Detailed Description

Base class for all output components that can output a variable level, like PWM.

Floating Point Outputs always use output values in the range from 0.0 to 1.0 (inclusive), where 0.0 means off and 1.0 means fully on. While using floating point numbers might make computation slower, it makes using maths much easier and (in theory) supports all possible bit depths.

If you want to create a FloatOutput yourself, you essentially just have to override write_state(float). That method will be called for you with inversion and max-min power and offset to min power already applied.

This interface is compatible with BinaryOutput (and will automatically convert the binary states to floating point states for you). Additionally, this class provides a way for users to set a minimum and/or maximum power output

Member Function Documentation

◆ get_max_power()

float esphome::output::FloatOutput::get_max_power ( ) const

Get the maximum power output.

Definition at line 14 of file float_output.cpp.

◆ get_min_power()

float esphome::output::FloatOutput::get_min_power ( ) const

Get the minimum power output.

Definition at line 22 of file float_output.cpp.

◆ set_level()

void esphome::output::FloatOutput::set_level ( float state )

Set the level of this float output, this is called from the front-end.

Parameters

state The new state.

Definition at line 24 of file float_output.cpp.

◆ set_max_power()

void esphome::output::FloatOutput::set_max_power ( float max_power )

Set the maximum power output of this component.

All values are multiplied by max_power - min_power and offset to min_power to get the adjusted value.

Parameters

max_power Automatically clamped from 0 or min_power to 1.

Definition at line 10 of file float_output.cpp.

◆ set_min_power()

void esphome::output::FloatOutput::set_min_power ( float min_power )

Set the minimum power output of this component.

All values are multiplied by max_power - min_power and offset by min_power to get the adjusted value.

Parameters

min_power Automatically clamped from 0 to max_power or 1.

Definition at line 16 of file float_output.cpp.

◆ set_zero_means_zero()

void esphome::output::FloatOutput::set_zero_means_zero ( bool zero_means_zero )

Sets this output to ignore min_power for a 0 state.

Parameters

zero	True if a 0 state should mean 0 and not min_power.

Definition at line 20 of file float_output.cpp.

◆ update_frequency()

virtual void esphome::output::FloatOutput::update_frequency ( float frequency )

inlinevirtual

Set the frequency of the output for PWM outputs.

Implemented only by components which can set the output PWM frequency.

Parameters

frequence The new frequency.

Reimplemented in esphome::ledc::LEDCOutput, esphome::libretiny_pwm::LibreTinyPWM, esphome::esp8266_pwm::ESP8266PWM, and esphome::rp2040_pwm::RP2040PWM.
