FastLED power management per controller pseudocode

gistfile1.txt

// this is all pseudocode and will probably not compile but it should give you an idea

// init...
// create your controllers
CLEDController controllerA = FastLED.addLEDs(LED_TYPE, DATA_PIN, COLOR_ORDER(ledsA, 0, NUM_LEDS_A);
CLEDController controllerB = FastLED.addLEDs(LED_TYPE, DATA_PIN, COLOR_ORDER(ledsB, 0, NUM_LEDS_B);

// loop....
// calculate power per controller
uint8_t scaleA = calculate_max_brightness_for_power_mW(controllerA.leds(), controllerA.size(), targetBrightness, MAX_POWER_MW_A);
uint8_t scaleB = calculate_max_brightness_for_power_mW(controllerB.leds(), controllerB.size(), targetBrightness, MAX_POWER_MW_B);

// show the controllers using their appropriate scales
uint8_t d = controllerA.getDither();
controllerA.showLeds(scaleA);
controllerA.setDither(d);

controllerB.getDither();
controllerB.showLeds(scaleB);
controllerB.setDither(d);
