This library allows you to communicate with I2C / TWI devices. On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to ...
Wire.setClock() 修改I2C通信的频率,标准值是100KHz Description This function modifies the clock frequency for I2C communication. I2C slave devices have no minimum working clock frequency, however 100KHz is usually the baseline. Syntax Wire.setClock(clockFrequency) Parameters clockFrequency: the value...
