LS100 brightness and other Problems

[skatehouse]

Hello! I use the Arduino Micro with LS100. Admittedly, I had original LS100s before, but they were too dark for me.
I have the 2812b and cut it to 2x27 + 2x15. What doesn't explain to me is the following:

If I put 84 LEDs on the channel, since there are 84 LEDs, the LEDs remain dark and don't light up at all.
With 135 LEDs it's fine.
What I then notice, however, is that the colors are slightly offset when I play an Ambilight test video.

2nd problem is with the brightness. Since the brightness is limited to 50%, I tried to increase it to 100%. Here too, all LEDs remain dark.

This is the original one:

`

#include <CorsairLightingProtocol.h>
#include <FastLED.h>
// Hint: The channels of the LS100 are swapped in iCUE, so the first channel in iCUE is here channel 2
#define DATA_PIN_CHANNEL_1 2
#define DATA_PIN_CHANNEL_2 3
#define BUTTON_PIN 4
// Hint: The ATmega32U4 does not have enough memory for 135 leds on both channels
CRGB ledsChannel1[135];
CRGB ledsChannel2[54];
CorsairLightingFirmwareStorageEEPROM firmwareStorage;
CorsairLightingFirmware firmware(CORSAIR_SMART_LIGHTING_CONTROLLER, &firmwareStorage);
FastLEDControllerStorageEEPROM storage;
FastLEDController ledController(&storage);
CorsairLightingProtocolController cLP(&ledController, &firmware);
CorsairLightingProtocolHID cHID(&cLP);
void setup() {
	FastLED.addLeds<WS2812B, DATA_PIN_CHANNEL_1, GRB>(ledsChannel1, 135);
	FastLED.addLeds<WS2812B, DATA_PIN_CHANNEL_2, GRB>(ledsChannel2, 54);
	ledController.addLEDs(0, ledsChannel1, 135);
	ledController.addLEDs(1, ledsChannel2, 54);
	pinMode(BUTTON_PIN, INPUT_PULLUP);
}
void loop() {
	static bool lightingEnabled = true;
	cHID.update();
	if (buttonClicked()) {
		lightingEnabled = !lightingEnabled;
		fill_solid(ledsChannel1, 135, CRGB::Black);
		fill_solid(ledsChannel2, 54, CRGB::Black);
		FastLED.show();
	}
	if (lightingEnabled && ledController.updateLEDs()) {
		FastLED.show();
	}
}
/**
 * Handle button of the LS100. The button is optional.
 *
 * @return true if the button was pressed and then released.
 */
bool buttonClicked() {
	static bool previousState = 1;
	bool state = digitalRead(BUTTON_PIN);
	if (previousState == 0 && state == 1) {
		previousState = state;
		return true;
	}
	previousState = state;
	return false;
}

Here the adpted one:

Maybe you have issues with your power supply. If you try to light up too many LEDs they turn off because there is not enough power available
