I love how easy it is to control global brightness using FastLED.setBrightness().
Now I’m working on a project that has two CRGB objects, on two separate Teensy 3.2 pins.
I’d like to be able to adjust brightness of each CRGB object, similarly to the global setBrightness() function.
Is there a current function available that could scale brightness levels of individual CRGB objects?

Hi Paul,
You will probably find the answer in this past post:

Specifically, look at this code example from Daniel Garcia:

example_individual_setBrightness.ino

#include <FastLED.h>

#define LEDS_SIDE_LEN 29
#define LEDS_SIDE_NUM 3
#define NUM_LEDS_LEFT (LEDS_SIDE_LEN*LEDS_SIDE_NUM)
#define NUM_LEDS_RGHT (LEDS_SIDE_LEN*LEDS_SIDE_NUM)

#define NUM_LEDS_CNTR 96

CRGB ledsLEFT[NUM_LEDS_LEFT];

I hope this helps

Perfect, thanks Gottfried!
