-    -------------------------------------------------------------------------
-    Steps to create a virtual display made up of a chain of panels in a grid
-    -------------------------------------------------------------------------
-
-    Read the documentation!
-    https://github.com/mrfaptastic/ESP32-HUB75-MatrixPanel-DMA/tree/master/examples/ChainedPanels
-
-    tl/dr:
-    
-    - Set values for NUM_ROWS, NUM_COLS, PANEL_RES_X, PANEL_RES_Y, PANEL_CHAIN_TYPE. 
-
-    - Other than where the matrix is defined and matrix.begin in the setup, you 
-      should now be using the virtual display for everything (drawing pixels, writing text etc).
-       You can do a find and replace of all calls if it's an existing sketch
-      (just make sure you don't replace the definition and the matrix.begin)
-
-    - If the sketch makes use of MATRIX_HEIGHT or MATRIX_WIDTH, these will need to be 
-      replaced with the width and height of your virtual screen. 
-      Either make new defines and use that, or you can use virtualDisp.width() or .height()
-
-*****************************************************************************/
-// 1) Include key virtual display library
-    #include <ESP32-VirtualMatrixPanel-I2S-DMA.h>
-
-// 2) Set configuration
-    #define PANEL_RES_X 64 // Number of pixels wide of each INDIVIDUAL panel module. 
-    #define PANEL_RES_Y 32 // Number of pixels tall of each INDIVIDUAL panel module.
-
-    #define NUM_ROWS 2 // Number of rows of chained INDIVIDUAL PANELS
-    #define NUM_COLS 2 // Number of INDIVIDUAL PANELS per ROW
-    #define PANEL_CHAIN NUM_ROWS*NUM_COLS    // total number of panels chained one to another
-
-    /* Configure the serpetine chaining approach. Options are:
-        CHAIN_TOP_LEFT_DOWN
-        CHAIN_TOP_RIGHT_DOWN
-        CHAIN_BOTTOM_LEFT_UP
-        CHAIN_BOTTOM_RIGHT_UP
-
-        The location (i.e. 'TOP_LEFT', 'BOTTOM_RIGHT') etc. refers to the starting point where 
-        the ESP32 is located, and how the chain of panels will 'roll out' from there.
-
-        In this example we're using 'CHAIN_BOTTOM_LEFT_UP' which would look like this in the real world:
-
-        Chain of 4 x 64x32 panels with the ESP at the BOTTOM_LEFT:
-
-        +---------+---------+
-        |    4    |    3    |
-        |         |         |
-        +---------+---------+
-        |    1    |    2    |
-        |  (ESP)  |         |
-        +---------+---------+      
-
-    */
-    #define VIRTUAL_MATRIX_CHAIN_TYPE CHAIN_BOTTOM_LEFT_UP 
-
-// 3) Create the runtime objects to use
-
-    // placeholder for the matrix object
-    MatrixPanel_I2S_DMA *dma_display = nullptr;
-
-    // placeholder for the virtual display object
-    VirtualMatrixPanel  *virtualDisp = nullptr;

-## Chained Panels example - Chaining individual LED matrix panels to make a larger panel ##
-
-This is the PatternPlasma Demo adopted for use with multiple LED Matrix Panel displays arranged in a non standard order (i.e. a grid) to make a bigger display.
-
-![334894846_975082690567510_1362796919784291270_n](https://user-images.githubusercontent.com/89576620/224304944-94fe3483-d3cc-4aba-be0a-40b33ff901dc.jpg)
-
-### What do we mean by 'non standard order'? ###
-
-When you link / chain multiple panels together, the ESP32-HUB75-MatrixPanel-I2S-DMA library treats as one wide horizontal panel. This would be a 'standard' (default) order.
-
-Non-standard order is essentially the creation of a non-horizontal-only display that you can draw to in the same way you would any other display, with VirtualDisplay library looking after the pixel mapping to the physical chained panels.
-
-For example: You bought four (4) 64x32px panels, and wanted to use them to create a 128x64pixel display. You would use the VirtualMatrixPanel class.
-
-[Refer to this document](https://github.com/mrfaptastic/ESP32-HUB75-MatrixPanel-DMA/blob/master/doc/VirtualMatrixPanel.pdf) for an explanation and refer to this example on how to use.
-
-
-### Steps to Use ###
-
-1. [Refer to this document](https://github.com/mrfaptastic/ESP32-HUB75-MatrixPanel-DMA/blob/master/doc/VirtualMatrixPanel.pdf) for an explanation and refer to this example on how to use.
-
-2. In your Arduino sketch, configure these defines accordingly:
-```
-#define PANEL_RES_X 64 // Number of pixels wide of each INDIVIDUAL panel module. 
-#define PANEL_RES_Y 32 // Number of pixels tall of each INDIVIDUAL panel module.
-
-#define NUM_ROWS 2 // Number of rows of chained INDIVIDUAL PANELS
-#define NUM_COLS 2 // Number of INDIVIDUAL PANELS per ROW
-
-#define PANEL_CHAIN NUM_ROWS*NUM_COLS    // total number of panels chained one to another
-
-#define VIRTUAL_MATRIX_CHAIN_TYPE <INSERT CHAINING TYPE HERE - Refer to documentation or example>
-	
-```
-VIRTUAL_MATRIX_CHAIN_TYPE's:

-
-
-3. In your Arduino sketch, use the 'VirtualMatrixPanel' class instance (virtualDisp) to draw to the display (i.e. drawPixel), instead of the underling MatrixPanel_I2S_DMA class instance (dma_display).
