/*

TM16xxMatrix.h - LED Matrix class for TM16xx.
The TM16xxMatrix class supports LED matrices of various sizes to be connected
to a TM16xx chip, such as TM1640 or TM1638. 

These are the resolutions supported by the most popular TM16xx chips:
   TM1637  8x6  (common anode)
   TM1638  10x8  (common cathode)
   TM1640  8x16  (common cathode)
	 TM1668  10x7  (common cathode)
