• Keep the PICKit3 programmer clean and free from dust. Use a soft, dry cloth for cleaning.
• Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Avoid exposing the device to moisture or corrosive substances.
• Handle cables and connectors carefully to prevent damage.

6. Troubleshooting

6.1 Common Issues and Solutions

• Issue: PICKit3 not recognized by PC.
  Solution: Ensure the USB cable is securely connected. Try a different USB port or cable. Verify that the necessary drivers are installed (usually automatic with MPLAB IDE).
• Issue: Cannot connect to target device.
  Solution: Check all ICSP connections for correct pinout and secure contact. Ensure the target board is powered correctly. Verify that the target PIC MCU is supported by the current PICKit3 firmware and MPLAB IDE version.
• Issue: Programming/Debugging errors.
  Solution: Confirm that the correct PIC microcontroller is selected in MPLAB IDE. Check for power supply issues on the target board. Ensure your code is compiled without errors.
• Issue: Firmware upgrade failure.
  Solution: Ensure a stable internet connection. Restart MPLAB IDE and try the upgrade again. Consult Microchip's support resources for specific error codes.
