#include <MIDI_Inputs/MCU/SevenSegmentDisplay.hpp>

Detailed Description

template<uint8_t LENGTH>
class MCU::SevenSegmentDisplay< LENGTH >

Class that receives and saves the text of a Mackie Control Universal 7-segment display like the assignment display and the time display.

Note
Implements Control Change updates only, not System Exclusive.
