Write an interrupt handler for the ADC complete interrupt i

Write an interrupt handler for the ADC - complete interrupt in C. The ISR should store the 10-bit conversion result into a voltage global called temp using atmega328p?

Solution

#include<avr\\io.h>

#include<avr\\interrupt.h>

ISR(ADC_VECT)

{

PORTD = ADCL;

PORTB = ADCH;

ADCSRA | = (1<<ADSC);

}

int main(void)

{

DDRB = 0XFF;

DRRD = 0XFF;

DDRA= 0;

SEI();

ADCSRA = 0X8F;

ADMUX = 0XC0;

ADCSRA | = (1<<ADSC);

WHILE(1);

RETURN 0;

}
