How do I change my project?

hans · February 25, 2021, 9:34pm

Yes, I found it. Another thing: When I compile the Blink sketch it gives an error on the “#include Arduino.h” saying "#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (E:\Documents\PlatformIO\Projects\Blink_LED\src\main.cpp).C/C++(1696)
cannot open source file “Arduino.h"C/C++(1696)”.
I suppose I have to make an addition to some Path variable but where do I do it+

maxgerhardt · February 25, 2021, 9:50pm

No, the .vscode/c_cpp_properties.json is automatically managed by PlatformIO so that all frameworks paths are exposed to the IntelliSense.

Does the project build? Only if not, you have a real probem (like a corrupted toolchain).

hans · February 25, 2021, 10:15pm

Your Arduino package is broken. Remove the folder C:\users\hans.platformio\packages\framework-arduinoespressif32\ folly, then build the project.

hans · February 27, 2021, 4:06pm

I removed the file and tried to build again: command ‘platformio-ide-build’ not found

maxgerhardt · February 27, 2021, 4:07pm

Did you try reopening VCode? Seems like some metafiles are broken.

Are any other extensions installed besides PlatformIO and C/C++ by microsoft?

hans · February 27, 2021, 4:16pm

I tried again without having done anything and it seems to have been half successful. Errors: There’s something missing in the path and that’s why it can’t find Arduino.h (I think).

Does the file C:\Users\hans\.platformio\packages\framework-arduinoespressif32\cores\esp32\Arduino.h exist? If not, the toolchain is still broken.

hans · February 27, 2021, 4:21pm

Yes, Arduino.h is there.

maxgerhardt · February 27, 2021, 4:22pm

Try and press Ctrl+Shift+P in VSCode, type “Rebuild”, then press enter. Does the error go away? What’s the full content .vscode/c_cpp_properties.json?

hans · February 27, 2021, 4:27pm

It actually says SUCCESS. I think the 2 problems are from a previous build. I looked for a way to clear the output windows but couldn’t find it. I think it works now.

hans · February 27, 2021, 4:31pm

No, there’s still something with the includePath. How do I add to it?

hans · February 27, 2021, 6:50pm

I created another identical project and now the squiggly line under Arduino.h is gone. Another error popped up; Please specify upload port. I can see that a lot op people have this problem but haven’t seen any solution.

PlatformIO doesn’t see a connected board / serial port. Is the Mega plugged in?

hans · February 27, 2021, 7:00pm

Thanks maxgerhardt but it was a simple problem. The USB plug in my MEGA2560 board wasn’t properly inserted. It works now.

hans · February 28, 2021, 7:57pm

I have the same problem again, now with a ESP32 board. It can’t find Arduino.h. I looked in %userprofile%.platformio\packages\framework-arduinoespressif32 and it is not in there. It seems to me that is the problem. Am I right about that?

You’ve created an ESP-IDF project (framework = espidf), there it’s normal that there’s no Arduino.h. (Though if framework-arduinoespressif32 is again missing, something is really wrong somewhere… Antivirus?)

If you want to use ESP-IDF, see this for a basic example. Otherwise, just create a new ESP32 project and select
Arduino as the framework.

hans · March 1, 2021, 6:53pm

Thanks maxgerhardt
I changed to ‘arduino’ and that did the trick but I find it difficult to decide what to choose. Here are some thoughts:

Board
I have a esp32 board, sometimes called LOLIN32 and it has a processor esp32-Wroom-32 and an on-board OLED display. There is no marking on the board. How can I tell what board to choose. There’s a handful that sound plausible. I just happened to pick one that works, ‘esp32dev’. If things work with another board I don’t know.

Framework
How do I know here that I should not pick the one nameed ‘Espressif32 IoT Development Framework’? It turned out that ‘arduino’ is the one.

Platform
In my case this was easier since there was just one possible choice, ‘Espressif32’.

maxgerhardt · March 1, 2021, 7:22pm

Per board search the Lolin32 is supported – however I don’t see it having an OLED display in the seller pages. The ESP32 boards are quite generic, the 2 basic ESP32 modules are the WROOM and WROVER variants, wheras the latter just has 8MB PSRAM in the module. I’d say pretty much all ESP32 boards work with the Espressif ESP32 Dev Module board config. The difference when choosing a different board that a different board variant of the Arduino core is used, which as assigns some different default pins.

You can pick that framework you like, but the firmwarecode you write then must be targetting that framework. If you’re working with the Arduino IDE, you’re automatically working with Arduino as the framework, so if you want to write code for that, you need to again chose Arduino in PlatformIO. Here’s a topic discussing some basics about frameworks: Frameworks, platforms, and boards, oh my!

See linked topic. By “Platform”, PlatformIO means the general type of microcontroller (series). The ESP32 chips / modules belong to the Espressif32 platform. A board definition only ever belongs to one platform – the Arduino Uno belongs in the “Atmel AVR” platform (since it features an Atmel ATMega328P chip from the AVR series), and to none else.

hans · March 1, 2021, 8:39pm

Thanks again! You supplied a number of useful links. I’ll read, digest and let sink in. I’ll get there eventually.
