Hi, I am not a very good coder and mostly copy and paste so sorry if this is obvious, I would like to use @kripthor code for his MicLoc project but I keep getting the error " 'channel2sc1aADC0' is not a member of 'ADC_Module' "
I have arduino 1.8.5 and downloaded the latest teensyduino and have install the pedvide ADC library.
Here is the code
Code:
/* Example for analogRead
* You can change the number of averages, bits of resolution and also the comparison value or range.
*/
#include <ADC.h>
#define ADC_0 0
#define ADC_1 1
// Teensy 3.0 has the LED on pin 13
const int ledPin = 13;

digitalWrite(ledPin, LOW); // turn the LED off by making the voltage LOW

}
Any help would be great! Thanks
