I²C Interface
The TiWi-uB1 EM board includes an I²C interface. The I²C
provides an interface between the TiWi-uB1
module and the on-board temperature sensor (U2), as well as other I²C compatible devices connected
by the two-wire I²C serial bus. External components attached to the I²C bus serially transmit and/or
receive serial data to/from the I²C on the TiWi-uB1 module through the two-wire I²C interface. The I²C
bus supports any slave or master I²C -compatible device.
shows an example of an I²C bus.
Each I²C device is recognized by a unique address and can operate as either a transmitter or a receiver.
A device connected to the I²C bus can be considered as the master or the slave when performing data
transfers. A master initiates a data transfer and generates the clock signal, SCL. Any device addressed
by a master is considered a slave. I²C data is communicated using the serial data (SDA) pin and the
serial clock (SCL) pin.
