serialEvent4.cpp 239B
Raw Normal View History

T3.x(LC) - yield and eventResponder speedups if not used Code is setup that if there are no eventResponders that have registered to do interrupt calls, don't have the systic code in place to look for it. Also yield code. Now figures out if the user has any code that installs their own serialEventX methods, to call them, but if they have left the default weak pointer versions, to not call them in yield. Likewise will only look for eventRespnder events if the sketch has actually attached any events. If none of these conditions are true, yield will just check one flag and return.
