MPLAB® Harmony v3 Peripheral Libraries on PIC32MX 470: Step 3
Configure Switch Button Pin with GPIO Interrupt Handler
In this step, the switch button will be configured as per the accompanying switch S1 design schematic of PIC32MX470 Curiosity Development Board.
In MPLAB® Harmony Configurator (MHC), select the Pin Settings tab and sort the entries by Ports names as shown.
Scroll down to the GPIO pin RD6 (Pin Number 54) in the Pin ID column and configure RD6 as an external interrupt pin for S1 switch functionality as shown below. Internal pull-up is enabled to avoid false edge detection as there is no external pull-up on the PIC32MX470 Curiosity Development Board.
Configure LED Pin
In this step, the user LED will be configured as per the accompanying LED0 design schematic of PIC32MX470 Curiosity Development Board.
Select the MHC Pin Settings tab and then scroll down to the GPIO pin RE4 (Pin Number 64) in the Pin ID column and configure RE4 as an output pin for LED1 functionality as shown.
The LED1 on the PIC32MX470 Curiosity Development Board is active low. Configure the LED1 in default OFF state by configuring the latch value to logic "High".
Rename the Default Main File
Under the Project Graph tab, click on System, and configure as below to give the name of your liking to the default template main file generated by MHC.
