Hey guys!
I bought recently EasyVR 3.0 shield, and I’m having problems to use.
I made a simple project, just to test the shield with Arduino Uno, turning on or off two leds.
Before compile the code, I change the jumper to SW, and he led of shield turn off (It’s normal?).
But I’m getting the messages in my Serial Monitor:
Bridge not started!
EasyVR not detected!
EasyVR not detected!
EasyVR not detected!
EasyVR not detected!
Can someone help me, please?
Code:
#include "Arduino.h"
#if !defined(SERIAL_PORT_MONITOR)
#error "Arduino version not supported. Please update your IDE to the latest version."
#endif
#if defined(SERIAL_PORT_USBVIRTUAL)
// Shield Jumper on HW (for Leonardo and Due)
#define port SERIAL_PORT_HARDWARE
#define pcSerial SERIAL_PORT_USBVIRTUAL
#else
// Shield Jumper on SW (using pins 12/13 or 8/9 as RX/TX)
#include "SoftwareSerial.h"
SoftwareSerial port(12, 13);
