# This is a test example for the Adafruit Trellis w/HT16K33

#   These displays use I2C to communicate, 2 pins are required to
#   interface

# This example shows reading buttons and setting/clearing buttons in a loop
#   "momentary" mode has the LED light up only when a button is pressed
#   "latching" mode lets you turn the LED on/off when pressed
#
#   Up to 8 matrices per I2C bus can be used but this example will show 4 or 1

MOMENTARY = 0
LATCHING = 1
# Set the mode here:
