Visdoll 4-pin WS2813 #275

QwertyInfo commented 6 years ago

Hi there! Just tried with WS2812 strip and all is workin as it should. Today i have a WS2813 4 pin Visdoll strip , 60led/m-5mt. Ho do i connect Di/d0 (data return) to work? Thank you

I dont have any WS2813 strips, but from what I could gather it should behave like WS2812B strips. The new chips have a backup data line which is labelled as DO, no connection is necessary. Your data line should be connected to DI. Again I got this info from the interwebs, dont know how accurate it is.

Ok i'm investigating today ho to solve this.Tried connecting only D1,only D0 and i sometimes have only 1 led on at the end of the strip. Power consumption is 0.186mA,the same i have when connecting a WS8212 in IDLE mode.Strip is just unboxed

Terrible reviews of this on Amazon! WS2813 is not supported in Adafruit NeoPixel library that McLighting is based on. These are supported in FastLED and NeoPixelBus libraries, saying timing is like WS2811 and at 800kHz. Sorry wish could help you better, don't have these LEDs.

Ok, I will try tomorrow. IMHO the ws2813 could be a very good strip, accordingly programmed. Let's try, brb

Hey! I managed to light up about 21 leds from the beginning of the strip. It's in a erratic behaviour,but now i know my strip is good ;)

Using NeoEsp8266Dma800KbpsMethod dma = NeoEsp8266Dma800KbpsMethod(NUMLEDS, 3) "numleds" in definitions.h is 300 (60 each meter x5)

Ok it works. declaring WS2812FX strip = WS2812FX(NUMLEDS, PIN, NEO_GRB +NEO_KHZ800)``, sharing ground with NodeMcu, and using D1(GPIO5) as Data Output on the board. Just connected D0 on the strip,leaving B0 unconnected. Power pins are connected from both ends of the strip.This strips eats more than 5Amps in white steady mode, turning central leds a little yellowish. No level shifter used,now i'll try to chain more strips !
