This message was updated from the old details about the first CLI Alpha release to more current versions of both the
CLI as well as the "RC candidates for the Arduino IDE2.

Most of this was taken from a few of Paul's posts.

Arduino IDE 2

You can download the: Future Version of the Arduino IDE from the Arduino Software Page
I started with the RC7 page. I personally will continue to monitor the Github IDE changes and will use daily builds again once there are additional changes.

Many of the earlier rough edges of the earlier builds have improved with RC7. Not saying it is perfect yet, but a lot better! I have started using it again to do some of the Arduino testing. Again this is the first build that supports SEREMU.


Paul has built a "Real" setup to plug into the Arduino Board Manager, currently it is based on TD 1.56

Once you have the IDE 2 up and running, you open open up the Preferences Page: On Windows File->Preferences
You will see a dialog that looks like:

As you can see in the Additional board manager URLS you enter:
Code:
https://www.pjrc.com/teensy/td_156/package_teensy_index.json

Close the dialog.. I found I needed to exit the IDE and restart it and then you can now install the Teensy boards.
You Open the Boards Manager and Scroll down until you see the Teensy Install and click the Install button.

You then should have the Teensy boards installed. Note: this install stuff in a different location then the Teensyduino installs.
On my Windows machine it is stored at: C:\Users\kurte\AppData\Local\Arduino15\packages\teensy

And if you find any issues with the Arduino IDE, you might want to search the list of issues that have already been open.
You can find them up at: https://github.com/arduino/arduino-ide/issues

Some notes: on issues and things you might run into.

1) If you install the install IDE2 and the Teensy board. When you try to use Arduino builds like 1.8.19 and for example install TD 1.57B2, by default Arduino will see your install for teensy from the board manager (arduino15) and use it. Paul has posted a patch to the Arduino install for it to instead use the one installed within the Arduino install: more details and zip file up at: https://forum.pjrc.com/threads/5354...Teensy-Support?p=307482&viewfull=1#post307482

2) On the first install of the IDE2, installs a set of default libraries into your <Sketches folder>/libraries/ Including an SD library. With our current install this one will take priority over the one installed by Teensyduino. I have potential fix for this, mentioned in the post #202. And that is to update the library.properties file in TD version of
SD library to change the: architectures=*
to: architectures=avr,*
More information on Search order can be found at: https://arduino.github.io/arduino-cli/dev/sketch-build-process/#dependency-resolution

Edit: Arduino is now looking at adding another directory to store the Arduino level libraries, like it has been done in Arduino 1.x:
https://github.com/arduino/arduino-ide/issues/1055


3) When I installed RC7 (actually the nightly before it), when it ran on my main machine, it wiped out my list of installed boards. The board manager showed there were
no boards...
This is issue: https://github.com/arduino/arduino-ide/issues/1036
Had do do with with the install of certain releases of ESP8236. Also replicates if you type in a URL in the extras boards which does not exist.
There is a pending Pull Request to hopefully fix this. I resolved it by deleting (rename) my arduino15 directory and started from scratch.

4) If you edit boards.txt or local.boards.txt, the system may not see these changes. I ran into this, by copying over the 1.57B2 stuff, which had the new Serial + MTP
But also could reproduce, by editing boards.txt and say I want to enable faster speed on T3.2.
Issue: https://github.com/arduino/arduino-ide/issues/1030 also https://github.com/arduino/arduino-ide/issues/591
As per @per1234 (github) PerT? work around:

Code:
    Select File > Quit from the Arduino IDE menus if it is running.
    Delete the "User data" folder:
        Windows:  C:\Users\<user name>\AppData\Roaming\arduino-ide\
        Linux:  ~/.config/arduino-ide/
        macOS: ~/Library/Application Support/arduino-ide/

    Start the Arduino IDE.

