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 Claudio

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:

}

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

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);

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
