#include <MIDI_Inputs/LEDs/MCU/VULEDs.hpp>

Detailed Description

template<uint8_t NumLEDs>
class MCU::VULEDs< NumLEDs >

A MIDI input element that represents a Mackie Control Universal VU meter and displays its value using LEDs.

Template Parameters

NumLEDs The number of LEDs for the VU meter display. Recommended value is 12, because this is the range that's sent over MIDI.

Examples: 4.VULEDs.ino.

◆ VULEDs() [1/2]

template<uint8_t NumLEDs>

VULEDs	(	const PinList< NumLEDs > &	leds,
		uint8_t	track,
		MIDIChannelCable	channelCN,
		unsigned int	decayTime = VUDecay::Default )

inline

Parameters

leds	The pins with the LEDs connected.
track	The track of the VU meter. [1, 8]
channelCN	The MIDI channel [Channel_1, Channel_16] and Cable Number [Cable_1, Cable_16].
decayTime	The time in milliseconds it takes for the value to decay one step. The MCU protocol uses 300 ms per division, and two steps per division, so the default is 150 ms per step. Some software doesn't work if the VU meter decays automatically, in that case, you can set the decay time to zero to disable the decay.
