  23. /**
  24. * This module is off by default, but can be enabled to facilitate the display of
  25. * extra debug information during code development.
  26. *
  27. * Just connect up 5V and GND to give it power, then connect up the pins assigned
  28. * in Configuration_adv.h. For example, on the Re-ARM you could use:
  29. *
  30. * #define MAX7219_CLK_PIN 77
  31. * #define MAX7219_DIN_PIN 78
  32. * #define MAX7219_LOAD_PIN 79
  33. *
  34. * max7219.init() is called automatically at startup, and then there are a number of
  35. * support functions available to control the LEDs in the 8x8 grid.
  36. *
  37. * If you are using the Max7219 matrix for firmware debug purposes in time sensitive
  38. * areas of the code, please be aware that the orientation (rotation) of the display can
  39. * affect the speed. The Max7219 can update a single column fairly fast. It is much
  40. * faster to do a Max7219_Set_Column() with a rotation of 90 or 270 degrees than to do
  41. * a Max7219_Set_Row(). The opposite is true for rotations of 0 or 180 degrees.
