Failing to use this to load arduino as a component

[csdarren]

I am pretty new to ESP32 still, having only done simple blink scripts in the past through other IDE's like arduino and platformio, I saw your project and thought I would dive back into ESP32's since I can stay inside neovim now! This is my first experience using esp-idf, and while I understand what is going on pretty well, the project I am trying to flash to my esp32 was built in an .ino arduino file, and my attempts to conver this into an esp-idf project have been very unsuccessful :(

Have you got any experience loading arduino as a component? I have followed espressif's official guide on loading arduino as a component (manually).

I have successfully flashed several non-arduino projects with your tool / manual idf.py terminal commands.

I am currently stuck on idf.py build within the project directory that includes arduino as a component. I have attached my terminal output... Any help is greatly appreciated!

After debugging for the last day, checking so many different things, I think it comes down to how your plugin is setup to use clang instead of GNU. The project I am working on uses the GNU compiler and it seems like when I try to use your plugin to reconfigure it attempts to compile with clang.

I am not smart enough with neovim plugins yet to do anything like this but just making sure to document this in case somebody has this issue in the future.

Hi @csdarren, I have not used Arduino as a component in esp-idf yet. A long time back I started out with Arduino as well, and also used platform.io, which was great at the time! As I figured out how to work with microcontrollers and how things work, I migrated to esp-idf, and lately further to esp-rust. I would like to encourage you to get started with esp-idf, as soon as you cross the initial learning curve barrier, it's fun! Since I'm no active Arduino developer at the time, I can't reliably make this plugin work for Arduino, but if people want to contribute, it would be great to be able to support it.

It's motivating to hear that, I have began learning FreeRTOS, and was already planning on doing exactly that.

Since migrating over to espressifs tooling entirely, I noticed you use IDF_TOOLCHAIN=clang in the reconfigure command. I have been trying to get the clangd lsp to work properly in neovim but have failed to get it going. Could you walk me through how you setup a new project in esp-idf? When I do everything properly according to the documentation to compile with esp-idf's clang beta support, I face an error that says something like "AST -320001" in my snacks notification menu inside neovim. Other than that, I have gotten my code to successfully build and flash using your plugin and I am very excited to dive in and start learning FreeRTOS and then move onto espressifs wonderful esp-idf tooling.

Any help getting clangd working properly would be greatly appreciated! A bit later today I can post some images of what is happening to me

I actually still had it open so here is the errors I am getting. They just get spammed anytime I scroll through my main project.

Can you check if build/compile_commands.json exists? Also, it's important to make sure to use the clangd version provided by Espressif. Check with:

which clangd
clangd --version

This should point the to the ESP folder. Also run the command :ESPReconfigure again in nvim, just to make sure.

Okay I figured out the problem... I had some of your plugins code commented out while I wasnt working with the ESP32, so I didnt get the warnings that it cant find clangd each time I started a file. Is there a way you could make it so that error message only shows up when editing c/c++ files? or another identifier that is more specific to esp32's?

Or maybe it already does this and I had something else going on.

Either way, problem fixed and I appreciate you! Using 'which' is very nice i need to start using that more often during config
