FastLED.h
central include file for FastLED, defines the CFastLED class/object
set_max_power_in_milliwatts
void set_max_power_in_milliwatts(uint32_t powerInmW)
Set the maximum power used in watts.
Definition power_mgt.cpp:180
show_at_max_brightness_for_power
void show_at_max_brightness_for_power()
Similar to CFastLED::show(), but pre-adjusts brightness to keep below the power threshold.
Definition power_mgt.cpp:185
delay_at_max_brightness_for_power
void delay_at_max_brightness_for_power(uint16_t ms)
Similar to CFastLED::delay(), but pre-adjusts brightness to keep below the power threshold.
Definition power_mgt.cpp:191
calculate_unscaled_power_mW
uint32_t calculate_unscaled_power_mW(const CRGB *ledbuffer, uint16_t numLeds)
Determines how many milliwatts the current LED data would draw at max brightness (255)
Definition power_mgt.cpp:61
set_max_power_in_volts_and_milliamps
void set_max_power_in_volts_and_milliamps(uint8_t volts, uint32_t milliamps)
Set the maximum power used in milliamps for a given voltage.
Definition power_mgt.cpp:175
set_max_power_indicator_LED
void set_max_power_indicator_LED(uint8_t pinNumber)
Select a pin with an LED that will be flashed to indicate that power management is pulling down the b...
