I am trying to use external voltage reference in Intel Galileo gen 2 operating in Arduino mode.
So I created a setup code like this:
void setup() {
// We'll send debugging information via the Serial monitor
Serial.begin(9600);
// If you want to set the aref to something other than 5v
analogReference(EXTERNAL); // use AREF for reference voltage
}
I selected the board as Intel Galileo Gen 2 in Tools option. When I compiled I am getting the following error:
LM35_temp_sensor.ino:21:19: error: 'EXTERNAL' was not declared in this scope
But when I change the board to Arduino Uno in Tools option, the program in compiling fine.
This means that Intel Galileo Gen 2 does not support external analog voltage reference?
