Step 4. Set up the Environment Variables

The installed tools are not yet added to the PATH environment variable. To make the

tools usable from the command line, some environment variables must be set. ESP-IDF

provides another script which does that.

ESP-IDF Tools Installer for Windows creates an "ESP-IDF Command Prompt" shortcut in

the Start Menu. This shortcut opens the Command Prompt and sets up all the required

environment variables. You can open this shortcut and proceed to the next step.

Alternatively, if you want to use ESP-IDF in an existing Command Prompt window, you

can run:

%userprofile%\esp\esp-idf\export.bat

Step 5. Start a Project

Now you are ready to prepare your applications for ESP32. You can start with

single_chip/recognition_solution project from examples directory in IDF.

Copy single_chip/recognition_solution to ~/esp directory:

cd %userprofile%\esp

xcopy /e /i %IDF_PATH%\examples\ single_chip/recognition_solution

There is a range of example projects in the examples directory in ESP-WHO. You can

copy any project in the same way as presented above and run it.

It is possible to build examples in-place, without copying them first.

Step 6. Connect Your Device

Now connect your ESP32 board to the computer and check under what serial port the

board is visible.

Serial ports have the following patterns in their names:

Windows：names like COM1
