Programming 4.1 breakout with Visual Studio / PlatformIO possible, error message....

[Keeze]

Hi Andrei,

I try to create a project in Visual Studio with platformIO. Created a new preject and pasted alterd code for my need.

Problem is that I get the followong message. By the way, code compiles (not tested yet on the Teensy).

no instance of overloaded function "midi::MidiInterface<Transport, _Settings, _Platform>::send [with Transport=midi::SerialMIDI<HardwareSerial, midi::DefaultSerialSettings>, _Settings=midi::DefaultSettings, _Platform=midi::DefaultPlatform]" matches the argument list -- argument types are: (byte, byte, byte, byte) -- object type is: midi::MidiInterface<midi::SerialMIDI<HardwareSerial, midi::DefaultSerialSettings>, midi::DefaultSettings, midi::DefaultPlatform>

Do you have experience with coding in Visual Studio Code and can you see whats wrong?

Code:

/* Create a "class compliant " USB to 8 MIDI IN and 8 MIDI OUT interface.

   MIDI receive (6N138 optocoupler) input circuit and series resistor
   outputs need to be connected to Serial1, Serial2 and Serial3.

   You must select MIDIx4 from the "Tools > USB Type" menu

   This example code is in the public domain.

Sorry, I'm not using Visual Studio. But for 8x8 interface you must select MIDIx16 in the configuration. The comment is left over from 3x3 sample code. Let me fix it.
