To write directly a register, use i2cset: Board $> i2cset -f -y Example: write 0xac in register 0x0f of the peripheral at address 0x5f on the bus 0: Board $> i2cset -f -y 0 0x5f 0x0f 0xac A write can fail if the register is in read only mode. Install the I2C tools (i2c-tools is a set of I²C programs that make it easy to debug I²C devices without having to write any code): sudo apt-get install i2c-tools sudo apt-get update At the command prompt type one of these depending on whether you are using the I2C0 or I2C1 port: sudo i2cdetect … The i2c-tools package contains a heterogeneous set of I 2 C tools for Linux: a bus probing tool, a chip dumper, register-level SMBus access helpers, EEPROM decoding scripts, EEPROM programming tools, and a python module for SMBus access. location, but doesn't actually write to that location.
