Due analog read #1740
Description
I'm trying to read multiple analog sensors with the Due board. Reading one sensor works fine, but when I try to read two or more, the device returns garbage. This same code works fine on the Uno. I found a web posting about this issue and it has a work around that doesn't seem to work anymore.
Also, analogReference() does not compile with the due.
Here's my code:
int a, b, c, d;
void setup()
{
Serial.begin(9600);
Serial.println("Program is Starting");
}
void loop()
{
a=analogRead(0);
delay(50);
a=analogRead(0);
b=analogRead(1);
delay(50);
b=analogRead(1);
c=analogRead(2);
delay(50);
c=analogRead(2);
d=analogRead(3);
delay(50);
d=analogRead(3);
Serial.print("Port 0 ");
Serial.println(a);
Serial.print("Port 1 ");
Serial.println(b);
Serial.print("Port 2 ");
Serial.println(c);
Serial.print("Port 3 ");
Serial.println(d);
delay(1000);
}
