Just recently, Atmel has finally launched a new version of IDE-Atmel Studio 7.0, which uses Microsoft's latest Visual Studio 2015 platform, which is reflected in speed, performance and code visual style It's so detailed, it's very easy to use, the following will combine the examples to introduceAtmelHow to use Studio 7.0.  

Step 1: Open Atmel Studio 7.0


Step 2: New construction project





Step 3: Select the chip model




Step 4: AddASFDriver library
 


Step 5: View ASF driver instructions
 


Step 6: Write the code
 
 
Source code:

#include <asf.h> // Include Atmel MCU software library header file

#define LED PIN_PC27 // Define the IO port used by LED as PC27
#define KEY PIN_PC01 // Define the IO port used by KEY as PC01

void port_init (void); // Declare the function body


        /************************************************************************/
// * IO initialization Initialization
        /************************************************************************/
        void port_init(void)
        {
                struct port_config config_port_pin;
                port_get_config_defaults(&config_port_pin);
                
config_port_pin.direction = PORT_PIN_DIR_OUTPUT; // Configure IO port direction as output
port_pin_set_config (LED, & config_port_pin); // Initialize LED corresponding IO port
                
config_port_pin.direction = PORT_PIN_DIR_INPUT; // Configure IO port direction as input
config_port_pin.input_pull = PORT_PIN_PULL_UP; // Configure IO port pull-up
                
port_pin_set_config (KEY, & config_port_pin); // Initialize the KEY corresponding to the IO port
                
        }

        /************************************************************************/
// * Main program
        /************************************************************************/

        int main (void)
        {
System_init (); // System initialization
                
                /* Insert application code here, after the board has been initialized. */
port_init (); // IO initialization
                
                while(1)
                {
If (port_pin_get_input_level (KEY) == 0) // Press KEY, LED corresponds to IO level = 0
                        {
                                port_pin_set_output_level(LED, 0);
                        }
                        else
                        {
                                port_pin_set_output_level(LED, 1);
                        }
                }
                
        }
  

Step 7: Compile and produce the burned file



Step 8: Burn the file to the development board
