I want to add Arduino DUE in this code.
// Arduino Uno, Duemilanove, LilyPad, etc
//
#elif defined(__AVR_ATmega168__) || defined(__AVR_ATmega328P__)
#define ALTSS_USE_TIMER1
#define INPUT_CAPTURE_PIN 8 // receive
#define OUTPUT_COMPARE_A_PIN 9 // transmit
#define OUTPUT_COMPARE_B_PIN 10 // unusable PWM
Code from library
