calculate_unscaled_power_mW() [2/3]

fl::u32 calculate_unscaled_power_mW

(

fl::span< const CRGB >

leds

)

Determines how many milliwatts the current LED data would draw at max brightness (255)

Parameters

ledbuffer	the LED data to check
numLeds	the number of LEDs in the data array

Returns

the number of milliwatts the LED data would consume at max brightness

Parameters

leds	span of LED data to check
