I was pleased to discover that Croatia has a contender in the Arduino world. We will certainly find applications for Croduino in our laboratory projects, and I’m eager to start exploring it. I’m personally involved in music, and I’m very interested in Croduino’s capabilities for MIDI communication. My question is whether it’s possible to achieve MIDI communication over USB with Croduino (I’m confident classic MIDI will work), for example by loading libraries such as https://www.arduino.cc/en/Reference/MIDIUSB or something similar?

Evo jako sam se iznenadio kad sam vidio da Hrvatska ima konja za utrku u
Arduino svijetu. Svakako kod nekih naših aplikacija u laboratoriju ćemo
naći primjenu i jedva čekam da krenem s istraživanjem. U privatnom planu
se bavim glazbom pa bi mi od velike koristi bile mogućnosti Croduina u
MIDI komunikaciji. Moje pitanje je da li je moguće sa Croduinom
ostvariti MIDI komunikaciju preko USB-a (klasični MIDI sam uvjeren da
može ići) npr. ako bi se učitale biblioteke kao npr. ova
https://www.arduino.cc/en/Reference/MIDIUSB ili nekakva druga…

You can use that specific library with Croduino, as well as most others, since Croduino Basic is powered by Atmega328. For reference on how MIDI libraries are used, see these projects from colleagues: project:synthomir [Radiona Wiki] and https://www.facebook.com/velvetfestival/

hvala Vam na interesu za Croduino.
Možete koristiti konkretnu biblioteku s Croduinom, kao i većinu ostalih s obzirom da Croduino Basic pogoni Atmega328.

Thank you for the quick response! I was confused by the controller name—I see Atmega328 listed for Croduino, but all the specifications mention Atmega32u4. I’ll be in touch once I’ve assembled everything.

Tiho, Hvala puno na brzom odgovoru! Bunio me naziv kontrolera (kod vas Atmega328 a u svim specifikacijama Atmega 32u4) Kad složim stvar javljam se hehe [name removed], dipl.ing.el.

Soldered Support:
The difference is that the 32u4 has a built-in USB transceiver. On Croduino Basic(1), we use an FTDI chip for that function, and on Croduino Basic(2) we use a CP2102 USB to UART bridge.
Original message (Croatian)
razlika je što 32u4 ima ugrađen USB transceiver. Na Croduinu Basic(1), za tu funkciju, koristimo FTDI a na Croduino Basic(2) pločici CP2102 USB to UART bridge.
Veselimo se suradnji.
Customer:
I’m back with another question. I’ve worked through the USB MIDI issue, but after further research I see that my device would need to control Croduino over USB, which means Croduino would need to be a USB Host, not a Device. Do you offer a USB host module in your product line, or is there a software trick to convert Croduino to Host mode?
Original message (Croatian)
Evo mene opet, ali ne bez razloga… Super da smo riješili dilemu oko USB MIDI-ja, no po proučavanju stvari vidim da bi mogao spojiti svoj uređaj koji bi kontrolirao preko USB-a, Croduino bi trebao biti u stvari USB Host, a ne Device. Da li nudite u svom programu i USB host modul ili se na neki softverski trik Croduino može preraditi u Host? Hvala još jednom! [name removed], dipl.ing.el.

Soldered Support:
Yes, exactly—you need a Host! We previously offered an Arduino USB host shield, but unfortunately we no longer stock it: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics Unfortunately, with the hardware on Basic/Basic2 you cannot have USB host. You would need a microcontroller that implements USB internally to have that capability, such as Arduino Due: https://www.arduino.cc/en/Reference/USBHost
Original message (Croatian)
da, upravo tako, trebate Host! Prije smo nudili Arduino USB host shield, ali ga nažalost više ne držimo

Nažalost s hardwareom na Basicu/Basicu2 ne možete imati USB host. Trebali biste neki mikrokontroler koji implementira USB u sebi kako biste bili u toj mogućnosti, npr. Arduino Due: https://www.arduino.cc/en/Reference/USBHost
