Thanks to the nascent Arduino CLI there is now a potentially much more efficient mode of coding for the Arduino. But for larger application development it doesn't compare with a full-featured C/C++ IDE, lacking features such as code navigation, auto-completion, version control integration, or an integrated terminal. It has just enough integrated tools to help achieve that purpose. The Arduino IDE is great at achieving its intended purpose: It's a simple, single-file application development environment. Regarding supported / unsupported extensions I will need more time to explore and will eventually add to this post later on. That's basically it, from here on everything works fine, even on my old Raspberry Pi 2 Model B. Click on the indicator to bring up a list of Remote extension commands. This indicator tells you in which context VS Code is running (local or remote). Once done there's a new symbol in the left toolbar and an indicator on the bottom-left corner of the Status bar. You also need to install the VS Code Remote - SSH extension. Remote Development with Visual Studio Codeįor remote development to work in VS Code, you need to be able to SSH into your Raspberry, or other remote machine, using ssh in a command prompt (Windows) / terminal (Linux). With the nascent Arduino CLI you can even largely replace the Arduino IDE for developing Arduino sketches on RPi and pushing them to a connected Arduino. Remote development solves this by allowing you to code on your desktop / laptop and run it externally on a host (like the RPi). Still, I found developing code on it to be uncomfortable and sometimes cumbersome, as some IDEs don't support ARM processors whereas others like Thonny are rather basic. I have been a fan of the Raspberry Pi single board computer for a number of years now, and have used quite a number of them in my desktop single board computer cluster and my developing Raspberry/Arduino robot car. After the initial work to establish the formula, the formula updates are now done completely automatically as part of the release process.In this short note I will summarize how I can happily use Visual Studio Code on my local Windows desktop or laptop to do remote development on a Raspberry Pi or another Linux machine, and even push Arduino sketches from the Raspberry to an Arduino without touching the Arduino IDE. One interesting thing is that Arduino CLI does have an officially maintained Homebrew formula. But even automated systems require some care and feeding from time to time to keep them running. I think that issue could probably be mitigated to a large extent by taking the time up front to automate the system as much as possible. But you still have the issue of the package maintainer getting busy with other things and not keeping the package up to date. I have more optimism about how that will turn out because Arduino CLI doesn't have all these bundled dependencies, so should be able to be packaged without any modifications at all. There was recently a community effort to create a package for Arduino CLI. But the package manager's don't allow that because each of those dependencies already have their own packages. The Arduino approach is to make things as easy as possible by making it so that when you install the Arduino IDE you get everything you need to start working with the AVR boards right away: Java, avr-gcc, avrdude, etc. I believe 's effort on AUR packets is the way to go we could add a wrapper to easily create deb packages in the repo itself to ease rebuilding, but we need some advice from the actual Debian/Ubuntu/Raspbian packagers to do the right thing. We have a huge dependency problem, mostly due to the fact that the "zero external dependencies" approach started by bundling the JRE helps the beginners but becomes a PITA for repackagers. There was also some interesting information about why these modifications to the IDE are necessary before it can be accepted into the package repositories: I mostly agree with you, but historically it has always been the distribution's maintainer duty to compile and package the supported applications. The response from one of Arduino's firmware developers: Even beyond this license issue, it just seems like having 3rd parties making random modifications to the IDE and not keeping the packages updated leads to many more problems than if the Arduino IDE was only available for download from Arduino's website. Yes, it's another job, but if you're going to present a keynote speech at the Embedded Linux Conference titled "Arduino & Linux: A Love Story", well. My feeling is that either Arduino needs to take an official role in maintaining the Linux packages or else the packages should be removed.
