ADC interface with atmega32 with two sensors

[s.manisrinivas]

HI friends ,

  I need help from you that, I am using ATmega32 avr development board for ADC multiple channels  and i am using two POT sensors.What is my doubt is  I want a small delay after two channel conversions,say delay is 2 sec (for example).After every delay conversions have to display.

I tried but i cannot make delay,for i used timer buts its vain.so, please help me guys

 

here is my code.

#include<avr/io.h>

#define LED PD4 

 

int main()

{

uint8_t timerOverflowCount=0;

DDRD=0xff;         //configure PORTD as output

TCNT0=0x00;

TCCR0 = (1<<CS00) | (1<<CS02);

 

while(1)

{

while ((TIFR & 0x01) == 0); 

 TCNT0 = 0x00;

 TIFR=0x01; //clear timer1 overflow flag              

timerOverflowCount++;

if (timerOverflowCount>=6)

{

PORTD ^= (0x01 << LED);

timerOverflowCount=0;

}

}

}

Hi there

Could you please share what output are you expecting from the above code.

According to me the LED should remain ON continuously without blinking with any specific delay.

if you are using AVR studio then in AVR studio you get built in delay function

_delay_ms() or _delay_us()
