Analog inputs 0 - 5 can be used as digital pins 14 - 19.
HI
I need help making my analog pins work. WHen I use port manipulation, it works fine, however when I am not using port manipulation it does not work. What I want to do is a "Knight Rider" using PIN 3 as HIGH and PIN 7-19 as LOW. My code works fine until pin 13 and when it goes to the analog pins, it won't work....
here is the code:
#define x07x B10000000 //D 0-7 , B 8-13, C 0-5A DDR (i/o) , PORT (H/L)
#define x06x B01000000
#define x05x B00100000
#define x04x B00010000
#define x03x B00001000
#define x02x B00000100
#define x01x B00000010
#define x00x B00000001
int pinArray[] = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19};
int count = 0;
int timer = 50;
int timer2 = 13;
void setup(){
}
void loop() {
PORTD = x03x;
DDRD = x03x;
for (count=5;count<17;count++) {
pinMode(pinArray[count], OUTPUT);
delay(timer2);
pinMode(pinArray[count], OUTPUT);
delay(timer2);
pinMode(pinArray[count], INPUT);
delay(timer2);
}
