Hi All,

I am trying to control 1050 leds with a teensy 3.2 and a prop shield (low cost). I tried all the examples and I use a good 50A power supply, but still the leds are giving me a beautiful organic but unwanted flickering effect.
Only if I put the project to 'CPU Speed: 8 MHz (reduce code size No USB)í the flickering is gone, but I canít use the USB anymore (which i need).
Is there a way to - or still use the USB with 8 MHz - or a solution to the flickering (like more powersupplies )?
I did try to lower the data rate to with ' FastLED.addLeds<APA102,11,13,RGB,DATA_RATE_MHZ(8) >(leds,NUM_LEDS); '
No luck.


#include <FastLED.h>

#define NUM_LEDS 1050

void setup() {
delay(2000); // sanity check delay
//FastLED.addLeds<APA102, BGR>(leds, NUM_LEDS);
FastLED.addLeds<APA102,11,13,RGB,DATA_RATE_MHZ(8) >(leds,NUM_LEDS);
pinMode(7, OUTPUT);
digitalWrite(7, HIGH); // enable access to LEDs

void loop() {
// Move a single white led
for(int n = 0; n < NUM_LEDS; n++) {
leds[n] = CRGB::White;
leds[n] = CRGB(0,0,0);
