Guru Meditation Error if more than 2 Pins/ 2 controller are used with filehandling
I used the examples from here https://github.com/FastLED/FastLED/wiki/Multiple-Controller-Examples
- FastLED's newest feature - HD mode for the APA102/SK9822/Dotstar LEDS
- High Bit Depth Gamma Correction Algorithm for APA102/Dotstar LEDs
- Is there an alternative to using two WS2811 ics to control RGBW channels [first image], and are there any adjustments needed for the current regulator circuit [second image] ?
- Frames getting stuck with ESP32 and 16 by 16 LED Matrix
- changing brightness of the individual led's?
- Arduino Due SPI to control LED strip(s)

Multiple RGB outputs
Sweet. Then pretty much any arduino or other microcontroller would take care of what you need. The strips only take one output pin plus power and ground so just about everything will work for driving them. They act like a long shift register so the single pin is all that's needed to load the full strip with whatever patterns you want regardless of the length. You just have to tell it how many LEDs there are in total is all. Check out the FastLED library. You can learn more about it there and/or install the library in the IDE by pressing "ctrl shift I" for windows or "command shift I" for mac and search for it in the upper search area and install it right there. It comes with working examples too so all you would have to do is install the library, load one of the new example sketches that came with it, and probably edit the example to change the NUM_LEDS count to match what you're working with.

Trying to use two ESP32 to connect to resolume over Artnet - Are the ESPs to weak for the project? (long)
Some libraries overdrive the leds slightly. They are still totally stable. They can be driven slightly out of spec. Use this library to drive them at 833 kHz. https://github.com/hpwit/I2SClocklessLedDriver

Two libraries to power your led projects
This is the library that I've used in all my projects. I know it's not technically FastLED. At least not yet. It's actually written by the same guy @u/Yves-bazin who made the 16 pin parallel i2s implementation of FastLED for the esp32. It has a plethora of new features and more stable signal. My favourite is the ability to choose the strip lengths and pins dynamically. I don't have to bake the pins into the source code but I can actually change them during runtime. This means I can save my settings to flash and reconfigure them over serial or a webserver. https://github.com/hpwit/I2SClocklessLedDriver

Pushing 1000 pixels over serial.
I’ll test this later today! Been looking at this library as well https://github.com/hpwit/I2SClocklessLedDriver

ESP32-MINI-1 Custom PCB interrupt issues?
Does this board has i2s in parallel? If yes https://github.com/hpwit/I2SClocklessLedDriver/tree/87a67af8b39090fe254a45308c72386e11bc85a6 using the fulldmaoption there is an example https://github.com/hpwit/I2SClocklessLedDriver/blob/87a67af8b39090fe254a45308c72386e11bc85a6/examples/FullBufferFastLED/FullBufferFastLED.ino You should not have any issue with interrupt

i2s show() speed?
Do have it do what you ask you need to have it full dma buffer that represents your strip. Look at the readme of this https://github.com/hpwit/I2SClocklessLedDriver towards the end. There is a mode that can Answer what you ask.

ESP32, SK6812, RGBW, multiple strips support
Hello you can try this https://github.com/hpwit/I2SClocklessLedDriver and if you need more than 16 strips https://github.com/hpwit/I2SClocklessVirtualLedDriver

Flickering
Are you using wifi with your leds ? How Manu strips do you have ? You can try this library https://github.com/hpwit/I2SClocklessLedDriver.

Scrolling with a single instruction. No memcpy nor redrawing. #hardwarescrolling ;)
Perhaps I'm reading it wrong, but I thought it would take no more RAM. It seems to treat each scanline as two sections, to create a circular buffer.
