6.2 Configure the Application Using MCC Melody

Follow the steps below to add and configure peripherals using MCC Melody:

  1. Click the Device Resources tab to view the drivers and libraries available for the device. Expand the Drivers drop-down and configure the following:

    • Expand the Timer drop-down and add TCB0
    • Expand the UART drop-down and add UART

  2. The peripherals added to the project will be visible in the Project Resources tab and the Application Builder view.

    Figure 6-8. MPLAB® Code Configurator—Project Resources

    In the following steps, configure the required peripherals.

  3. Configure the clock with the settings listed below by navigating to Project Resources > System > CLKCTRL:

    • Clock Selection: Internal high-frequency oscillator
    • Toggle off Prescaler Enable
    • Write Timebase to 20

  4. Configure TCB0 with the settings listed below by navigating to Project Resources > Drivers > Timer > TCB0:

    • Toggle on Enable Timer
    • Clock Selection: DIV1024
    • Counter Size: 16BITS
    • Timer Mode: INT
    • Requested Timeout (s): 1
    • Toggle on Generate ISR
    • Toggle on Enable Capture/Timeout Interrupt
