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...
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()
SDIO Storage 0 254 sdio 0 0
SD Storage 1 10 sd1...
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...
When I flash the board in the Arduino IDE, it sets the time to essentially now (?build time)
Not when flashing in PlatformIO
Here are the last lines of a verbose output after build and upload in PlatformIO
Do I need to adjust the...
I'm struggling to craft a search string for this, so please forgive if this has been answered.
For a new Teensy (4.1 in my case - and 3.2 until recently) that has not has an RTC connected or powered, I'll like to detect that the clock is not set...
I'm re-designing moving from Teensy 3.2 to Teensy 4.1
timeline.h defines a tmElements structure that has no "time zone" or "time zone offset" that I can see.
The solution depends on several things:
- discovering the time - from an external...
I'm listening but this is part of the discussion above my pay grade. Because of the current draw, I re-implemented an older circuit of mine for Push On - Hold Off, and am now using a separate RTC as noted earlier in this thread. I'd like to use...
