Código controlador MIDI

Para poder compilar el código debo en primer lugar indicar que utilizo las siguientes librerias:

MIDI: http://playground.arduino.cc/Main/MIDILibrary

U8glib: http://code.google.com/p/u8glib/

M2tklib: http://code.google.com/p/m2tklib/  ( no es imprescindible, pero si alguien se anima a modificar cosas, esta es sin duda una herramienta de gran ayuda )

El código lo hice en diferentes archivos, teneis el principal y a continuación los ".h" que componen el total del código. Podeis añadir con el IDE que viene por defecto en Arduino los archivos .h tal y como se indica aqui:

http://arduino.cc/es/Guide/Environment

To compile the code I must first state that I use the following libraries:

MIDI: http://playground.arduino.cc/Main/MIDILibrary

U8glib: http://code.google.com/p/u8glib/

M2tklib: http://code.google.com/p/m2tklib/ (not required, but if anyone is encouraged to change things, this is definitely a useful tool)

I did the code in different files, you have the main and then. "H" that make up the total code. . IDE you can add to the default one h files in Arduino as shown here:

Pido de antemano disculpas por cualquier error u omisión que afecte al código, si tenéis alguna duda respecto al código hacédmela saber.

Espero que disfrutéis con vuestro nuevo controlador MIDI.

I ask in advance apologies for any errors or omissions affecting the code, if you have any questions regarding hacédmela know code.

I hope you enjoy with your new MIDI Controller.

Material

Este es el listado de material de la última versión que tengo en marcha del controlador que sale en la foto.

Hubo una versión anterior con un display de 16×2 y otra versión posterior con un display de 16×4 caracteres, pero debido a que se me quedaba corto decidí implementar un display GLCD de 128X64 píxeles con la posibilidad de añadir gráficos.

A continuación describo los elementos que he utilizado en esta última (¿?) versión.

This is the list of material that I have latest version of the driver up in the photo.

There was an earlier version with a display of 16 × 2 and a later version with a display of 16 × 4 character, but because I fell short I decided to implement a 128X64 GLCD display pixels with the ability to add graphics.

Below I describe the items that I have used in the last (?) Version.


Núcleo / Core :

Arduino UNO y su IDE.

Medio para visualizar la información:

Pantalla 128X64 GLCD ( permite visualizar gráficos )

Means for displaying the information:

128X64 GLCD display (used to display graphics)

Control:

4 potenciómetros ( lineales no importa el valor), un encoder y un pulsador.

Control:

4 sliders (linear no matter the value), an encoder and a button.

Esquemático donde se puede apreciar los diferentes módulos MIDI IN, OUT y TRHU que lo conforman y sus componentes.

Schematic where you can see the different modules MIDI IN, OUT and THRU comprising it and its components.

Conectores DIN 5 hembra (hay muchos modelos, yo escogí el que NO era aéreo y podia soldarlo en la PCB).

5 female DIN connectors (there are many models, I chose the one that was NO air and I could solder on the PCB).

Opto-acoplador Sharp PC-900 o equivalente para el modulo MIDI IN.

Optocoupler Sharp PC-900 or equivalent to the MIDI IN module.

 

 

HCF4069UBE inversor hexadecimal para el modulo MIDI OUT.

HCF4069UBE hex inverter module to the MIDI OUT.

Resistencias de 220  y 280 Ohms y diodo 1N914, tal y como se indica en el esquemático.

Pcb con pistas y agujeros para trabajar con mas facilidad a la hora de soldar, evitando pegotes de estaño y por ende falsos contactos.

Resistors 220 and 280 Ohms and 1N914 diode, as indicated in the schematic.

Pcb with tracks and holes to work more easily when welding, avoiding globs of tin and therefore false contacts.

Cable rígido y las herramientas que corresponda.

Espadines, para poder hacer las conexiones

Como elemento final, elegí reunir todos estos elementos en una pieza de metacrilato por varios motivos:

• Elegante.

• Relativamente fácil de manipular.

Hard wire and tools appropriate.

Sprats, to make connections

As a final element, I chose to bring all these elements in a piece of acrylic for several reasons:

     Elegant.

     Relatively easy to manipulate.

Pero también caro si lo cortas con laser.

But also expensive if you cut with laser.

Edit
