Arduino for STM32

https://blog.arduino.cc/2021/03/01/anno ... -2-0-beta/

I've not tried it yet, but my assumption is that it will probably not work out of the box with this core unless by some miracle it's fully compatible with the original IDE's configuration files.

it seemed to be evolved from the 'pro' ide
https://www.arduino.cc/pro/arduino-pro-ide

apparently it isn't made of java but rather typescript/javascript
https://github.com/arduino/arduino-ide

it seem to suggest where things are headed, it would be more of typescript/javascript based than java.
and quite likely would be more 'cloud' based.

Pipe Dream IMO:

This new IDE was developed with the goal of preserving the same interface and user experience of the previous major version in order to provide a frictionless upgrade.

Also, an opinion, is that Oracle has destroyed JAVA in their fight with Google over Android. Javascript is a great move, but does require heavy browser-side quality testing with any browser code change within the Javascript interpreter.

I recommend staying with 1.8.13 until 2.0 is fully sorted... maybe even longer!

one could say it is 'evolved' from the cloud version (Arduino Create Web Editor)
https://create.arduino.cc/editor/

IDE 2.0 shows that possibly Arduino is moving towards 'cloud' services, and that some of the future features may only be offered in paid 'cloud' services
they could in some ways compete with the likes of IFTTT cloudmqtt etc and offer commercial solutions (libraries?) which are not distributed open sourced

I downloaded and tried to code some encoder stuff onto a Nucleo L476 board.

Starting from a Arduino 1.8 installation with stm32duino I downloaded IDE 2.0 and started the new IDE.

After adding the the STM32Duino additional board manager path https://github.com/stm32duino/BoardMana ... index.json to the preferences and kicking the board manager twice the stm32duino boards were added to board selection and specific board fro board part number. After this build and upload was smooth.

My private changes to add extra board configurations was not recognized.

Debug worked using ST-Link 2 on Nucleo boards after selecting debug ( -g ) in optimize menu. Needed some work to add a launch.json config pointing to the actual build directory. I didnt record every step from scratch so cannot give good instructions but I managed to get debugging with breakpoints working.

Would you mind to post the launch.json config?

The path to the executable is grabbed from the last build output before loading the binary to the board.

Compilation complete.

This is really useful, I was mucking about with cortex-debug trying to get it to work in vscode and figured I'd need to do something like this, but are you having to manually update the launch.json every time, is there not some way for arduino to pass in the current build folder in variable-ised form? I assume you're referring to vscode, can't imagine IDE 2.0 uses intellisense? EDIT - OK so I guess it does with them both being Theia based, anyhow same applies, surely there's some keyword that can be used to refer to the build directory.

Looks like you can get the elf filename using a keyword, and can force the build dir in the arduino prefs - saves having to much about with the launch.json every time...

See here -> for some info https://gist.github.com/robotdad/7e573a ... 184141afaf

Whether this is transferable from vscode to IDE 2.0 I dunno.

I'll give it a try when I get chance.
