PoC.io.iic.BusController

GitHub Links

The I2C BusController transmitts bits over the I2C bus (SerialClock - SCL, SerialData - SDA) and also receives them. To send/receive words over the I2C bus, use the I2C Controller, which utilizes this controller. This controller is compatible to the System Management Bus (SMBus).
