Good luck! Hopefully it does lead to a good start.
I just came across that and figured sharing was easy enough to help your progress.
Easier to just start with the IDE ... of course I use the IDE and TD installs and build from editor with command line build - this works on Windows: github.com/Defragster/Tset
But this thread has...
The Parse code doesn't need changed as it just gets a string.
What would be different would be the file operations using SdFat to open and read the file to get those string from the file - so the...
OPPS - TYPO on my part See :: pjrc.com/threads/66357-Teensyduino-1-54-Beta-7
1.54 is in beta and the SdFat library and examples are in that release.
All of that code will work with SD.h - just...
What version of TeensyDuino is in use? If using the TD 1.54 Beta 7 the SD code actually uses installed SdFat. Though SdFat is included - but uses different functions and methods.
Not sure if...
Ick, that'll never do. Indeed that button needs to stay unpushed for normal operation to continue.
@sw_hunt: Is the current Beta TD 1.54 Beta 7 in use?
It has changed the SD code to defer to the SdFat code that seems to benchmark some 5 or more times faster on writes. Benchmark as seen showed...

Never looked at T_2++ card before - but between that and pjrc.com/teensy/td_libs_IRremote.html that is indeed a problem with single i2c pins and no indicated ability for Alternates?

I didn't check the numbers for the pt_#15 [glad I added that to that code :)] - but on deleting and find it saying 'delete partition' my guess was it created an extended part to hold the 4th...
Wiped the whole 128GB SD and added 4 new partitions of diff sizes than before - same result :(

No Joy. Went to old machine that doesn't fault on partitioning. Deleted #3 and #4 and recreated them. Same result:

Glad that helped, Teensy gets into setup less than 400ms after power on, and Host Computer never has USB is never connected by the time that happens because until Teensy startup.c finishes its work...

I took my quad partition SD to my old PC and it did not FAULT on plugging it in - then I removed the 4th Part that was ExFat with an odd partition number. I'll get that in a Teensy with updated libs...
Very odd it went from working to not working when the code looks right for the pins.
Not sure if there is maybe a disconnected or miswired pin? Or perhaps a bad pin - or solder bridge - on the...
RP2040.MM has a tracking number to me ... maybe next week? Hopefully by the time it arrives and unboxed the path to C/C++ building on Windows will be ready :)

Went for a MMod RP2040 with stuff in my SFun cart since I'll have to get carrier boards to see the Teensy4.MMod.
There was a note once about making an rPi breakout for Teensy to work with Pi Hats?...
So the 10 i2c devices are all Teensys? Are they on multiple i2c busses? They have unique addresses for their bus?
Typical pullup values noted for the 3.3V Teensy is 2.2K?
What does i2c SCANNER...
Not sure what sketch is Teensy main? But suspect it is possibly entering setup() and passing those first Serial.println("SETUP"); before the computer completes the connect to the Teensy?

Good the signal pins were found.
The digitalPinToInterrupt() isn't needed on Teensy, but yes, it needs to see every CHANGE not just RISING.
Better probably would be using the encoder library as...
This PJRC page might help? : pjrc.com/teensy/td_libs_Encoder.html
Amazon page doesn't show the pins by function among the 5 - hopefully it is marked or you found notes?
Yes, this is normal designed behavior of the Program Button.
That Button as Program Button - the bootloader chip halts the Teensy and prepares it for programming whenever it has power.
To wake...
Quick read suggest a FORM is a screen layout of some button images.

That is handy @brtaylor.

Bummer on the failed install but awesome it not only worked in the end - but with the improved write speed!

As noted in post#3 by Paul - it works here - using T_4.1 and a known good cable.

Hope was that the post #6 code would be a starting point to show the switches working. It is just a Bounce2 example modified as noted for two buttons.

@Paul - Another Ref point for above post USB-Serial-Print-Speed-Test and @mjs513 sketch.

Okay, was just clarifying the need to use Teensy Host to Emulate libusb as Windows Host would present it. T4.x makes sense.

Probably not :)
It seemed a new folder was needed - not sure if I can do that from the web?
If I had write permission - or you created a new git for that?

Some of that in MSC and USBHost work ongoing in other threads ( wwatson, WMXZ, KurtE, mjs513 ) - how many of those elements are supported now?

opps ... misread ... not an EE for solving the real problem then.

In use the direct read of the end switches may chatter as well - depending on how they are switched - could result in bouncing on/off - adding those as two more de bounced buttons may be better.
