/* USB MIDI Sync Slave Box Monitor
|
|
||||||
*
|
|
||||||
* This example demonstrates how to create a |
|
||||||
* MIDI slave clock box with
|
|
||||||
* monitor support using oled display |
|
||||||
*
|
|
||||||
* MIDI in must be provided via an opto-isolator to pin RX/D0
|
|
||||||
* on an Arduino Uno. |
|
||||||
* |
|
||||||
* You need the following libraries to make it work |
|
||||||
* - Midi Library |
|
||||||
* - u8g2 |
|
||||||
* - uClock |
|
||||||
* This example code is in the public domain. |
|
||||||
* |

||||||
* Code by midilab contact@midilab.co |

||||||
* Example modified by Jackson Devices contact@jacksondevices.com |
