| H A D | slave-interface.rst | 2 Linux I2C slave interface description
7 Linux can also be an I2C slave if the I2C controller in use has slave
8 functionality. For that to work, one needs slave support in the bus driver plus
10 example for the latter is the slave-eeprom driver, which acts as a dual memory
12 EEPROM, the Linux I2C slave can access the content via sysfs and handle data as
19 e.g. sysfs I2C slave events I/O registers
34 I2C slave backends behave like standard I2C clients. So, you can instantiate
36 difference is that i2c slave backends have their own address space. So, you
38 instantiating the slave-eeprom driver from userspace at the 7 bit address 0x64
