Downloaded. Win 11 install on IDE 1.8.19 went properly.
<edit>: not even a system warning about file from download on execution.

T_4.1 BUILTIN_SDCARD ListFiles built and ran properly ... all 120,726 lines worth!

[defragster]

@Paul: just thought to read the end lines of CONSOLE from install and build p#2:

Multiple libraries were found for "SD.h"

Having installed the IDE 2.0 - even though running TDE 1.8.19 it is using the 1.56.1 tree tested 'back then'.

See this drive folder where unzipped 1.8.19 is installed - where TeensyDuino 1.57b1 has placed the new files:

Seems IDE 1.8.19 give preference to Hardware in the %appdata% folder.

[defragster]

To confirm the IDE was closed to remove>>: C:\Users\Tim\AppData\Local\Arduino15\packages\teen sy
> could not delete the folder because Teensy.exe and Teensy_ports were still active!
<edit>, BTW: killing those tasks allowed full delete to complete

So now the 1.57b1 install is in use and indeed Listfile.ino builds and runs:

Multiple libraries were found for "SD.h"

Morning All
See everyone was busy last night.

No problem on installing the the 1.57-beta1. As @defragster said this time no blue screens from Windows complaining about security.

Ran my updated MTP_Integrity Test sketch (has a few options to test multiple things with).

Breadcrumb: Saw this on startup do not know what the breadcrumbs mean so:

No Crash Data To Report
  Hopefully all is well, but certain types of crashes can't be reported:
	stuck in an infinite loop (technically, hardware still running properly)
	remaining in a low power sleep mode
	access to certain peripherals without their clock enabled (eg, FlexIO)
	change of CPU or bus clock speed without use of glitchless mux
  Breadcrumb #1 was 2705474578 (0xA1424412)
  Breadcrumb #2 was 4234545148 (0xFC6607FC)
  Breadcrumb #3 was 3439104072 (0xCCFC9048)
  Breadcrumb #4 was 170496750 (0xA2992EE)
  Breadcrumb #5 was 3875607432 (0xE7011388)

Tested Remove and replace on External SD Card using the Audio Shield:

### EXT1(0) removed dt:301000
... Not showing all the MTP debug stuff here....
### EXT1(0) inserted dt:1694000
*MTP_class::send_Event(400b)

then it showed up in the list on in windows explorer

USB/MTP:
As shown on the MSC thread it picks up the 2 external USB Drives:

Just as a followup I did update usb_desc to use MTP+SERIAL plus I had already uninstalled the package version in appdata for IDE2 at least for now - just makes it easier to update libraries and make changes. Besides not thrilled with IDE2 yet - there are still several outstanding PRs/Issues that need to be incorporated.

Guess maybe will test I2C slave since I never did that before.

[KurtE]

Paul - I had wondered if this beta would also show up as a new version for the Arduino boards packages...

i.e. if you had put the pieces in place to use the newer stuff in Arduino_cli that might better support headless...

I did confirm this morning the IDE 2 does not see new board updates. So I am assuming not. looks like I will need to remove it and/or simply continue
using the build I have, where I grab all of the pieces out of <sketches>/libraries/... and symbolic link into cores and ...

[KurtE]

Paul, I am also curious about having multiple Teensy installs using the Arduino15 stuff as mentioned versus how I have multiple Robotis OpenCM for example where one is in the Arduino15 and the others are in:
<sketches>/hardware/...

That is I tried building my Circuitpython test with new TD beta in 1.8.19 ran it from 1.8.19...

Using library USBHost_t36 at version 0.2 in folder: C:\Users\kurte\Documents\Arduino\libraries\USBHost_t36 
Using library SdFat at version 2.1.2 in folder: C:\Users\kurte\Documents\Arduino\libraries\SdFat 
Using library SPI at version 1.0 in folder: C:\Users\kurte\AppData\Local\Arduino15\packages\teensy\hardware\avr\1.56.1\libraries\SPI 
Using library MTP_Teensy at version 1.0.0 in folder: C:\Users\kurte\Documents\Arduino\libraries\MTP_Teensy 
Using library LittleFS at version 1.0.0 in folder: C:\Users\kurte\AppData\Local\Arduino15\packages\teensy\hardware\avr\1.56.1\libraries\LittleFS

Also in 1.8.19 I have a dev version of OpenCM (probably way out of date, but...), I also have the main boards package installed.

"C:\\Users\\kurte\\AppData\\Local\\Arduino15\\packages\\OpenCM904\\tools\\opencm_gcc\\5.4.0-2016q2/bin/arm-none-eabi-objcopy" -O binary "C:\\Users\\kurte\\AppData\\Local\\Temp\\arduino_build_180226/read_write_ax.ino.elf" "C:\\Users\\kurte\\AppData\\Local\\Temp\\arduino_build_180226/read_write_ax.ino.bin"

Sketch uses 46464 bytes (39%) of program storage space. Maximum is 116736 bytes.
Global variables use 8804 bytes of dynamic memory.

Maybe I will try a hack again back in (sketches)\Hardware to point to new teensy install...

[PaulStoffregen]

Paul - I had wondered if this beta would also show up as a new version for the Arduino boards packages...

