5.1 Microchip Studio with AVR64EA48 Curiosity Nano
Prerequisites
Microchip Studio
7.0.2594
or later installed
The
AVR64EA48 Curiosity Nano
Board is connected to Atmel Studio
7.0
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 Microchip Studio 7.0.
The page shown below will appear when
AVR64EA48 Curiosity Nano is connected to Atmel Studio
7.0.

Start creating a new project by clicking New → Project... or by using the
Ctrl+Shift+N shortcut, as shown in Figure 5-2.
Figure 5-2. Create New Project in
Microchip Studio
Select the GCC C Executable Project
template, as shown in Figure 5-3, type in the name of the solution and project (e.g.,
GETTING_STARTED and LED_TOGGLE), and click OK.Figure 5-3. New Project Wizard
Select AVR64EA48 as shown in Figure 5-4, and click OK.Figure 5-4. Device Selection WizardA new project with a main.c file associated will be generated in
Microchip Studio.
Replace the main.c file
with the following code snippet:
int main (void)
{
/* Configure SW0 as input */
PORTB.DIRCLR = PIN2_bm;
/* Configure LED0 pin as output */
PORTB.DIRSET = PIN3_bm;
/* Enable the internal pull-up for SW0 */
PORTB.PIN2CTRL |= PORT_PULLUPEN_bm;
while (1)
{
/* Check the status of SW0 *//* 0: Pressed */if (!(PORTB.IN & (PIN2_bm)))
{
/* LED0 on */
PORTB.OUTCLR = PIN3_bm;
}
/* 1: Released */else
{
/* LED0 off */
PORTB.OUTSET = PIN3_bm;
}
}
}
In the code
editor, the code will appear, as shown in Figure 5-5.Figure 5-5. Code Editor Window
Open project properties by clicking
Project → Properties or by using the ALT+F7 shortcut.
In the Tool view (see Figure 5-6), set Selected debugger/programmer to nEDBG and Interface to UPDI.Figure 5-6. Debugger and Interface for AVR64EA48
Build the project by clicking Build →
Build Solution or by using the F7 shortcut.
Program AVR64EA48 with the project code and start
debugging by clicking Debug → Start debugging and break or by using the ALT+F5 shortcut.
The application is programmed onto the device, and program execution will break in the
main() function.
Run the code by clicking Debug →
Continue or by using the F5 shortcut.
Verify that LED0 is lit when SW0
is pushed on the AVR64EA48 Curiosity Nano.
