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. WebThis function scans the selected I2C bus for available I2C slave device. //!

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

But it is also possible to access all devices on an adapter from userspace, through the /dev interface. You need to load module i2c-dev for this. Each registered I2C adapter gets a number, counting from 0. You can examine /sys/class/i2c-dev/ to see what number corresponds to which adapter.
