Hi,
If you copy pure_analog_pins.cpp and pure_analog_pins.h from
it will compile. Whether it will work is another matter - they may not be in that variant for a reason. good luck

analogRead(A9) generates an undefined reference to `analogRead(PureAnalogPin)' e… rror when compiled for the M4 core.
Setup: Giga R1 board library: 4.1.5
Sketch:
```
#include "Arduino.h"
#include "RPC.h"
#define SERVO_POT_1 A9
void setup() {
RPC.begin();
analogReadResolution(16); //GIGA has 16 bit ADC (0-65535)
}
void loop() {
int temp = analogRead(SERVO_POT_1);
}
```
