Hi, a few days ago I found that Visual Studio 2019 already has support for CMake and Ninja.

This is my installation steps for ESP-IDF 4.1 + Visual Studio Community 2019:

Note:

Ninja binary available only for Windows 64 bit
I use Visual Studio Community 2019 Version 16.8.3

Steps:

Download the ESP-IDF Tools installer from https://dl.espressif.com/dl/esp-idf-tools-setup-2.3.exe
Run the installer. I use the default installation folder. My computer did not have Python and Git, so the installer also download and run installers for Python and Git.
Download Visual Studio Community 2019 Installer from Microsoft website. Open the installer. Check 'Desktop development with C++' and 'Linux development with C++' and make sure 'C++ CMake tools for Linux' and 'JSON Editor' are checked. If you want to use Visual Studio only for ESP-IDF and want to minimize download, you can unchecked everything in the Installation details except for 'C++ CMake tools for Linux' and 'JSON Editor'.
Create a new project by copying the hello_world example folder (C:\Users\[your username here]\Desktop\esp-idf\examples\get-started\hello_world) to the place you want (the full directory path should not contain any spaces). I put mine in M:\VisualStudio so the full path is M:\VisualStudio\hello_world (adjust to your project's path).
Right click your project folder in Windows Explorer and select 'Open with Visual Studio' or you can open Visual Studio 2019 from Start menu, choose File - Open - Folder or File - Open - CMake, and select your project folder. Wait until 'CMake Overview Pages' is shown.
Click 'Open the CMake Settings Editor' in the 'CMake Overview Pages' or right click CMakeList.txt in the Solution Explorer and choose 'CMake Settings'
Click 'Edit JSON'

Replace all with this:

```
Save the file
In Visual Studio, right click any file in the Solution Explorer and select 'Run menuconfig'. Change the settings you want.
Save and exit
Select Project - 'Generate Cache for [your project folder name]' from the Visual Studio menu to regenerate CMake cache. I suggest you always regenerate the CMake cache when you are done with menuconfig.
Build using the regular Visual Studio build menu (Build - Build All)
To flash the firmware to ESP32, right click any file in the Solution Explorer and choose 'Run flash'. Choose 'Run monitor' to open monitor. Choose 'Run flash monitor' to flash and open monitor.
When the monitor is opened, the build menu will be disabled. So close the monitor before build again.
In the CMakeSetting.json, I set the build folder not in the 'out' folder. If you follow this setting, you can delete the 'out' folder if it was created by Visual Studio.

If your settings does not become effective or you got strange error, try:

Delete and generate CMake cache again. Sometimes the CMake cache is not updating. Just be patient with this.
Or if you want to force it, close Visual Studio, then delete the build folder and everything in the .vs folder except tasks.vs.json.

The intellisensemode that I use is windows-clang-64.

If you open C file, the Intellisense does not show undefined method or variable.
If you open Cpp file, the Intellisense show undefined method or variable.

Hello,
I've got this working on IDF 4.0, although I get some reference errors.
This is a Visual Studio thing, because the project compiles when right click and choose flash monitor.
Just posting the first few, you get the idea.
Any ideas?

It seems that references to components are also not working

Here is a reference for a simplified and faster method to get ESP-IDF 4.1 to work with VSC.

https://www.esp32.com/viewtopic.php?f=4 ... =10#p70518

Ignore the reference to problems related to Espressif IDF 0.6.0. Those are now fixed in 0.6.1.

Posted: **Tue Jan 26, 2021 9:00 am**

I think it fails to found the include files because the path for ESP-IDF 4.0 is different. Try check the paths in the environment section in CMakeSettings.json in step 8. The easy way to check this is to open "ESP-IDF Command Prompt" (double click shortcut on the Desktop). Then type "set" and ENTER. All the paths will be displayed. This is the way I fill those paths in the environment section in CMakeSettings.json. If you want, you can choose not to use ${env.IDF_TOOLS_PATH} variable and just copy the path from the "ESP-IDF Command Prompt".

This post is about Visual Studio Code, I am interested in Visual Studio. So far I have used, eclipse, VSC and visualgdb. All of them have their pro's and cons for me.

For the pads, I have changed some things in the json in order to make it build. I didn't know about the "set" function. I shall try this later.
EDIT: Just checked, the paths are identical.

BTW, if debugging is possible, that would be awesome.

Could you copy paste the result from the "set" command here? And also the content of your CMakeSettings.json.

Posted: **Wed Jan 27, 2021 3:58 am**

The problem is that Visual Studio CMake can not find the header files. It will search for them in the path specified by the INCLUDE environment variable (see in the CMakeSettings.json). I just tried to run the "set" command again and there was no INCLUDE environment variable there. Sorry I forgot.

For ESP-IDF 4.1, I specify this for the INCLUDE environment variable (in step 8):
"INCLUDE": "${env.IDF_TOOLS_PATH}\\tools\\xtensa-esp32-elf\\esp-2020r2-8.2.0\\xtensa-esp32-elf\\xtensa-esp32-elf\\include;${env.IDF_TOOLS_PATH}\\tools\\xtensa-esp32s2-elf\\esp-2020r2-8.2.0\\xtensa-esp32s2-elf\\xtensa-esp32s2-elf\\include;${env.IDF_PATH}\\components;${env.INCLUDE}",

From the error that you post, Visual Studio CMake can not found the stdint.h, stdio.h, etc files. These files locations for ESP-IDF 4.1 are in the xtensa-esp32-elf and xtensa-esp32s2-elf (depending on the target ESP32). I just installed ESP-IDF 4.0.2 and there is only the xtensa-esp32-elf folder. Inside that folder is the esp-2020r3-8.4.0 folder. This is different from the ESP-IDF 4.1 which is esp-2020r2-8.2.0. So you have to change this to the folder for your ESP-IDF version. For ESP-IDF 4.0.2 the INCLUDE environment variable should be like this:

"INCLUDE": "${env.IDF_TOOLS_PATH}\\tools\\xtensa-esp32-elf\\esp-2020r3-8.4.0\\xtensa-esp32-elf\\xtensa-esp32-elf\\include;${env.IDF_PATH}\\components;${env.INCLUDE}",

@vanBassum

The main motivation for me to record the simplified installation steps was to demonstrate how to get the ESP IDF debugger to work with VSC.

Aha oke, I tried changing the include folder to match the one on my disk. Although its still giving errors.
I've included the SET command and the JSON.
