* Support for multiple Max7219 units in a chain I'll move this support over to bugfix_2.0.0 in the next few days. And then look at updating the Max7219_idle() routine to make use of multiple units in a chain. * spelling correction

/**
|
|
* This module is off by default, but can be enabled to facilitate the display of
|
|
* extra debug information during code development.
|
|
*
|
|
* Just connect up 5V 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 MAX7219_CLK_PIN 77
|
|
* #define MAX7219_DIN_PIN 78
|
|
* #define MAX7219_LOAD_PIN 79
|
|
*
|
|
* Max7219_init() is called automatically at startup, and then there are a number of
|
|
* support functions available to control the LEDs in the 8x8 grid.
|
|
*
|
|
* If you are using the Max7219 matrix for firmware debug purposes in time sensitive
|
|
* areas of the code, please be aware that the orientation (rotation) of the display can
|
|
* affect the speed. The Max7219 can update a single column fairly fast. It is much
|
|
* faster to do a Max7219_Set_Column() with a rotation of 90 or 270 degrees than to do
|
|
* a Max7219_Set_Row(). The opposite is true for rotations of 0 or 180 degrees.
