* Initial conflict resolution All previous items resolved: - Use of ELAPSED() on timer code - Switch to use of defer_return_to_status=true as much as possible - Update & Clean Up of Max7219 routines * Resolve non-SD case in ultralcd.cpp

/**
|
|
* This module is off by default, but can be enabled to facilitate the display of
|
|
* extra debug information during code development. It assumes the existence of a
|
|
* Max7219 LED Matrix. A suitable device can be obtained 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, 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.
|
|
*
|
|
* void Max7219_init();
|
|
* void Max7219_PutByte(uint8_t data);
|
|
* void Max7219(uint8_t reg, uint8_t data);
|
|
* void Max7219_LED_Set(uint8_t row, uint8_t col, bool on);
|
|
* void Max7219_LED_On(uint8_t col, uint8_t row);
|
|
* void Max7219_LED_Off(uint8_t col, uint8_t row);
|
|
* void Max7219_LED_Toggle(uint8_t row, uint8_t col);
|
|
* void Max7219_Clear_Row(uint8_t row);
|
|
* void Max7219_Clear_Column(uint8_t col);
|
|
* void Max7219_Set_Row(uint8_t row, uint8_t val);
|
|
* void Max7219_Set_2_Rows(uint8_t row, uint16_t val);
|
|
* void Max7219_Set_4_Rows(uint8_t row, uint32_t val);
|
|
* void Max7219_Set_Column(uint8_t col, uint8_t val);
|
|
* void Max7219_idle_tasks();
