Question
Given the C program using Timer 0 with the ATmega32. Answer the questions for parts a and b below.
#include <avr/io.h>
int main(void)
{
DDRC = 0xff;
TCCRO = 0x02;
TCNTO = -128;
while(1)
{
while (!(TIFR & (1<<TOV0)));
TIFR = (1<<TOVO);
TCNTO = -128;
PORTC = 0x10;
}
return 0;
}
а)
Which bit on PORTC is altered in the program?
b)
Exclude the overhead in the period time calculation. Assume fosc = 8 MHz. Show your work for
full credit.
What is the period (not half-period) of the square wave generated in this program?
