Paid sketch programmer wanted for LED strip effects

Hi. I am an L.A. based artist, who has found that I need help doing some customization sketches for an Arduino that can create color shits, chases, etc on an addressable LED strip.

I want to control a 2 meter 4 wire digital RGB strip (Flex Pixel #FLX775) from Elation Lighting https://www.elationlighting.com/flex-pixel-p40wp.

I have several of these strips installed in my loft by a lighting professional, powered by a DMX controller, but I have to boot up a laptop to run the DMX controller every time that I want the LED strips to light up. So to simplify this, I am trying to build an Arduino to do a series of color shifts and chases that will go on every time I turn power on to the lights and board.

I wired it up according to a NeoPixel diagram I found here: Basic Connections | Adafruit NeoPixel Überguide | Adafruit Learning System

I found the FastLED library and chose the simple Blink sketch. By trial and error, I found out that I replace the default NeoPixel code line with one of the choices: FastLED.addLeds<P9813, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS); // BGR ordering is typical, that I got my LED strip to blink red, as the sketch is intended.

Now I am looking for a sketch that will control all the 144 pixels in the strip and have them change colors, act as a chase lights or other color effects.

I have tried several that are posted but all seem to be coded for the NeoPixel strips. So am willing to pay someone to customize some sketches to make my Flex Pixel strips work.

Can you bee a bit more specific on what you actually want to do? e.g. each strip get's it's own arduino+powersupply, how should they het triggerd etc?

Why not just switch to neoPixels? As you can see they are very well supported.

Have you considered using an arduino to drive the dmx controller?

They seem to say “apa102 chips”, which I think makes them compatible with the adafruit “dot star” strips, hardware, and libraries. Those are supposed to be very close to the neopixel strips and libraries, but not quite.

Each of the 10 installed strips already has its own 5 v power supply. And I want to keep these strips and not replace with Neopixels.

On the idea of powering the strip's DMX controller via Arduino, that sounds fine. Is it possible? Can anyone point me to a wiring diagram and sketches to do this?

Is this a better solution than trying to find Arduino sketches to directly control these Flex Pixel strips?

It's not clear what you want to do. You want to keep the DMX controller or not? You want to replace the leds? No? you have led drivers? Maybe?
