Hi,
hab mir ein 50LEDs Strang bestellt um mir adalight an dem TV zu machen,
jedoch hab ich nicht die WS2801 Chip version bekommen sondern die sm16716
da ich aber vom code schreiben und ändern zero plan habe bin ich im mom zimlich aufgeschmissen.
hab rausgefunden das man dafür den fastspi code nutzen kann jedoch lauft nix bei mir.

case 2: leds[iLed] = CRGB(0, 0, 128); break;
}
// and now, show your led array!
LEDS.show();
delay(10);
}
// fade up
for(int x = 0; x < 128; x++) {
// The showColor method sets all the leds in the strip to the same color
LEDS.showColor(CRGB(x, 0, 0));
delay(10);
}
// fade down
for(int x = 128; x >= 0; x--) {
LEDS.showColor(CRGB(x, 0, 0));
delay(10);
}
// let's fade up by scaling the brightness
for(int scale = 0; scale < 128; scale++) {
LEDS.showColor(CRGB(0, 128, 0), scale);
delay(10);
}
// let's fade down by scaling the brightness
for(int scale = 128; scale > 0; scale--) {
LEDS.showColor(CRGB(0, 128, 0), scale);
delay(10);
}
}
}
Ist das überhaupt richtig also der code brauch ich den und wenn ja könnte mir den jemand umschreiben das er auf meinem arduino uno r3 lauft mit 50 LEDs ?
MFG Danke
