LCD< BufferSize > Class Template Reference

#include <MIDI_Inputs/MCU/LCD.hpp>

Detailed Description

template<uint8_t BufferSize = 112>
class MCU::LCD< BufferSize >

A class that represents the Mackie Control Universal LCD display and saves the text it receives.

The format of the MIDI message is as follows (hex):

SysEx Start	Data 1	Data 2	Data 3	Data 4	Data 5	Data 6	Data 7	...	SysEx End
F0	mm	mm	mm	nn	12	oo	yy	...	F7

• mm is manufacturer ID (00 00 66 for Mackie)
• nn is model number (10 for Logic Control, 11 for Logic Control XT)
• oo is offset relative to the first character of the LCD [0x00, 0x6F]
• yy... is the ASCII text data

The manufacturer ID and model number are ignored by this class.

Examples

MCU-OLED-SSD1306-x2.ino.

Constructor & Destructor Documentation

LCD()

template<uint8_t BufferSize = 112>

LCD ( uint8_t offset = 0, Cable cable = Cable_1 )

inline

Parameters

offset	The text sent over MIDI is 112 characters long, by changing the offset within this text and the length of the text, we can listen to just a section of the text. E.g. offset = 56 and BufferSize = 56 will listen to just the second line of the LCD display. The default is offset = 0 and BufferSize = 112, i.e. listening to the entire display.
cable	The MIDI USB cable number to listen for.
