5.1 MPLAB® X with AVR64DD32 Curiosity Nano

Prerequisites

MPLAB X installed

Workflow

Launch MPLAB X.
The page shown in Figure 5-1 will appear when AVR64DD32 Curiosity Nano is connected to MPLAB X.

Replace the main.c file with the following code snippet:

int main (void)
{
  /* Configure SW0 as input */
  PORTF.DIRCLR = PIN6_bm;

  /* Configure LED0 pin as output */
  PORTF.DIRSET = PIN5_bm;

  /* Enable the internal pull-up for SW0 */
  PORTF.PIN6CTRL |= PORT_PULLUPEN_bm;
	
  while (1)
  {
    /* Check the status of SW0 */
    /* 0: Pressed */
    if (!(PORTF.IN & (PIN6_bm)))
    {
      /* LED0  on */
      PORTF.OUTCLR = PIN5_bm;
    }
    /* 1: Released */
    else
    {
      /* LED0 off */
      PORTF.OUTSET = PIN5_bm;
    }
  }
}

Add #inlude<avr/io.h> in main.c. In the code editor, the code will appear as shown in Figure 5-9.

Build the code by clicking on Production → Clean and Build Main Project or by using the Shift + F11 shortcut.
Verify that LED0 is lit when SW0 is pushed on the AVR64DD32 Curiosity Nano.
