Wire (I2C)

setSpeed()

Wire.setSpeed, setSpeed

Sets the I2C clock speed. This is an optional call (not from the original Arduino specs.) and must be called once before calling begin(). The default I2C clock speed is 100KHz and the maximum clock speed is 400KHz.

// SYNTAX
Wire.setSpeed(clockSpeed);
Wire.begin();

Parameters:

• clockSpeed: CLOCK_SPEED_100KHZ, CLOCK_SPEED_400KHZ or a user specified speed in hertz (e.g. Wire.setSpeed(20000) for 20kHz)