5) Suggestion by @PerT in post #204, that the Teensy Board URL at some point be a static URL that covers all of the releases of it and does not contain
the actual release number: That is instead of: https://www.pjrc.com/teensy/td_156/package_teensy_index.json
hopefully there will be something like: https://www.pjrc.com/teensy/package_teensy_index.json

6) Stability issues with Language Server. This is the code that when you hover over something, it will show you something like:
screenshot.jpg
Makes me want to go in and edit some of our header files and add more details.
Issues include: https://github.com/arduino/arduino-ide/issues/1042

Edit (6/17): 7) There appears to be issue with at least the daily build, should check on RC7 as well. But Serial.available and the like does not appear to return data if Teeny port is selected, until something in your code does an output to Serial... i.e. Serial.print(...)
https://github.com/arduino/arduino-ide/issues/1072

Edit: (7/6): This appears to be a Windows only issue and the problem appears to be in teensy-monitor code as can replicate without any Arduino IDE/CLI code.

More recent notes of trying out arduino-cli with teensy support on both Windows and Raspberry PI running ubuntu 64 bits.

Installing it - Is it already installed as part of the IDE?
Yes: It is in the resources/app/node_modules/arduino-ide-extension/build subfolder of the Arduino IDE installation folder.
So my nightly build it is installed at: C:\arduino-ide_nightly\resources\app\node_modules\arduino-ide-extension\build
and released version: C:\Program Files\Arduino IDE\resources\app\node_modules\arduino-ide-extension\build

But: before I knew this, I installed from: [arduino/arduino-cli: Arduino command line tool (github.com)](https://github.com/arduino/arduino-cli) Clicked on the latest release on the right-hand side of screen. And made sure add the location to the Path.

Compiling
Doing the command: arduino-cli --help
Gives you a clue to use the compile: compile Compiles Arduino sketches.

Likewise, the help on that command helps some:

Code:
C:\Users\kurte>arduino-cli compile --help
Compiles Arduino sketches.

Usage:
  arduino-cli compile [flags]

Examples:
  arduino-cli compile -b arduino:avr:uno /home/user/Arduino/MySketch

  -v, --verbose                   Print the logs on the standard output.

So what is the FQBN (yet another TLA ;) actually FLA) for a Teensy?
One way to get an idea is to use the command:
Code:
C:\Users\kurte>arduino-cli board list
Port               Protocol Type         Board Name FQBN                Core
usb:0/140000/0/8/4 teensy   Teensy Ports Teensy 4.0 teensy:avr:teensy40 teensy:avr

So found out both the FQBN and the port name, in this case it was T40 compiled with a USB type that does not include USB Serial. Another run with a Teensy MicroMod
Code:
C:\Users\kurte>arduino-cli board list
Port                 Protocol Type              Board Name      FQBN                Core
COM27                serial   Serial Port (USB) Unknown
usb:0/140000/0/8/1/1 teensy   Teensy Ports      Teensy MicroMod teensy:avr:teensyMM teensy:avr
Now how to do I compile a sketch: first attempt (actually probably 10th) :

Note: one of my first attempts failed to find any of the libraries. Turns out the CLI does not look into the same configuration stuff as either IDE... And it was defaulting to default location which is under the onedrive... on my W11 machine. My sketchbook is not there. So fiddled around with it for a while and found:
Code:
arduino-cli config init

Then edited the file mentioned and set the correct location.

But now that is working, In this case I changed directory to the location of sketch
Code:
D:\github\mtp_tft_picture_view>arduino-cli compile -b teensy:avr:teensyMM

How do I define Build Options?
That is how do I Build with using not the default options? The CLI help gave a couple examples of using a larger hammer to replace major settings, but nothing appears to apply (at least to me)

Updated: the FQBN in this case is far more than just information about the board, it also allows you to specify all of the values for the menu items as part of it.

So the short answer on how to build with USB set to MTP Serial is:
Code:
D:\github\mtp_tft_picture_view>arduino-cli compile -b teensy:avr:teensyMM:usb=serialmtp
D:\github\mtp_tft_picture_view\mtp_tft_picture_view.ino:147:17: note: '#pragma message: Display: ILI9341_t3n'

Which is a lot cleaner than my previous fumbling around solution I tried before this:
Code:
D:\github\mtp_tft_picture_view>arduino-cli compile -b teensy:avr:teensyMM --build-property="build.usbtype=USB_MTPDISK_SERIAL" --clean
Which worked, but I had to manually add --clean as the command did not know directly I changed settings and so the core files were not rebuilt.
Also - was considered a major hack that may or may not work i the future.

