hi friend
i am working on atmega 32. i have small doubt when i am executing this small program by using code vision for generating code and i have used this hex file in proteus.
PROGRAM:
while (1)
{
// Place your code here

if(PORTC.0=1)
{
PORTB.0=0;

}
else
{
PORTB.0=1;
}

}
i have kept port c and port b as
PORTC=0x00;
DDRC=0x00;
and
PORTB=0x00;
DDRB=0x01;

the problem is that if i connect c(0) pin to +5v or gnd the output is same
it is giving always 1.
kindly plz me.....
this will be useful for my project
 

pull up resistor on the c.0 10k to +5V./on the c.0 is button?/
 
thanks dude for reply but it is not working when i kept a 10k resistor
 

if(PORTC.0=1)

this is a perfect example where your unwillingness to learn the very basics will come back and hunt you.

if u want u once try that one using code vision avr software and simulate in proteus.....
