I think I got it. I tried to use a switch like in the c++ but each case relies on enum and I couldn’t figure out how to set each enum. I looked deeper into the crrcsim code and it is deep. I concluded that processing makes reading a serial port real easy in comparison. I took one more look at my last attempt in processing and changed i < 7 to i < 8 and now when I print the Channel[] values, they don’t shift in index position.
Now what I am going to try is to use the transmitter to control something in processing, like a joystick but not a joystick.
