Update and Configure an Existing MHC-based MPLAB Harmony v3 Project to MCC-based Project: Step 3

< Back to Lab Start

Next Step >



In this step, we will extend the MHC project by configuring a GPIO pin for the SW3 switch and user LED (LED3).

Step 3.1: Configure the Switch Button Pin

Configure the switch button, BTN3 pin, with a General Purpose Input/Output (GPIO) interrupt handler.

The switch button, BTN3, will be configured as per the design schematic of the Curiosity PIC32MZ EF 2.0 Development Board shown in Figure 1.

Open Pin Configuration under Plugins: to verify the pin configuration. Select the Pin Settings tab and sort (Order) the entries by Ports.

Scroll down to GPIO pin RJ6 (Pin #133) in the Pin ID column and configure RJ6 as a GPIO pin for SW3 switch functionality. An internal pull-up is enabled to avoid false edge detection as there is no external pull-up on the Curiosity PIC32MZ EF 2.0 Development Board.

Step 3.2: Configure the LED Pin

The user LED3 will be configured as per the design schematic of the Curiosity PIC32MZ EF 2.0 Development Board shown in Figure 4.

Select the Pin Settings tab and then scroll down to GPIO pin RJ3 (Pin #117) in the Pin ID column and configure RJ3 as an output pin for LED3 functionality.

Note: The LED3 on the Curiosity PIC32MZ EF 2.0 Development Board is active low. Configure the LED3 in the default OFF state by configuring the latch value to logic High.
