How to use
- Download and install Visual Studio Code.
- Then
- Either open Visual Studio Code and create a workspace folder.
- Run
code ${YOUR_PROJECT_DIR}
from the command line.
- Install this extension in your Visual Studio Code.
Prerequisites
There are few dependencies required in your system and available in environment variable PATH before installing this extension. Please review the following documentation.
- Requirements for Linux
- Requirements for MacOS
- For Windows the C++ Build Tools might be required.
Installation of ESP-IDF and ESP-IDF Tools is being done from this extension itself (existing ESP-IDF installation may also be reused) using the ESP-IDF: Configure ESP-IDF extension setup wizard or following the steps in the setup documentation.
NOTE: Please note that this extension only supports the release versions of ESP-IDF, you can still use the extension on
master
branch or some other branch, but certain feature might not properly work.
NOTE: If you are using Windows Subsystem for Linux (WSL) 2, please take a look at the additional requirements in WSL Documentation needed in the WSL distribution.
-
(OPTIONAL) Press F1 and type ESP-IDF: Select where to save configuration settings, which can be User settings, Workspace settings or workspace folder settings.
NOTE: Please take a look at Working with multiple projects for more information. Default is User settings.
-
On the first time using the extension, press F1 and type ESP-IDF: Configure ESP-IDF extension to open the extension configuration wizard. This will install ESP-IDF, ESP-IDF tools, create a virtual python environment with ESP-IDF and this extension python packages and configure the extension settings with these values. NOTE: Make sure that there is no spaces in any configured path since ESP-IDF build system doesn't support spaces yet..
NOTE: Please take a look at SETUP documentation or the Install tutorial for details about extension setup and configuration.
-
Press F1 and type ESP-IDF: Show Examples Projects to create a new project from ESP-IDF examples.
-
Configure the
.vscode/c_cpp_properties.json
as explained in C/C++ Configuration. There is a default configuration that should work when you create a new project with the extension commands but you might want to modify it to your needs.Note: If you want to get code navigation and ESP-IDF function references, the Microsoft C/C++ Extension can be used to resolve header/source links. By default, projects created with ESP-IDF: Create project from extension template or ESP-IDF: Show Examples Projects tries to resolve headers by manually recursing ESP-IDF directory sources with the
Tag Parser
engine. This can be optimized by building the project first and configure your project to usebuild/compile_commands.json
as explained in C/C++ Configuration.NOTE: You should set
"C_Cpp.intelliSenseEngine": "Tag Parser"
in your settings.json if you are not using the compile_commands.json approach. -
Do some coding!
-
Check you set the correct port of your device by pressing F1, typing ESP-IDF: Select port to use: and choosing the serial port your device is connected.
-
Select an Espressif target (esp32, esp32s2, etc.) with the ESP-IDF: Set Espressif device target command. If you are using one of our boards, use the ESP-IDF: Select OpenOCD Board Configuration to choose the openOCD configuration files for the extension openOCD server.
-
When you are ready, build your project by pressing F1 and typing ESP-IDF: Build your project.
-
Flash to your device by pressing F1 and typing ESP-IDF: Select Flash Method and Flash to select either UART or JTAG. You can also use the ESP-IDF: Flash (UART) your project or ESP-IDF: Flash (with JTag) directly.
NOTE: When using the ESP-IDF: Select Flash Method and Flash command, your choice will be saved in the
idf.flashType
configuration setting. -
You can later start a monitor by pressing F1 and typing ESP-IDF: Monitor your device which will log the device activity in a Visual Studio Code terminal.
-
To make sure you can debug your device, select the your board by pressing F1 and typing ESP-IDF: Select OpenOCD Board Configuration or manually define the openOCD configuration files with
idf.openOcdConfigs
configuration in your settings.json. -
If you want to start a debug session, just press F5 (make sure you had at least build and flash once before so the debugger works correctly). Check the Troubleshooting section if you have any issues.

About commands
-
The Add Arduino-ESP32 as ESP-IDF Component command will add Arduino-ESP32 as a ESP-IDF component in your current directory (
${CURRENT_DIRECTORY}/components/arduino
).NOTE: Not all versions of ESP-IDF are supported. Make sure to check Arduino-ESP32 to see if your ESP-IDF version is compatible.
-
You can also use the ESP-IDF: Create project from extension template command with
arduino-as-component
template to create a new project directory that includes Arduino-ESP32 as an ESP-IDF component. -
The Install ESP-ADF will clone ESP-ADF inside the selected directory and set
idf.espAdfPath
(idf.espAdfPathWin
in Windows) configuration setting. -
The Install ESP-Matter will clone ESP-Matter inside the selected directory and set
idf.espMatterPath
(idf.espMatterPathWin
in Windows) configuration setting. The Set ESP-MATTER Device Path (ESP_MATTER_DEVICE_PATH) is used to define the device path for ESP-Matter. -
The Install ESP-MDF will clone ESP-MDF inside the selected directory and set
idf.espMdfPath
(idf.espMdfPathWin
in Windows) configuration setting. -
The Show Examples Projects command allows you create a new project using one of the examples in ESP-IDF, ESP-ADF, ESP-Matter or ESP-MDF directory if related configuration settings are correctly defined.
Commands for tasks.json and launch.json
We have implemented some utilities commands that can be used in tasks.json and launch.json that can be used like:
"miDebuggerPath": "${command:espIdf.getXtensaGdb}"
espIdf.getExtensionPath
: Get the installed location absolute path.espIdf.getOpenOcdScriptValue
: Return the value of OPENOCD_SCRIPTS fromidf.customExtraVars
or from system OPENOCD_SCRIPTS environment variable.espIdf.getOpenOcdConfig
: Return the openOCD configuration files as string. Example-f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp32-wrover.cfg
.espIdf.getProjectName
: Return the project name from current workspace folderbuild/project_description.json
.espIdf.getXtensaGcc
: Return the absolute path of the xtensa toolchain gcc for the ESP-IDF target given byidf.adapterTargetName
configuration setting andidf.customExtraPaths
.espIdf.getXtensaGdb
: Return the absolute path of the xtensa toolchain gdb for the ESP-IDF target given byidf.adapterTargetName
configuration setting andidf.customExtraPaths
.

Troubleshooting
If something is not working please check for any error on one of these:
NOTE: Use
idf.openOcdDebugLevel
configuration setting to 3 or more to show debug logging in OpenOCD server output.
NOTE: Use
logLevel
in your /.vscode/launch.json to 3 or more to show more debug adapter output.
- In Visual Studio Code select menu "View" -> Output -> ESP-IDF, ESP-IDF Debug Adapter, Heap Trace, OpenOCD and SDK Configuration Editor. This output information is useful to know what is happening in each tool.
- Use the
ESP-IDF: Doctor command
to generate a report of your configuration and it will be copied in your clipboard to paste anywhere. - Check log file which can be obtained from:
- Windows:
%USERPROFILE%\.vscode\extensions\espressif.esp-idf-extension-VERSION\esp_idf_vsc_ext.log
