M5Atom Matrix, M5Unfied, controlling leds

HappyUser

Hi am stumped,
I just can't control the leds anymore.
This is my code, no led goes on.
Any suggestion where I am going terrible wrong?

#include <arduino.h>
 #include <M5Unified.h>
 #include <FastLED.h>
 #define NUM_LEDS 25
#define DATA_PIN 27
#define CLOCK_PIN 13
CRGB leds[NUM_LEDS];

void setup() {
auto cfg = M5.config();
cfg.serial_baudrate = 115200;
cfg.output_power = true;
M5.begin(cfg);
    //FastLED.addLeds<WS2812, DATA_PIN,GRB>(leds, NUM_LEDS);  // GRB ordering is assumed
    FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS); 

    for (int i=0;i<NUM_LEDS;i++) {leds[i]=CRGB::Red;};FastLED.show();


}

Hello @HappyUser

M5Unified has built-in LED support. My guess is that the two, M5Unified and FastLED, are 'fighting' for the LED. Have a look here. There is an example at the end of the page.

Thanks
