The AVR128DA48 Curiosity Nano Board connected to MPLAB X via the on-board USB connector, which is
connected to the embedded debugger. The kit will be powered by the USB, and the embedded
debugger will enable debugging and programming via the USB.
Workflow
Launch MPLAB X.
The page shown in Figure 5-1 will appear when AVR128DA48 Curiosity Nano is connected to MPLAB X.Figure 5-1. AVR128DA48 Curiosity Nano Page in MPLAB® X
Start creating a new project by clicking
File → New Project... or by using Ctrl+Shift+N shortcut, as shown in Figure 5-2.Figure 5-2. Create New Project in MPLAB® X
Select the Categories → Microchip
Embedded and Projects → Standalone Project template from Figure 5-6, and click Next.Figure 5-3. New Project Window
Select AVR128DA48 from Figure 5-4, and click Next.Figure 5-4. Device Selection Window
Then select the board and the desired compiler, if there are any.
Type in the name of the project (e.g.,
LED_TOGGLE) and the project location (e.g., C:\microchip), and click
Finish.Figure 5-5. Project Name and Location Selection
Window
Create a new main.c file
by clicking File → New File... or by using Ctrl+N shortcut, as shown in Figure 5-6.Figure 5-6. Create a New File in MPLAB® X
Select the Categories → C and
File Types → C Main File template from Figure 5-7, and click Next.Figure 5-7. New File Window
Type in the name of the file (e.g.,
main) and click Finish.Figure 5-8. File Name Window
Replace the main.c file
with the following code snippet:
int main (void)
{
/* Configure SW0 as input */
PORTC.DIRCLR = PIN7_bm;
/* Configure LED0 pin as output */
PORTC.DIRSET = PIN6_bm;
/* Enable the internal pull-up for SW0 */
PORTC.PIN7CTRL |= PORT_PULLUPEN_bm;
while (1)
{
/* Check the status of SW0 */
/* 0: Pressed */
if (!(PORTC.IN & (PIN7_bm)))
{
/* LED0 on */
PORTC.OUTSET = PIN6_bm;
}
/* 1: Released */
else
{
/* LED0 off */
PORTC.OUTCLR = PIN6_bm;
}
}
}
Add
#inlude<avr/io.h> in main.c. In the code editor, the code will
appear as shown in Figure 5-9.Figure 5-9. Code Editor Window
Build the code by clicking on Production
→ Clean and Build Main Project or by using Shift + F11 shortcut.
Program AVR128DA48 with the project code and start
debugging by clicking Debug → Debugging Main Project.
Verify that LED0 is lit when SW0
is pushed on the AVR128DA48 Curiosity Nano.
