*
* Just connect up + 5 v and Gnd to give it power . And then 3 wires declared in the
* # define ' s below . Actual pin assignments can be changed in MAX7219_DEBUG section
* of configuration_adv . h
* Just connect up + 5 v and GND to give it power , then connect up the pins assigned
* in Configuration_adv . h . For example , on the Re - ARM you could use :
*
* # define M ax7219_clock 77
* # define M ax7219_data_in 78
* # define M ax7219_load 79
* # define M AX7219_CLK_PIN 77
* # define M AX7219_DIN_PIN 78
* # define M AX7219_LOAD_PIN 79
*
* First call Max7219_init ( ) and then there are a number of support functions available
* control the LED ' in the 8 x8 grid .
* Max7219_init( ) is called automatically at startup , and then there are a number of
* support functions available to control the LED s in the 8 x8 grid .
