Answer to Question #154156 in C for Rakibul

Question

Write C code for Atmega32 programming for the following scenario:

Create a LED pattern with 8 LEDs which will represent the BCD value 0101 1000

Example:

The pattern will start to loop in the following order.

Loop:

{

First 0101 will be on and 1000 will be off for 2.5 seconds.

Next, 0101 will be off and 1000 will be on for 2.5 seconds.

Next, all 0101 and 1000 will be on for 2.5 seconds.

#include <avr/io.h>
#include <util/delay.h>

int main(void)
{
  DDRC = 0xFF; //Nakes PORTC as Output
  while(1) //infinite loop

    PORTC =0x5;
    _delay_ms(2500);
    PORTC= 0x00;
    _delay_ms(2500);
    PORTC =0x8;
    _delay_ms(2500);
    PORTC= 0x00;
      PORTC =0x5;
      PORTC =0x8;
       _delay_ms(2500);
  }
