Summary

Provides resources on programming the LED ring on the Intel® NUC6CAY & NUC7ixBN when using Linux*.

Description

Need to know how to program the ring LED on Intel® NUCs when using Linux*.

Resolution

Resources to help you program the ring LED when using Linux:

Using WMI to Program the Ring and Button LEDs details two software layers:

  • A lower layer, which exposes the LED programming (method) interface in ACPI.
  • An upper layer, which exposes the WMI interface for invoking ACPI methods.

While the second (WMI) layer is specific to Windows*, the first layer (ACPI) is OS-independent. There are implementations that support the invocation of ACPI methods in Linux. Here's a place to start: a Linux kernel module that enables calls to ACPI methods through /proc/acpi/call.

The NUC Blog also has information for this: Linux Kernel Driver for NUC LED Control.
