WebA bus means specification for the connections, protocol, formats, addresses and procedures that define the rules on the bus. This is exactly what I2C bus specifications define. The I2C bus uses two wires: serial data (SDA) and serial clock (SCL). All I2C master and slave devices are connected with only those two wires.

Turns out, we can change the baudrate on the Raspberry Pi with a simple parameter to the i2c_bcm2708 module shown below to something like 32KHz. Just unload the module and re-insert it. You can also verify the baudrate with a file in sysfs. Then, write something to the EEPROM. iseb training courses
