I press connect in easyVR commander and "Could not detect device connected to port COM17". In the arduino 1.0 i use COM17 for programming arduino.
Is the USB cable still connected to the Arduino? There is no Serial.begin() statement in the setup() function, so the inability of the software to connect to the Arduino makes sense.
// PC UART Init
pinMode(0, INPUT); // sets the digital pin as input
pinMode(1, OUTPUT); // sets the digital pin as output
This is crap. Get rid of it. The hardware serial pins belong to the HardwareSerial instance, and should not be messed with.
