There are two buffers for each direction for each uart, one in the physical hardware and a software buffer that is managed in the libraries.
The physical hardware buffers are 4 bytes long, as bytes are received they are automatically placed in...
Necro-posting, because I am so grateful!
I've been struggling with a mysterious data transfer issue that had to do with wrapping the Serial7 port in a MIDI object (Arduino MIDI library).
It turns out that the MIDI acquisition slowed things down...
I found this post in the forum and it's helpful, but not conclusive in my case.
I'm now mounting a "Teensy 4.1 Pins" to my daughterboard as pictured
I'd like to use pluggable sockets instead (to allow testing a daughterboard without soldering a...
On MacOS using Arduino IDE 2.2.x, the Teensyduino files are installed in a hidden "Library" folder in your home directory. On my Macbook Air using the lastest beta, the full pathname is...
I'm working in VS Code generally.
Where might I find the proper copies of
usb_desc.h and possibly usb_desc.c
to peruse?
(or within Arduino IDE for that matter)
So, my mission now is to explore getting Serial+MIDI+MTP(Very Beta) working for a serial port type.
I'd welcome collaborators on this... particularly those smarter than I.
Android File Transfer worked after a reboot!
This offers some real possibilities!
Thanks, all!
and using the Example_3_simple_SD.ino example from the MTP_Teensy library
@Davidelvig:
Based upon my experience with my TeensyMIDIPolySynth (which makes use of the T4.x + Teensy Audio Adapter), plugging an external device without a ground reference (battery-powered amplified speaker, etc.) into the headphone jack...
Both you and Google are my friend!
The first google hit for "MTP for Mac" is productive.
Searching "MTP for SWIFT" is less productive (more depressing?)
I did find this alleged solution at Android.com, though it and "CommanderOne" did not see...
Thanks, @AndyA
On further attempts, I noted that Arduino was not seeing a Serial port for terminal output. A reset of the selected Teensy allowed me to see this output from setup()
MTP_test

Is this possible?
I've tried the MTP examples after downloading from each of these :

I'm doing this on a Teensy 4.1 board... and not yet seeing a new USB connected drive on...
I am using the Teensy 3.2 with a VS1053 synth chip from VLSI.fi.
It has only a "headphone out" (no line out) and it has R, L and "GBUF" - and GBUF "should not be connected to other grounds" based on the VS1053 documentation.
I'm using the Teensy...
