I know ive been asking a lot the past few posts.
I feel as though im getting close. There is just a lack of knowledge on my own end to accurately trouble shoot these issues
Using the RGB_shades code and the Matrix test code FASTLed Provides ive come up with this and did some testing.
#include <FastLED.h>
#include <EEPROM.h>
#define LED_PIN 9
#define COLOR_ORDER GRB
#define CHIPSET WS2812B
#define BRIGHTNESS 64
// Params for width and height
const uint8_t kMatrixWidth = 26;
const uint8_t kMatrixHeight = 14;
const bool kMatrixSerpentineLayout = true;
// Pixel layout

With this code. It will only light up a grid that is the 26x 10 with RANDOM ones turned off.
When I modify the code by changing numbers in my table to anything above 319 it seems I can only control up to LED 64 in the row.
So 0-63 can be shut on and off at will by assigning it any number above 319
I have partial control and Partial display.
Anyone have any ideas?
