# CONGIFURE YOUR BOARD HERE!
# LED strip configuration:
NUM_BALLS		= 41				# Number of balls on your board #CHANGED FOR XL
NUM_POS		= 41				# position of the ball
PIXEL_DENSITY	= 30				# This is how dense your strip is with pixels. 30 is the ideal density to buy (LEDs/meter)

PIXEL_RATIO		= PIXEL_DENSITY/30	# Needed for the odd strips like mine
LED_PIN        	= 18      			# GPIO pin connected to the pixels (18 uses PWM!).
LED_FREQ_HZ    	= 800000  			# LED signal frequency in hertz (usually 800khz)
LED_DMA        	= 10       			# DMA channel to use for generating signal (try 5)
LED_INVERT     	= False   			# True to invert the signal (when using NPN transistor level shift)
LED_CHANNEL    	= 0       			# set to '1' for GPIOs 13, 19, 41, 45 or 53
LED_STRIP      	= ws.WS2811_STRIP_RGB   # Strip type and colour ordering

# Define the rows the grid by defining the ball numbers.

# THIS IS IMPORTANT AND MAY BE DIFFERENT FOR YOUR BOARD!!!!!!

# This is the only way the program knows the correct LED numbers for each ball AND is essential to displaying text and things properly
