It will be very helpful if you are porting to a platform in a language other than C++. But if you are using C/C++, TPixy2.h is a good starting point. It uses the LinkType class to communicate with Pixy2. It assumes some member functions and an implementation of millis() and delayMicroseconds(), as shown in the header code below: |
