TM16xxMatrixGFX.h

/*

TM16xxMatrixGFX.h - Adafruit GFX LED Matrix class for TM16xx.
The TM16xxMatrixGFX 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)   

The library supports modules with either 8x8 or 8x16 pixels 

Made by Maxint R&D. See https://github.com/maxint-rd/
