I2C - Scan I2C devices
- AmebaD [ AMB23 / AMB21 / AMB22 / BW16 / BW16 type C / AW-CU488 Thing Plus / AMB25 ] x 1
The example will scan the I2C bus for devices that is connected to Ameba. When a device is found, it will be shown on the serial monitor with the address of the device.
Connect the I2C device to I2C_SDA and I2C_SCL of the board.
Open the example in “File” -> “Examples” -> “AmebaWire” -> “I2C_Scanner”.
When the I2C bus detect any I2C device, the serial monitor will show the address of the I2C device as shown below:
When there is no I2C device connected to the board, the Arduino IDE serial monitor will show the message below.