:D

But how do you find out about what are the valid FQBN options? That is where the command:

C:\Users\kurte>arduino-cli upload -p usb:0/140000/0/8/1/1 D:\github\mtp_tft_picture_view

Headless uploads, for example to Raspberry PI over SSH. I am ussing KiTTy (derived from PuTTy)
If you actually running on the RPI using a monitor, keyboard, mouse, you can use all of the same as above.

Currently when building for Teensy boards, headless uploads are not fully supported yet. That is the upload will try to launch the GUI teensy app.

So currently I am using teensly_loader_cli, or may also try TyTools.

To make it easier I thought I would use the --export-binaries
Code:

As you can see it saves the output files into sub-directory build and subdirectory based off of the main FQBN string.

So was able to program it using the command:
Code:
kurte@kurte-rpi4:~/github/mtp_tft_picture_view$ teensy_loader_cli --mcu=TEENSY_MICROMOD -w build/teensy.avr.teensyMM/mtp_tft_picture_view.ino.hex
kurte@kurte-rpi4:~/github/mtp_tft_picture_view$

Note: In this case I pressed the program button.

And I was also able to program the teensy using the tytools which I downloaded sources from: https://github.com/Koromix/tytools
And built them on the RPI using the instructions given in the Readme file
Code:
Supported firmware formats: elf, ihex.
kurte@kurte-rpi4:~$ tycmd upload ~/github/mtp_tft_picture_view/build/teensy.avr.teensyMM/mtp_tft_picture_view.ino.hex

Hopefully this version of the information is a little easier to understand!

Id love to abandon the Arduino IDE and move to visual code which is a far superior editor, if work is required to help teensy get enabled Ill tentatively put my hand up.

having just tried it out - it appears to require the new http://package.json support instead of the manual installation into the hardware folder.

all my other boards that have that packaging layer are just working as - is but the teensy and other manual ones dont show.

@rjp: In the IDE 'file / Preferences' you can select 'Use external editor' that opens the file 'Read Only' to Build and upload using the provided toolchain - the IDE uses the externally saved disk copy to build - that is if using a preferred external editor.

If using Visual Studio [for 'visual code' ?] there is a 'Visual Micro' plug in for that is used by some and generally seems to be kept working for Teensy. I just installed VS but haven't bothered trying VMicro yet as I'm doing okay with IDE and SublimeText for the editor.
 
thanks @defragster but alas ive tried all that.


Visual Micro is for the big fat version of visual studio, not the new lean mean visual code.

it was also quite clumsy from memory, i didnt want to persist with it or visual studio.


the arduino ide is just terrible to me - i dislike the menu behaviour and the awkward hovering games, i dislike the startup time, the actual builtin editor is the least of the problems :)

visual code is like vim, super fast to start, dumps you into a folder of your code to edit as you please, command shell to trigger tools and actions.

Ill raise my voice as someone who would love a command line only version of teensy and ill do my best to help make it happen if required.
 
Went looking for 'visual code' - is that the subset of MSFT Visual Studio app?

Will it work as external editor?

I share the finding of terrible 'awkward hovering games' in the IDE - the Menu usage is very non-standard Windows behavior from keyboard and the twitchy mouse jumping on undesired menu items on a whim is painful.

IDE startup was just now 9 seconds on closing and opening with it and reopening 11 sketches? I have all that running from a secondary SSD drive. It does take some time to scan any library and hardware chain it seems - but not as bad now as it has been, then I just leave it open - which is why I have 11 open sketches.

I generally suffer with the IDE for editing but use TyCommander for the loader and SerMon portions which takes out some of the pain of the IDE. Using the external editor is not as handy for navigating recent and creating new projects with the directory name of the sketch name.

I tried Visual Micro when I had VS2015 and it was a bit green then - not anxious to wade back in again as what I have it working.
 
https://code.visualstudio.com/

its super fast on startup and it works off a completely agnostic "open folder" paradigm which defies project file madness.

an open source effort from microsoft that runs seperately to visual studio, the linux version is identical to the windows one which makes my platform jumping realities much easier to deal with.

ctrl ~ toggles a terminal shelll with history so you can fire off tools and builds, microsoft accidently created a winner.
 
