functions used to limit the amount of power used by FastLED

Function Documentation

uint8_t calculate_max_brightness_for_power_mW	(	const CRGB *	ledbuffer,
		uint16_t	numLeds,
		uint8_t	target_brightness,
		uint32_t	max_power_mW
	)

calculate_max_brightness_for_power_mW tells you the highest brightness level you can use and still stay under the specified power budget for a given set of leds.

It takes a pointer to an array of CRGB objects, a count, a 'target brightness' which is the brightness you'd ideally like to use, and the max power draw desired in milliwatts. The result from this function will be no higher than the target_brightess you supply, but may be lower.

uint8_t calculate_max_brightness_for_power_mW	(	uint8_t	target_brightness,
		uint32_t	max_power_mW
	)

calculate_max_brightness_for_power_mW tells you the highest brightness level you can use and still stay under the specified power budget.

It takes a 'target brightness' which is the brightness you'd ideally like to use. The result from this function will be no higher than the target_brightess you supply, but may be lower.

uint8_t calculate_max_brightness_for_power_vmA	(	const CRGB *	ledbuffer,
		uint16_t	numLeds,
		uint8_t	target_brightness,
		uint32_t	max_power_V,
		uint32_t	max_power_mA
	)

calculate_max_brightness_for_power_mW tells you the highest brightness level you can use and still stay under the specified power budget for a given set of leds.

It takes a pointer to an array of CRGB objects, a count, a 'target brightness' which is the brightness you'd ideally like to use, and the max power in volts and milliamps. The result from this function will be no higher than the target_brightess you supply, but may be lower.

Definition at line 80 of file power_mgt.cpp.

void delay_at_max_brightness_for_power ( uint16_t ms )

Similar to FastLED.delay, but pre-adjusts brightness to keep below the power threshold.

Deprecated:: this has now been rolled into FastLED.delay();

Definition at line 180 of file power_mgt.cpp.

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.

Deprecated:

use FastLED.setMaxPowerInVoltsAndMilliamps()

Definition at line 164 of file power_mgt.cpp.

void set_max_power_indicator_LED ( uint8_t pinNumber )

Select a ping with an led that will be flashed to indicate that power management is pulling down the brightness.

Deprecated:

use FastLED.setMaxPowerInMilliWatts

Definition at line 159 of file power_mgt.cpp.

void show_at_max_brightness_for_power ( )

Similar to FastLED.show, but pre-adjusts brightness to keep below the power threshold.

Deprecated:: this has now been moved to FastLED.show();

Definition at line 174 of file power_mgt.cpp.
