* I - Initialize (clear) the matrix
* F - Fill the matrix (set all bits)
* P - Dump the led_line[] array values
* C<column> - Set a column to the 8-bit value V
* R<row> - Set a row to the 8-bit value V
* X<pos> - X position of an LED to set or toggle
* Y<pos> - Y position of an LED to set or toggle
* V<value> - The potentially 32-bit value or on/off state to set
* (for example: a chain of 4 Max7219 devices can have 32 bit
* rows or columns depending upon rotation)
* C<column> - Set a column to the bitmask given by 'V' (Units 0-3 in portrait layout)
* R<row> - Set a row to the bitmask given by 'V' (Units 0-3 in landscape layout)
* X<pos> - X index of an LED to set or toggle
* Y<pos> - Y index of an LED to set or toggle
* V<value> - LED on/off state or row/column bitmask (8, 16, 24, or 32-bits)
* ('C' / 'R' can be used to update up to 4 units at once)
*
* Directly set a native matrix row to the 8-bit value 'V':
* D<line> - Display line (0..7)
* U<unit> - Unit index (0..MAX7219_NUMBER_UNITS-1)