That is what I found VisualStudio Code - they have an Arduino Extension - but not Visual Micro so it may not fit the Teensy install/extend model the way VisualMicro has done.

It requires the non-windows IDE - just like Teensy - but I don't know if it is ready to set up and run with the Teensy layout of tools and building, have you tried that?
 
:) ill give it a go.

ideally, the command line tool would replace the need for the whole dance with that Java IDE and its unfortunate ui.

im not ready to give up on the dream just yet!

nope this one also only detects the boards in the package manager system and ignores the ones manually installed in /hardware

i wonder how much work it is to make a layer for teensyduino that obeys that package.json system.

this would appear to fix both the arduino-cli and the visual code plugin.
 
I'm using VisualStudio without VisualMicro. I'm building and uploading using the makefile support of the IDE. This is surprisingly easy, sketches compile very fast and intellisense works nicely. I'm sure you can do the same in Visual Code.

I also wrote a little tool (https://github.com/luni64/Board2Make) which extracts the info from boards.txt and converts it into a make-compatible format. So switching between different boards, or optimizer settings etc. is as easy as with the Arduino IDE. The most important thing for me is that this setup allows for self contained projects (I usually copy all used libraries and the Teensy core to the project directory). So, no dependency on the IDE, Arduino or Teensyduino version etc. You can open a project years later and be sure that it just compiles and you can continue working.
 
the only trick would be fudging the teensyduino install package into that format

Well that would be quite a trick indeed, since the json-based package does not provide any way to install Teensy's custom USB discovery tools.

I will be talking with the Arduino devs later this week. Not much to report right now.

thanks for the detail.

does this mean nagging them into adding a new "post install hook" to the format ?

It's much more complicated than that. Sorry, don't have time to write a lengthy explanation. But I can tell you we're going to soon talk about it.
 
Hey Paul, from what I can tell your discussion with the arduino guys is to provide a one-stop solution to use the arduino-cli like the IDE and build/load the Teensy with the one cli.
Is there a way to use the board support files needed for the Teensy with the arduino-cli to compile the hex file and then use the teensy-loader-cli to load the hex file onto the board? I was hoping to perform terminal-only build and board loading.

No. We need Arduino to merge "Pluggable Discovery" before Teensy can be supported. Work was been done on this feature for the IDE, still waiting to be merged.

https://github.com/arduino/Arduino/pull/8038

Cristian said last week he will merge it soon, but plans to alter the JSON format later. Scroll to near the end of that page for details.


Of course, after they merge this into the IDE, it's also needed on the CLI. Cristian & Luca said that's what they intend to do. But it's a slow process. I do not have any idea of the time frame for the CLI to gain the Pluggable Discovery feature. But I would be amazed if it happens within the next few months.

Did you know the IDE can be run from the command line? It's not fast due to the Java JRE startup, but it can be done.
 
No. We need Arduino to merge "Pluggable Discovery" before Teensy can be supported. Work was been done on this feature for the IDE, still waiting to be merged.

Thank you for explaining, I apologize for asking a question which you already answered. I was hoping there was a way to disconnect the two: board support and discovery methodology. I will await this functionality to be integrated in the future.

Fantastic, I did not know that, thank you!

Well, you can, more or less. Just run arduino-builder. In the IDE, turn on verbose output while compiling to see how the IDE runs it.

That will let you do the build part, but not the rest which the IDE and CLI do.
 
Hello Paul,

I see that the Teensy 3.2 is detected by arduino-cli as

Code:
        FQBN    Port            ID              Board Name
        /dev/ttyACM0    16c0:0483       unknown

Is there a way to make arduino-cli download all supporting files by adding an url to the "cli-config.yml" file, as done for the esp8266com?

Code:
board_manager:
  additional_urls:
    - http://arduino.esp8266.com/stable/package_esp8266com_index.json

or can the files / libraries be installed manually ?

The primary goal is to compile for Teensy 3.2 with "arduino-cli", not using "arduino" (which is slow to use, as "command line")

The secondary goal is to program the board via the arduino-cli.

Any advice or direction-pointing is fine.

Thank you.
