Try issuing the command "seq s3s0" to see -something more familiar. - - -Note: the Pixel lightbar circuitry has three modes of operation: - -Unpowered - - When the host CPU is off (S5/G3), all power to the lightbar and its - controller circuitry is lost. - -On - - When the host CPU is on (S0) or suspended (S3), the lightbar is powered - again. After every power loss, it will need to be reinitialized by calling - lb_init() before it can be used. - -Standby - - The lightbar controller ICs can turn off all the LED outputs to conserve - power. This is the initial state when power is applied. You can turn the - LEDs off manually by calling lb_off(). When suspended, the controller will - respond to commands, but the LEDs aren't lit. Turn them on with lb_on(). |
