Practice 2 #

Light up the LED Counter in simulator

• 0 to 9
• 9 to 0
• Speed of counting
• Count 0 to 5

CODE 0 to 9 and 9 to 0 #

void main (void) {
    DDRC.0 = 0;
    DDRA = 0xFF;

    while(1) {
        if (PINC.0 == 1) {
            int i = 0;

            while(i < 10) {
                PORTA = i;
                i++;
                delay_ms(50); // Speed 50 MS

                delay_ms(50); // Speed 50 MS
            }
        }
    }
}

Changes that count 0 to 5

while(i < 5) {
    PORTA = i;
    i++;
    delay_ms(50);
}
else {
    int i = 5;
	while(i >= 0) {
	    PORTA = i;
	    i--;
	    delay_ms(50);
	}
}

Algorithm that show Sum and Multiply of numbers and show on LED

We have 4 SW_SPDT

• A0 and A1
• B0 and B1