Nope. I automated building the package zip files (though it's currently broken on MacOS), but updating the package index is still a very manual process. I didn't do it for this beta.

I'm not planning to put much work into the new packages until Arduino fixes issue #769. Yeah, people wanting headless support from Arduino CLI could benefit even if the GUI isn't properly supported. And if #769 doesn't get fixed, I'll do that after 1.57 is released, and maybe also 1 or 2 times as we get closer to 1.57 release. Maybe.

But I do believe we need a patch in the Java code to force use of the libraries from the Teensyduino installer and ignore any other Teensy packages. People can still use the packages with an unpatched copy of Arduino 1.8.19, and of course with Arduino 2.0 beta. But when using a copy of Arduino which has been modified by Teensyduino, the installer's files should always be used no matter what packages exist elsewhere. Not quite sure how to do that, but in a future where the packages are more easily findable, we need this in the 1.57 release.

[mjs513]

I2C Slave Mode - Seems to be working. Since I don't seem to do anything easy. I used the sketches from this post https://forum.pjrc.com/threads/69607...l=1#post300929 with the Master on a T4.1 and a T4 acting as a slave.

On slave I see:

sending (32 bytes)

and on the master I get:

Quick update: I un-installed the teensy IDE package.
So now building with new beta on 1.8.19


Note: I am still building with my fork of github of a few projects like SDFat, USBHost_t36... but are (or at least were ) in sync with the ones in beta.

Right now I am using the main branch of the MTP_Teensy project, which is pretty much in sync with what was my fast_start branch.

Note several of the examples that deal with MSC will not currently build as WIP to migrate the MSC support into USBHost and that is still a WIP.

(Note: I put back in the changes for MTP+Serial)

I have since then tried building and running a few sketches including:

(MTP_Teensy) Simple_mtp_ili9341_picture_view.ino which uses ILI9341_t3, does not use external libraries for some other bitmap formats.
(MTP_Teensy) CircutMicroPython.ino - experiments plugging in a CircuitPython or a MicroPython board to usbhost... Still playing with this one.

mtp_tft_picture_view (own project) - this is what the simple version was split off from. Actually we had this in the mtp_teensy, and then moved it out...
It does like the other one, but also optionally can use JPEGDec to decode jpeg files and PNGdec to handle PNG files, plus can do scalling, plus we have code in it to configure for several
different displays. ILI9341 (either ILI9341_t3 or ILI9341_t3n), ILI9488, ST7735 or ST7789, RA8875 or RA8876. Right now running on 7" RA8876

So far everything still appears to be working

[joepasquariello]

Paul, I have a question about calling yield() from the various "available" functions. These functions don't fit the pattern of calling yield() while waiting for something in hardware to finish, and I think therefore they should not call yield(). For example, for a UART, you might create a task that has a loop like in the first snippet below, where it waits by calling yield(). The second snippet below shows what it would have to look like to get the same behavior. I've looked at a number of Arduino cores and other systems with support for RTOS, and none of them call yield() or otherwise wait within available().

---------------------------------
if available() does NOT call yield()
-----------------------------------

  while (!available()) {
    yield();
  }
  read()
  etc.

---------------------------------
if available() calls yield()
-----------------------------------

  available();  // calls yield() internally, does not return until data is available
  read()
  etc.

[PaulStoffregen]

The behavior of Serial.available() is not changed to wait until data is available.

[joepasquariello]

The behavior of Serial.available() is not changed to wait until data is available.

Oh, sorry, now I see it's only in USB serial. Why did you decide to add it there, or was it already there?

Note that dynamic audio connection for the Teensy 3.x is available in PR#642

The last of these is fixed in my PR #642 (and duplicated in @KurtE’s #644).

Everything else is in AudioOutputPWM, which is @MarkT’s baby - see https://forum.pjrc.com/threads/69683...for-Teensy-4-1. I suspect the volatile attribute isn’t needed, it’s in no other audio object and all audio block manipulation is private to the library and done within the update interrupt. I think…

Installed ok on Mac Catalina 10.15.7
Haven't managed to crash the serial monitor (although this usually happens when the alzheimer's kicks in and I do something stupid)

Can't wait to throw some 'BreadCrumbs', any documentation I missed?

thanks

[PaulStoffregen]

Really glad to hear the MacOS crashing problem is gone.

[h4yn0nnym0u5e]

As noted on https://forum.pjrc.com/threads/70406...-cores-library, the dynamic AudioConnection has broken some previous code. That code did rely on bugs in the old AudioConnection and manually evading the restriction of “only one connection per input”, but I guess the backward incompatibility should at least be flagged.

[PaulStoffregen]

This line appears to be conflicting with the I2C onRecieve

AudioOutputI2S i2s2;

If i comment it out, the I2C works but if I put it in, it prevents the communication.

Committed a fix.

https://github.com/PaulStoffregen/Wi...6e53a27c9c66a8

I found I could also create the problem without the audio library, just using this:

  analogWriteFrequency(23, 12000000); // <-- also causes problem
  analogWrite(23, 128);

Turns out the having a nearby pin toggling at several MHz can couple to the I2C pins while the I2C peripheral is monitoring them to detect if the signals change. Turning on hysteresis solves it.
