 // You can reduce the memory footprint of this handler by declaring that there will be no pin change interrupts
 // on any one or two of the three ports.  If only a single port remains, the handler will be declared inline

// Note: in order to use MewPro Genlock Dongle reliably, THE FOLLOWING MODIFICATIONS TO STANDARD ARDUINO LIBRARY SOURCE IS
// STRONGLY RECOMMENDED:
//
//     1. hardware/arduino/avr/libraries/Wire.h
//            old: #define BUFFER_LENGTH 32                        -->   new: #define BUFFER_LENGTH 64
//     2. hardware/arduino/avr/libraries/utility/twi.h
//                 #define TWI_BUFFER_LENGTH 32                    -->   new: #define TWI_BUFFER_LENGTH 64
#include <Wire.h>
#if BUFFER_LENGTH < 64

// GoPro hardware emu (MewPro Genlock Dongle)
//
// To comple please use Arduino IDE 1.5.7 (or later) and PinChangeInt 2.40-rc2 (or later)
