7. 2. Button

It is a built-in BUTTON test on the OpenCR board.

7. 2. 1. Code

There are Push switches SW1 ~ 2 and Dip switches 1 ~ 2 in OpenCR. The pin number is

defined as below, so you can see the status of the current button when you input the data

of that pin.

It is a code that outputs the button input status in serial.

7. 2. 2. Result

OpenCR Arduino Test - BUTTON

7. 3. Buzzer

It is a BUZZER related test built in the OpenCR board and uses the Tone function of Arduino.

7. 3. 1. Code

#define BDPIN_DIP_SW_1 26

#define BDPIN_DIP_SW_2 27

#define BDPIN_PUSH_SW_1 34

#define BDPIN_PUSH_SW_2 35

}

Serial.print("dip_state = ");

Serial.print(dip_state, BIN);
