/**
|
|
* This module is normally not enabled and does not generate any code. But it
|
|
* can be enabled to facilitate the display of extra debug information during
|
|
* code development. It assumes the existance of a Max7219 LED Matrix. You
|
|
* can get one on eBay similar to this: http://www.ebay.com/itm/191781645249
|
|
* for under $2.00 including shipping.
|
|
*
|
|
* Just connect up +5v 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
|
|
*
|
|
* You first call Max7219_init() and then you have 3 support functions available
|
|
* to control the LED's in the 8x8 grid.
|
|
*
|
|
* void Max7219_init();
|
|
* void Max7219_PutByte(uint8_t data);
|
|
* void Max7219(uint8_t reg, uint8_t data);
|
|
* void Max7219_LED_On( int8_t row, int8_t col);
|
|
* void Max7219_LED_Off( int8_t row, int8_t col);
|
|
* void Max7219_LED_Toggle( int8_t row, int8_t col);
|
|
* void Max7219_Clear_Row( int8_t row);
|
|
* void Max7219_Clear_Column( int8_t col);
|
|
* void Max7219_Set_Row( int8_t row, int8_t val);
|
|
* void Max7219_Set_Column( int8_t column, int8_t val);
|
