Linux I2C slave eeprom backend
|

|
==============================

This is a proof-of-concept backend which acts like an EEPROM on the connected
|
||
|
I2C bus. The memory contents can be modified from userspace via this file
|
||
|
located in sysfs:
|
||
|
|
||
|
/sys/bus/i2c/devices/<device-direcory>/slave-eeprom
|
||
|
|
||
|
As of 2015, Linux doesn't support poll on binary sysfs files, so there is no
|
||
|
notfication when another master changed the content.
