Hi All, following on from my previous topic, I have one further issue when trying to compile code written for AVR arduinos on the SAMD Due.
I will include the Background and setup from my previous post for those who haven't read it. Otherwise, feel free to skip to the Problem
Background: I do a bit of sim racing and am building a button box where I want to use Sim Hub's base code for arduino and expand on it. Sim Hub only supports some of the arduinos but I would like to use Arduino Due as it has the most pins and also allows using Joystick library for native HID support as a game controller. However, Due is not an option in Sim Hub configurator. Sim Hub software has a GUI configurator which allows configuring various inputs and outputs of the arduino, which can then be directly uploaded to the arduino. You can also configure everything and open the sketch allowing you to modify the code and change the arduino target.
Setup: I have configured everything for Arduino Leonardo within the Sim Hub GUI and then opened up the code in the Arduino IDE to change the arduino from Leonardo to Due (since Due is not available within Sim Hub GUI).
Problem Compiling the code gives the following errors:

Ufortunately I was not able to upload the zipped 50+ Files in this project since I'm a new user and the forum doesn't allow me to.
Here are some snippets I believe are relevant. Feel free to request more.
SHFastIO.h:
#ifndef __SHFASTIO_H__

private:
uint8_t bit = 0;
uint8_t port = 0;
bool pinIsValid = false;
public:
bool isValid() {
return pinIsValid;
}
void begin(int pin) {
if (pin < 0) {
pinIsValid = false;
}
else {
pinIsValid = true;
bit = digitalPinToBitMask(pin);
port = digitalPinToPort(pin);
}
}
int digitalRead()

}

buttonLastState = getState(button.digitalRead());
shButtonChangedCallback = changedcallback;
if (buttonLastState)

}
uint8_t getPressed() {

if (buttonState != buttonLastState && buttonLastStateChanged - millis() > 50) {

Any help is appreciated.
Thank you!
