Hi gents. I have a question a weird gitter/flickering I'm trying to get rid of. I have multiple NodeMCUs LoLin V3 with WS2811 12V (the data line is 5V) they are all connected to the LEDs via a logic converter (https://www.ebay.ca/itm/292535444426) to drive the LEDs from the 3.3V of the NodeMCU to the 5V of the LEDs. They are connected to GPI02 pin (D4 in NodeMCU LiLon V3).NeoEsp8266Uart400KbpsMethod. The power supply is a lithium battery 12.2V at the time of the video (No low ampere or voltage issues)

  1. For some reason on some of the NodeMCUs NeoEsp8266Uart400KbpsMethod works and on some NeoEsp8266Uart800KbpsMethod. Any idea why is that? Took me long time to figure this out.
    NeoPixelBus<NeoRgbFeature, NeoEsp8266Uart400KbpsMethod> strip(PixelCount, PixelPin);
  2. The LEDs are flickering if the values that they are getting is bellow 200 on the RGB - it is done via RgbColor(r,g,b) and then strip.SetPixelColor(i, targetColor). Here is a short video of it happening: https://youtu.be/XXvQ7d8lKL0

Any help would be appreciated!

Hello all. Just found NeoPixelBus a few days ago and wanted to know if it is possible to control two strips at a time. Platform ESP32 using Arduino IDE 1.8.6. Whenever I try to define two strips, the example code won't work. I am also new to Gitter and don't know how to post code, or format this request..... Example of my strip definitions: NeoPixelBus<NeoGrbFeature, Neo800KbpsMethod> strip1(NUM_LEDS1, DATA_PIN1);
NeoPixelBus<NeoGrbFeature, Neo800KbpsMethod> strip2(NUM_LEDS2, DATA_PIN2);
