Smart medicine box

[parthshah08]

So, I am trying to turn the LED and a buzzer connected to specific ports on at a specific time each day.

Like say at 11 am every day for 10 minutes the buzzer and LEd turns on. I am new to Atmel studio programming and the board am using is A3BU Xplained.

So, I just need some help to get started with the coding and maybe some coding examples for the same, as there is a lot more further programming to be done to it.

Lets say, I have attached the LED and buzzer on the pins on Port2.

So, far I have done a bit of coding in Atmel and have came up with this,


#include <asf.h>

static void alarm(uint32_t time)
{
rtc_set_alarm(14);
while(true)
{
gpio_toggle_pin(J2_PIN0);
gpio_toggle_pin(J2_PIN1);

}
}


int main (void)
{
board_init();
pmic_init();
sysclk_init();
sleepmgr_init();
rtc_init();
rtc_set_callback(alarm);
cpu_irq_enable();
}

Still, not sure, about how to use call back function.

If someone can help.
