ESP32-S3 + Adafruit TinyUSB Arduino

[morphee909]

Hi,

I'm planning the design of a midi controller based on ESP32-S3 and Arduino core. I need MIDI over USB so I have to use this library

http://github.com/adafruit/Adafruit_TinyUSB_Arduino

I did not find anything else compatible with esp32 for usb midi transport.

The problem is, if I want to upload a sketch I have 2 options :

1 : I add a push button on boot0. But the MCU and the push button will be under an enclosure, I don't want to open the enclosure just to upload a sketch.

2 : I could use a usb to uart converter IC like CP2101 but now I lose the direct usb connection between mcu and computer to transfer midi ,there is the converter IC across the way, and I don't think the TinyUSB library can work that way.

What can I do ?

You can use two USB ports like the DevKitC does.
Or observe the ESP in its natural WiFi/Bluetooth habitat and use OTA to wirelessly upload new firmware
