[Code Snippet] Talking to Arduino via OTG cable

[Dave Smart]

Hi All,

I got this Arduino demo working with AndroidScript's USB Espruino example and a Galaxy S3, with the following sketch running on an Arduino Uno board.   

These are the current default serial properties used by AndroidScript:

baud = 115200, databits = 8, stopbits = 1,  parity = none

// Sample Arduino sketch for use with usb-serial-for-android.

// Prints an ever-increasing counter, and writes back anything

// it receives.

static int counter = 0;

void setup() {

  Serial.begin(115200);

}

void loop() {

  Serial.print("Tick #");

  Serial.print(counter++, DEC);

  Serial.print("\n");

  if (Serial.peek() != -1) {

    Serial.print("Read: ");

    do {

      Serial.print((char) Serial.read());

    } while (Serial.peek() != -1);

    Serial.print("\n");

  }

  delay(1000);

}
