What: /sys/class/chromeos/<ec-device-name>/lightbar/brightness
Date: August 2015
KernelVersion: 4.2
Description:
Writing to this file adjusts the overall brightness of
the lightbar, separate from any color intensity. The
valid range is 0 (off) to 255 (maximum brightness).
What: /sys/class/chromeos/<ec-device-name>/lightbar/interval_msec
Date: August 2015
KernelVersion: 4.2
Description:
The lightbar is controlled by an embedded controller (EC),
which also manages the keyboard, battery charging, fans,
and other system hardware. To prevent unprivileged users
from interfering with the other EC functions, the rate at
which the lightbar control files can be read or written is
limited.
Reading this file will return the number of milliseconds
that must elapse between accessing any of the lightbar
functions through this interface. Going faster will simply
block until the necessary interval has lapsed. The interval
applies uniformly to all accesses of any kind by any user.
What: /sys/class/chromeos/<ec-device-name>/lightbar/led_rgb
Date: August 2015
KernelVersion: 4.2
Description:
This allows you to control each LED segment. If the
lightbar is already running one of the automatic
sequences, you probably won’t see anything change because
your color setting will be almost immediately replaced.
To get useful results, you should stop the lightbar
sequence first.
The values written to this file are sets of four integers,
indicating LED, RED, GREEN, BLUE. The LED number is 0 to 3
to select a single segment, or 4 to set all four segments
to the same value at once. The RED, GREEN, and BLUE
numbers should be in the range 0 (off) to 255 (maximum).
You can update more than one segment at a time by writing
more than one set of four integers.
What: /sys/class/chromeos/<ec-device-name>/lightbar/program
Date: August 2015
KernelVersion: 4.2
Description:
This allows you to upload and run custom lightbar sequences.
What: /sys/class/chromeos/<ec-device-name>/lightbar/sequence
Date: August 2015
KernelVersion: 4.2
Description:
The Pixel lightbar has a number of built-in sequences
that it displays under various conditions, such as at
power on, shut down, or while running. Reading from this
file displays the current sequence that the lightbar is
displaying. Writing to this file allows you to change the
sequence.
What: /sys/class/chromeos/<ec-device-name>/lightbar/userspace_control
Date: August 2015
KernelVersion: 4.2
Description:
This allows you to take the control of the lightbar. This
prevents the kernel from going through its normal
sequences.
What: /sys/class/chromeos/<ec-device-name>/lightbar/version
Date: August 2015
KernelVersion: 4.2
Description:
Show the information about the lightbar version.

Cirrus Logic Lochnagar Audio Development Board
Lochnagar is an evaluation and development board for Cirrus Logic
Smart CODEC and Amp devices. It allows the connection of most Cirrus
Logic devices on mini-cards, as well as allowing connection of
various application processor systems to provide a full evaluation
platform. Audio system topology, clocking and power can all be
controlled through the Lochnagar, allowing the device under test
to be used in a variety of possible use cases.
