The following shell commands are available:
* **turn_on:** Turn on all LEDs.
* **turn_off:** Turn off all LEDs.
* **wakeup:** Switch to normal mode.
* **sleep:** Switch to low power mode.
* **pwm:** Set individual PWM signal for a given channel.
* **grp_pwm:** Set global PWM signal.
* **blinking:** Set up values for blinking mode.
* **rgb:** Set PWM values for RGB.
* **rgba:** Set PWM values for RGBA.
* **ldr_state:** Set the LED driver output state for a given channel.
* **ldr_state_all:** Set the LED driver output state for all channels.
* **auto_increment:** Set an option for auto increment.
* **grp_ctrl_mode:** Set the group control mode.
* **run_demo:** Demonstration of all functions.
