B4R Library rAdafruitNeoPixel

Wrapper for this library: https://github.com/adafruit/Adafruit_NeoPixel
Library for controlling single-wire-based LED pixels and strip.

Example:

Sub Process_Globals
   Public Serial1 As Serial
   Private pixel As AdafruitNeoPixel
   Private timer1 As Timer  
   Private n As Int
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("AppStart")
   pixel.Initialize(16, 6, pixel.NEO_GRB)
   timer1.Initialize("timer1_Tick", 500)
   timer1.Enabled = True
End Sub

Sub Timer1_Tick
   n = (n + 1) Mod 16
   pixel.SetPixelColor(n, 0, 150, 0)
   pixel.Show
End Sub

It works just PERFECT!!! time to do some voodoo!!!!( meaning, tested with UNO, now testing with ESP)

 

[Cableguy]

VOODOO is working too!!!
(I mean, it works on ESP too!!)

Post a picture of the LEDs...

 

[Cableguy]

I will implement some anims later today and post them... I just need to find some cool 5x8 pixel art!

 

[Cableguy]

well, not a cool 8x5 pixel art, but something to show...

I adapted the remote config example in order to show the "Wifi waves" when it enters AP mode.

here's my 8X5 neoPixel board:

Nice! I had been away from B4R for several months and am glad to see two new libraries (this one and rNSRainbow) for use with WS2812B LEDs. Thanks! and thank you Cableguy too for your code. Now I need to build something.

 

[Robert Gately]

With the rAdafruitNeoPixel library, it does not seem possible to change the color of all leds at once, unless I change them all individually using a For loop and then use Pixel.Show. Let's say I want all of the LEDs to Red. Is there a simpler way to do this than changing them individually in a loop? With Cableguy's WS2812 code module it is possible to change all LEDs at once by using "-1" instead of the individual LED number.

Thanks for any help!

 

[Erel]

You will need to use a for loop. It will be very fast.

You will need to use a for loop. It will be very fast.

Thanks.

I think I'll go with the rNSRainbow library. It seems to use a little less memory than the Adafruit NeoPixel library and allows me to use more than just one pin.

Would this lib work with this led strip? https://ru.aliexpress.com/item/1m-4...ck-White-PCB-30-60-144-leds-m/2036819167.html

 

[Erel]

I'm not sure. I recommend you to order the shortest strip and test it.

@GanjaKyp Yes I can confirm WS2812 are the LED drivers used by NeoPixel library.

@GanjaKyp Yes I can confirm WS2812 are the LED drivers used by NeoPixel library.

The issue is, some vendors sell "WS2812 compatible driver" led strips, which can sometimes have different timings

 

[Ilya G.]

Yes it work Is it library compitable with B4J?

 

[Cableguy]

No, arduino is a very very different platform.
You can however, use b4j to create a program to interact with the Arduino or an esp2866 board using serial or WiFi

I have updated the library to version 1.01 using https://github.com/adafruit/Adafruit_NeoPixel version 1.1.8

ESP32 are now supported.
