[REQUEST] RGB Matrix panels and LED strip Support

[chef-wally]

Support for displaying output values to an RGB Matrix, LED strips for values/energy (%), individual LEDs, speakers for extra fun.

RGB Matrix: https://www.digikey.com.au/en/products/detail/adafruit-industries-llc/5036/14671681
LED strip: https://www.digikey.com.au/en/products/detail/adafruit-industries-llc/2540/9770543
LED: https://www.digikey.com.au/en/products/detail/sparkfun-electronics/11120/5673801
speakers: https://www.digikey.com.au/en/products/detail/adafruit-industries-llc/1314/7902282

example (this could be a matrix or led strip around an arcade cab):

What I've done so far:

#include <Adafruit_GFX.h>

#include <Adafruit_NeoPixel.h>

// RGB Matrix Configuration
#define MATRIX_WIDTH        64

uint8_t matrixClockPin      = 23;
uint8_t matrixLatchPin      = 6;
uint8_t matrixOutputEnable  = 9;

Adafruit_Protomatter rgbMatrix(
    MATRIX_WIDTH,

}

void loop() {
    updateRGBMatrix();
    updateNeoPixels();
}

Just in case this isn't already included in the discussion, individual LEDs are great to have too.
For example, this is common on older arcade games where the Player button will flash after inserting credits.
Or in lightgun games like Virtua Cop 2 where the police car lights flashing red and blue cause arcade buttons to also flash red and blue in sync (Model2 emulator).
I also believe this should be discussed here as it is not an issue: https://github.com/6Bolt/Hook-Of-The-Reaper/discussions

As I have announce many times, that LED controllers will come later. The Ultimarc products will come first, as they have sent me test hardware already. I can look at this, after that is done. I will leave this as an enhancement.

Also, if you guys want to open a discussions, please do. I will add any info that I can. Also, I can say how far away I am from implementing the LED stuff.

Just got this working, will upload fixed code to my repo as still some bugs.

That is cool and glad that you got it working. Did you have to put in a refresh delay? With LED matrix, I am guessing you didn't have too.

I am not too far away from LED/Light controllers. Once I finish the game files, I plan on getting them implemented. With the Ultimarc PacLED64 being the first.
