Here is a small APP I wrote to drive APA102 LedStrips.

ESP8266 Hardware SPI is used to control the Strip.
I wrote an Android App to read images and send "lines" to the board via UDP.

Speed is really perfect for this kind of applications.

Excellent work as always. I am planning on adding a NEO Pixel channel to my lighting controller but only to set the brightness of the strip and color based on a couple of seekbars in B4A.

Have you a simple copy of the code that runs on the ESP simply to drive the strip and set color and brightness.
Had a look through and not sure what Library to use and how this connects to the ESP. I was hopping that the data line even though the strip runs on 5volts would work of the standard IO 3.3volt pin for data control.

Any pointers buddy would be brilliant.

Cheers

Have a look here : https://learn.adafruit.com/adafruit-dotstar-leds/overview

You will get codes example both for APA102 and NeoPixels strips

My strip does accept 3.3V on data to drive the leds. It was not garanted but it works !
