Building a MIDI synth control

deepsky · December 22, 2023, 1:00pm

Hi! How are you guys? My name is Daniel Nobre, and Im follow the YouTube (DIIY MiniMoog) https://www.youtube.com/watch?v=PATlf0W3m7k - Ryan Boggs - so I download his Arduino Firmware sketch: MiniControl_v1.1 - Google Drive

and the MIDI Library 5.0.2

, installed the sketch and the MIDI Library at Arduino IDE....

Then I tried to verify the program and I receive a lot of errors...if someone could please load this sketch, install the library and then verify whats happening, Id be always grateful ! It will be my Xmas gift!!

Thanks!

Daniel...

Hello deepsky

Welcome to the world's best Arduino forum ever.

Post your sketch, well formated, with well-tempered comments in so called code tags and schematic to see how we can help.

Have a nice day and enjoy coding in C++.

How are you Paul? My goal here isnt coding, but just make the MIDI controller work... lol

If you could please download the Arduino Firmware sketch for MIDI : MiniControl_v1.1 - Google Drive

and the MIDI Library 5.0.2 (MIDI Library - Arduino Reference)

, installed the sketch and the MIDI Library at Arduino IDE....

and then if you could run this program without errors...it will really be amazing! Anything you could do!

The MCP492X.h and MCP41HVX1.h are also needed for running the sketch......its available at:

github.com

michd/Arduino-MCP492X/blob/master/MCP492X.h

/*
 * MCP4921/MCP4922 12 bit DAC Library
 * By MichD
 *
 * GitHub: https://github.com/michd/Arduino-MCP492X
 *
 * The Microchip MCP4921 and MCP4922 are 12 bit digital to analog converters
 * with an SPI interface. The MCP4921 has one DAC output, the MCP4922 has two.
 *
 * This library is built around the Arduino default SPI library and uses the
 * designated SPI pins, in addition to a configurable chip select pin, passed
 * in the constructor.
 * Look up the designated pins for your arduino board, and wire up as follows:
 *
 * | Arduino | MCP492X   | MCP4921 pin | MCP4922 pin |
 * |---------|-----------|-------------|-------------|
 * | SCK     | SCK       | 3           | 4           |
 * | MOSI    | SDI       | 4           | 5           |
 * | your CS | CS        | 2           | 3           |

@deepsky
Did you install the MCP492X and MCP41HVX1 libraries?

PerryBebbington · December 23, 2023, 2:38pm

@deepsky ,

I've deleted your reply #5 because it is inappropriate with regard to the purpose of this forum. Please keep the discussion on track for what you are asking for help for, and the general nature of this forum, which is help with Arduino based projects.

Thank you

Edit
@StefanL38
I've deleted your reply too.

Please keep on track, otherwise don't reply.

Thank you

no you need to

install the complete libraries not only *.h-files

I did so and it compiles just fine.
This means your installation is missing files.
So you should either install it new
or check what files are missing
