LED blinking AVR
Blinky Program for AVR LED is connected to PORTC_5 in sinking mode that is active low.
#include<avr/io.h> // Header file for basic avr input/output
#include<util/delay.h> // header file for delay generation
#define BV(x) (1<<x)
int main(void)
{
DDRC=0xFF; //portc declared as output
PORTC=0xFF; // PORTC is initially high to off the led initially
while(1==1) // infinite loop as 1 is always equals 1
{
PORTC=~(BV(5)); // led glow here
_delay_ms(1000); // one second delay
PORTC=BV(5); // led not glow here
_delay_ms(1000);
}
return 0;
}
