my "instance" of IOIO was created by BluetoothIOIOConnection, but this class doesnt contain any openAnalogInput function. I think I am missing something here. I see this function in IOIO class. How do I connect them to one object???
in SimpleIOIOApp\HelloIOIO I dont see any BT connection... בתאריך יום שבת, 4 באפריל 2015 בשעה 21:30:42 UTC+3, מאת Ytai: > > In what way can you not open an analog pin? > You shouldn't create another instance of IOIO other than the one that is > created for you by the application framework.
