Definition: light_state.h:34
Interface to write LightStates to hardware.
Definition: light_output.h:12
Base class for all output components that can output a variable level, like PWM.
Definition: float_output.h:31
void set_pinb_pin(output::FloatOutput *pinb_pin)
light::LightTraits get_traits() override
void set_pina_pin(output::FloatOutput *pina_pin)
void write_state(light::LightState *state) override
This class simplifies creating components that periodically check a state.
Definition: component.h:283
void set_level(float state)
Set the level of this float output, this is called from the front-end.
Brightness of cold and warm white output can be controlled.
void current_values_as_cwww(float *cold_white, float *warm_white, bool constant_brightness=false)
This class is used to represent the capabilities of a light.
Definition: light_traits.h:11
const float HARDWARE
For components that deal with hardware and are very important like GPIO switch.
Definition: component.cpp:18
Implementation of SPI Controller mode.
