Neopixel and Controllino

[tobiasriss]

Hi there,

I am a little confused.

I want to control neopixels. Everything works with the Arduino MEGA 2560. But when I use the same program with Conntrollino MAXI, unfortunately no LED flashes. What am I doing wrong?

I have included a sample code:

#include <Controllino.h>

#include <Adafruit_NeoPixel.h>

#define PIN CONTROLLINO_D0

#define NUMPIXELS 40

Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

int pause=100;

void setup() {

pixels.begin();

}

void loop() {

pixels.setPixelColor(1, pixels.Color(0,255,0)); // Pixel1 leuchtet in der Farbe Grün

pixels.show();

delay (pause);

pixels.setPixelColor(2, pixels.Color(0,150,0));

pixels.show();

delay (pause);

pixels.setPixelColor(3, pixels.Color(0,50,0));

pixels.show();

delay (pause);

pixels.setPixelColor(4, pixels.Color(0,10,0));

pixels.show();

delay (pause);

pixels.setPixelColor(5, pixels.Color(0,1,0));

pixels.show();

delay (pause);

pixels.setPixelColor(1, pixels.Color(0,0,0));

pixels.setPixelColor(2, pixels.Color(0,0,0));

pixels.setPixelColor(3, pixels.Color(0,0,0));

pixels.setPixelColor(4, pixels.Color(0,0,0));

pixels.setPixelColor(5, pixels.Color(0,0,0));

pixels.show();

delay (pause);

}

Hi, do you have any progress so far?

Have you connected the stripe to the pin header? And interconnected the GND of CONTROLLINO and external 5V power supply?

Thanks,
