Flashing the Software onto the Microcontroller

Overview

This guide explains how to flash the compiled software onto the microcontroller using MPLAB IPE v6.0 and a PICkit3 programmer.

Note: Previous BIRDS projects may have used different versions of MPLAB IPE. Ensure that your setup is consistent with your project’s requirements.

Before you start

Before you proceed, ensure:

  • You have MPLAB IPE v6.0 installed on your system.
  • You have a functioning PICkit3 programmer.
  • The microcontroller is properly mounted on the subsystem board.
  • The compiled .hex file is available.
  • The necessary connections between the PICkit3 and the board are correctly set up.

Flashing the Microcontroller

  1. Connect the PICkit3 to the board and computer.

    • Plug the PICkit3 into the appropriate programming header on the subsystem board.
    • Connect the PICkit3 to your computer via USB.

  2. Launch MPLAB IPE.

    • Open MPLAB IPE v6.0.
    • In the Device dropdown, select the correct PIC microcontroller model (e.g., PIC18F67J94).

  3. Establish communication with the device.

    • Click the Connect button.
    • Verify that MPLAB IPE successfully detects the microcontroller.

  4. Load the compiled firmware.

    • Click Browse in the Hex File section.
    • Navigate to and select the compiled .hex file.

  5. Configure programming settings.

    • Ensure Erase All Before Program is selected.
    • Verify that the correct voltage settings are applied (refer to board documentation).
    • Disable Code Protect options unless needed.

  6. Flash the microcontroller.

    • Click Program to write the firmware to the microcontroller.
    • Wait for the process to complete and check for success messages in the output log.

  7. Verify the flashed firmware.

    • Click Verify to ensure the program was correctly written.
    • If verification fails, check wiring and try again.

  8. Disconnect and test.

    • Close MPLAB IPE.
    • Disconnect the PICkit3.
    • Power up the board and check if the software is functioning as expected.
