Description

See the description of max7219.jal.


Notes

- This library is designed for max7219 modules controlling an 8x8 LED matrix,
         the features of the MAX7219 chips for 7-segment displays are disabled.
       - The terms 'row' and 'column' are ambiguous: depending on the orientation
         of the module! This library calls the LEDs which can be written with a
         single write operation a column. Writing a row of a single module requires
         8 writes and the cache being active.
         See the procedures max7219_display_col() and max7219_display_row().
