Serial Midi with custom BaudRate and Library version 5

[ClaudioCas]

Dear all,

I'm using the following code for initialize my Midi over Usb Serial with custom boudrate according with this doumentation (https://github.com/FortySevenEffects/arduino_midi_library/wiki/Using-custom-Settings) to use Arduino Mega and Hairless MIDI.

  #include <MIDI.h>
  struct CustomBaudRate : public midi::DefaultSettings{

      static const long BaudRate = 19200;

  };
  MIDI_CREATE_CUSTOM_INSTANCE(HardwareSerial, Serial, MIDI, CustomBaudRate);

It works great with versione 4.3.1.

I upgrade the library to version 5.0.2 for use native HID with Leonardo. The Usb Midi Native version works relly well, but now if I try to compile the old code (for Usb Serial) with new library I had the following errors:

I'm using Arduino IDE 2.0.0 beta 5

Thanks a lot

I cannot reproduce your error, your example code compiles fine on both Arduino IDE 1.8 and 2.0.

[ClaudioCas]

Dear Franky,
first of all, thanks a lot for your kind and quick reply.

This is a empty sketch and doesn't copile for me. I double check, I have 5.0.2 Midi Library

  #include <MIDI.h>

  //Arduno Mega + Hairless Midi = 19200;
  struct CustomBaudRate : public midi::DefaultSettings{

      static const long BaudRate = 19200;

  };
  MIDI_CREATE_CUSTOM_INSTANCE(HardwareSerial, Serial, MIDI, CustomBaudRate);


void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

[lathoub]

Leonardo uses Serial1, not Serial in the above example.
Change to:
MIDI_CREATE_CUSTOM_INSTANCE(HardwareSerial, Serial1, MIDI, CustomBaudRate);

See also:

arduino_midi_library/src/serialMIDI.h

Lines 105 to 109 in d9149d1

	#if defined(ARDUINO_SAM_DUE) || defined(USBCON) || defined(__MK20DX128__) || defined(__MK20DX256__) || defined(__MKL26Z64__)
	// Leonardo, Due and other USB boards use Serial1 by default.
	#define MIDI_CREATE_DEFAULT_INSTANCE() \
	MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI);
	#else

I have the same issue. Custom settings does not work at all. I tried the example above for Leonardo and still get the error:
MIDI_Library/src/serialMIDI.h:62:13: error: 'BaudRate' is not a member of 'midi::SerialMIDI<HardwareSerial, MySettings>::Settings {aka MySettings}' mSerial.begin(Settings::BaudRate); ^~~~~~~ exit status 1 Error compiling for board Arduino Leonardo.

MIDI Library ver.5.0.2
ESP core 2.0.14
target: ESP32S3 (LOLIN S3 Pro)
I can compile in Arduino IDE 1.8.20 , but cannot in Arduino IDE 2.3.1
target: ESP32S3 (LOLIN S3 Pro)
the errors start with

error: no matching function for call to 'midi::SerialMIDI<HardwareSerial, CustomBaudRateSettings>::SerialMIDI(HWCDC&)'
 MIDI_NAMESPACE::SerialMIDI<HardwareSerial, CustomBaudRateSettings> serialMIDI(Serial);

[lathoub]

When using the custom settings, make sure you use either a clone or copy from this repo, not a Release version (eg from the Arduino lib manager).

A new release is upcoming

Saw now while looking for a solution while compiling that acidbox project. Found a solution?
