MIDI Library without Arduino.h

[zerbian]

Hello there,
I am currently trying to write code without using the Arduino.h implmented feature, but I still want to use the MIDI Library in my program. Maybe someone can point me to the right resources for setting the UART / Serial register. I am currently writing for a ATMega328p, any help is welcome!
Thanks

The MIDI library can be used on AVR processors without the Arduino core.

I have some examples using a hardware abstraction layer based on C++ templates (FortySevenEffects/cake) at FortySevenEffects/monosynth. It might need a little digging to see how it works.

The general idea is to use a custom transport for the MIDI Library, that maps to your RX/TX buffers, themselves being connected to the UART via interrupt handlers.

That was fast! Thank you!
I will try to familiarize myself with the code and inner workings, but I am more accustomed to C (which is very hands on with the chip datasheet) and not C++

You can also look at the default Serial transport, it shows the API contract expected by the library. If you duplicate the class and implement its methods by connecting them to the UART, you'll be able to use that as a transport for the library:

MyCustomTransport transport;
midi::MidiInterface<MyCustomTransport> MIDI(transport);

Note: because your custom transport is likely not to use SerialSettings, remember to start your UART at the MIDI baud rate of 31250.
