This module adds support for the RGB LEDs found on the front panel of the Turris Omnia router. There are 12 RGB LEDs that are controlled by a microcontroller that communicates via the I2C bus. Each LED is described as a subnode of this I2C device. ^ permalink raw reply [flat|nested] 3+ messages in thread
