Hi, I have a Project in mind:
a Midi device (USB) to add functionality to ANY connected USB-Midi-Controller/Switch.
more detail:
Footswitch (say 8 switches) – USB – Arduino – USB – Mac
this way you could for example have the arduino send different commands depending on how long you pressed that switch.
Problems:
Power to Arduino – Power through to USB Powered Footswitch
more than just one USB connector
What arduino devices would you recommend?
thanks in advance
Thomas
Almost any Arduino would work but not the minimal ones having very few I/O pins.
Can You show that in a drawing? Not clear what that would look like.
You'll need an Arduino (or external chip) that supports USB Host mode. Most Arduinos only support USB Drvice mode.
ok, Ill look that up.
possible device is ESP32-S3-DevKitC-1
The ESP32-S3 only has a single USB port, though.
A Teensy 4.1 has two.
It might help if you use your most trusted search engine first. You will find quite a number of projects.
the ESP32-S3-DevKitC-1 has two USB ports a USB-to-UART bridge and a full-speed USB OTG interface
okay, seems like i Already have a USB host supporting thingy.
Teensy 4.0... dumb me.
I'll dive deeper into this
Exactly, which is not what OP needs, because it's not connected to the ESP32S3 itself and it does not support MIDI over USB.
