This all looks really cool! MTP is useful indeed, and I'm excited you're adding support. I'll certainly try it out and report back.
For my current project, MTP isn't ideal because it's being used...
I'm designing a project that records audio (WAV files) to the SD card on the audio shield, inside a waterproof enclosure.
I'm hoping to be able to connect to my laptop via USB, and see the files...
OK, I got this working! The solution was to switch to using the i2c_t3 library for the Teensy code. It appears that i2c slave mode with the better-known Wire.h is not supported on Teensy (?),...
And here's a simplified version of the code from the esp32 master, which just blinks the LEDs once per second and sends a 5-byte test message of 1, 2, 3, 4, 5 when the button is pressed.

To make things easier, here's a simpler version of what's running on the Teensy LC with the message-parsing and usbMIDI stuff stripped out. This still exhibits the same bug as above.

I'm prototyping a MIDI controller with an ESP32 board as the main MCU, but also using a Teensy LC for its easy usbMIDI capabilities. And there's an MCP23017 i2c i/o expander that's used to control a...
I'm building a little box to connect 2 piezo drum triggers (kick & snare), and convert them to USB-midi signals. I followed Paul's advice given in this forum thread for connecting one piezo trigger,...
I can't offer any detailed help with your setup, but in user interface lingo the term for the behavior you're looking for is "radio buttons": https://en.wikipedia.org/wiki/Radio_button
Gotcha. That sounds like it's over my head at this point.
I did read a bit about adding a flash chip. But I believe the maximum amount you can add is 16MB? I think I'd need a lot more for this...
Hello!
I found the Micro SD Card Adaptor in the store. My question is: could I connect several of these to a Teensy 4.1 and have simultaneous access to, say, 6 different SD cards?
This project...
Cool, I misunderstood something I read about analog output on 4.1. That makes more sense!
And thanks for the grounding advice. I hadn't thought of that.
Hello!
I'm using a Teensy 4.1 for an audio project. I'd like to use 8 LEDs as indicators, and be able to dim them on or off smoothly. I'm assuming I'll need some external chip to achieve this. Any...
Very helpful replies. Good to know the read speed in practice. Thanks!
Any idea if the write speeds would be similar?
Hello,
I'm looking to build an audio project that reads and writes audio to/from an SD card, and requires 8 analog inputs (pots to control volume etc) as well as audio I/O. As someone diving into...
