ESP32 S2 and S3 support??

[jhsa]

Would it be possible to make this library work with the ESP32 S2 and S3? Both support native USB.
Thanks

I don't have the hardware, it crossed my mind, but hoping other would contribute - you? (What underlying lib from S2 or S3 can we use?)

[jhsa]

I believe this one can do it as well. But I do prefer the way you library handles the MIDI, based on the arduino midi library which is quite intuitive for a beginner like me. About the hardware, are you in Europe?

I’ll have a look at the Tiny-USB API
(Yes, Europe based (Belgium))

Cool, I am in Germany. Is there a way we can send Private messages here?

The ESP32 S2 can do WiFi and native USB but it cannot do BLE Midi unfortunately.
The ESP32 S3 should be able to do all of them. This board seems to be quite new and it is still a bit expensive. I am still waiting for it. I do have a couple ESP32 S2 Mino though.

Is there anything new known about USB MIDI on the ESP32-S3?

I want to build a MIDI instrument that can switch between BLE MIDI and USB MIDI. I am hoping the S3 can do this.

I did found this and looks promising (albeit USB only), but i never tried - can you try?

[DonWT]

I don't have an S3 right now but I will order one and give it a try.

I am successfully using Serial, USB, BLE, and RTP Midi on an S3. All in the same project.
For the USB I am using the library I have linked above. "TinyUSB"
I do love the ESP32-S3 board by the way. Very versatile.

Cool! Can you post the code on how to use TinyUSB with this lib?

Well, I believe I use the "TinyUSB" library instead of this one, not "with" this one.
Also, I think I am using the "TinyUSB" library because I couldn't make this one work at the time. Don't know if anything changed lately. But I can post how I use it. The following is just an example:

#include <Adafruit_TinyUSB.h>
#include <MIDI.h>

// USB MIDI object
Adafruit_USBD_MIDI usb_midi;

// Create a new instance of the Arduino MIDI Library,
// and attach usb_midi as the transport.
MIDI_CREATE_INSTANCE(Adafruit_USBD_MIDI, usb_midi, MidiUsb);

// Create a new instance of the Arduino MIDI Library for serial
MIDI_CREATE_INSTANCE(HardwareSerial, Serial, DIN_MIDI);

void setup() {
//************ USB MIDI init ***************
  TinyUSBDevice.setManufacturerDescriptor("My_Manufacturer");
  TinyUSBDevice.setProductDescriptor("iL9_USB");


  MidiUsb.begin(MIDI_CHANNEL_OMNI);

  MidiUsb.setHandleProgramChange(USB_ProgramChange);
  MidiUsb.setHandleControlChange(USB_ControlChange);
}

void USB_ProgramChange(byte channel, byte program) {
// Do whatever needs to be done when receiving Program Change.
}

void USB_ControlChange(byte channel, byte controller, byte value)
{
// Do whatever needs to be done when receiving Control Change.
}

void loop() {

MidiUsb.read();

}

And to send MIDI via USB:

MidiUsb.sendControlChange(Control, Value, Channel);  // To send Control change messages

MidiUsb.sendProgramChange(Program , Channel);    // To send Program change messages

The picture shows the Boards configuration I use to make it work.

Looks like TinyUSB exposes a serial interface (rather than a USB device). Good to know
Thx for the research

Would you please tell me which board you are using.

ESP32-S3 N16R8
It has two USB type C connectors.
