Hi, I just wanted to check out VS Micro. However, I have run into an issue right away. I have done the following. 

1. Installed the latest Arduino IDE
2. Installed esp32 via Arduino IDE Boards Manager
3. Installed teensyduino from the installer
4. Opened VS micro and refreshed the toolchain.

Now I can select both Arduino and Teensy boards from the list, but I cannot select ESP boards. Everything works fine in Arduino IDE.

Any ideas?

The difference between Teensy boards and ESP is that ESP got installed in the user profile and not in program files. Like this:

%appdata%\Local\Arduino15\packages\esp32\

Thanks

ps: Arduino only saves it's board config when you close the IDE. So if you have added a json url for esp32 then installed esp32 and not shutdown the arduino ide then we will not see the esp boards. Close arduino IDE and then click rescan or restart VS.

Sorry for not being clear. The instructions for enabling verbose compile with build properties are shown in yellow at the top of this page.

However we might not need it. This is standard config so we obviously have some confusion somewhere.

You only need to specify the location of the arduino ide in the visual micro config dialog. The sketchbook folder and board support package urls are inherited from the arduino ide but can optionally be overridden in visual micro. You do not need to override the sketchbook folder.

The sketch book folder is an arduino term for where your projects are saved and user installed libraries are stored. The default is myDocuments\Arduino

Can you please open the visual micro platform explorer then click the IDE Locations button (might need to make it wider to see the button). In the board support urls field for arduino 1.6/1.8 enter the path to the esp32 json file you have used. Also tell us here what url you have used? Is it the standard stable branch or some other?

After entering the url close the IDE locations dialog, make sure Arduino1.6/1.8 is selected in the platform explorer then click the Board Manager tab and install the esp32 toolchain by clicking on it in the board manager tree.

Normally installing the toolchain is not required because it is already installed into the arduino ide but this test can be a way to see errors and issues.

I see thanks. I think the issue we need to investigate is what happens when two copies of the same toolchain is installed. That should not be possible because both the arduino and the visual micro board manager always remove previous and install new when you request to install new platforms.

Please delete %appdata%\Local\Arduino15\packages\esp32\

Then restart the ide just to be clean, then install the latest esp32 toolchain using board manager. Click rescan after the install or restart the ide.

Thanks

Hm, that indeed helped. However, no I am not able to install ESP Async Webserver library for ESP32, it does not find it. But I am quite sure it was visible by the Manage libraries tab before... I can of course install it manually, but it's a bit strange.

Thanks
