ESP32-S3 Series Datasheet.
3.3 Set up Development Environment
The Espressif IoT Development Framework (ESP-IDF for short) is a framework for developing applications based
on the Espressif ESP32. Users can develop applications with ESP32-S3 in Windows/Linux/macOS based on
ESP-IDF. Here we take Linux operating system as an example.
3.3.1 Install Prerequisites
To compile with ESP-IDF you need to get the following packages:
• CentOS 7 & 8:
1sudo yum -y update && sudo yum install git wget flex bison gperf python3 python3-
pip
2python3-setuptools cmake ninja-build ccache dfu-util libusbx
• Ubuntu and Debian:
1sudo apt-get install git wget flex bison gperf python3 python3-pip python3-
setuptools
2cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0
• Arch:
1sudo pacman -S --needed gcc git make flex bison gperf python-pip cmake ninja
ccache
2dfu-util libusb
Note:
• This guide uses the directory ~/esp on Linux as an installation folder for ESP-IDF.
• Keep in mind that ESP-IDF does not support spaces in paths.
3.3.2 Get ESPIDF
To build applications for ESP32-S3-WROOM-1 or ESP32-S3-WROOM-1U module, you need the software
libraries provided by Espressif in ESP-IDF repository.
To get ESP-IDF, create an installation directory (~/esp) to download ESP-IDF to and clone the repository with ‘git
clone’:
Espressif Systems 11
Submit Documentation Feedback
ESP32-S3-WROOM-1 & WROOM-1U Datasheet v0.6
3 Get Started
1mkdir -p ~/esp
2cd ~/esp
3git clone --recursive https://github.com/espressif/esp-idf.git
ESP-IDF will be downloaded into ~/esp/esp-idf. Consult ESP-IDF Versions for information about which ESP-IDF
version to use in a given situation.
3.3.3 Set up Tools
Aside from the ESP-IDF, you also need to install the tools used by ESP-IDF, such as the compiler, debugger,
Python packages, etc. ESP-IDF provides a script named ’install.sh’ to help set up the tools in one go.
1cd ~/esp/esp-idf
2./install.sh
3.3.4 Set up 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 ’export.sh’ which does
that. In the terminal where you are going to use ESP-IDF, run:
1. $HOME/esp/esp-idf/export.sh
Now everything is ready, you can build your first project on ESP32-S3-WROOM-1 or ESP32-S3-WROOM-1U
module.
3.4 Create Your First Project
3.4.1 Start a Project
Now you are ready to prepare your application for ESP32-S3-WROOM-1 or ESP32-S3-WROOM-1U module.
You can start with get-started/hello_world project from examples directory in ESP-IDF.
Copy get-started/hello_world to ~/esp directory:
1cd ~/esp
2cp -r $IDF_PATH/examples/get-started/hello_world .
There is a range of example projects in the examples directory in ESP-IDF. You can copy any project in the same
way as presented above and run it. It is also possible to build examples in-place, without copying them
first.
3.4.2 Connect Your Device
Now connect your module to the computer and check under what serial port the module is visible. Serial ports in
Linux start with ‘/dev/tty’ in their names. Run the command below two times, first with the board unplugged,
then with plugged in. The port which appears the second time is the one you need:
1ls /dev/tty*

Note:
Keep the port name handy as you will need it in the next steps.
3.4.3 Configure
Navigate to your ‘hello_world’ directory from Step 3.4.1. Start a Project, set ESP32-S3 chip as the target and run
the project configuration utility ‘menuconfig’.
1cd ~/esp/hello_world
2idf.py set-target esp32s3
3idf.py menuconfig
Setting the target with ‘idf.py set-target esp32s3’ should be done once, after opening a new project. If the
project contains some existing builds and configuration, they will be cleared and initialized. The target may be
saved in environment variable to skip this step at all. See Selecting the Target for additional information.
If the previous steps have been done correctly, the following menu appears:
Figure 3: Project Configuration  Home Window
You are using this menu to set up project specific variables, e.g. Wi-Fi network name and password, the
processor speed, etc. Setting up the project with menuconfig may be skipped for “hello_word”. This example will
run with default configuration
The colors of the menu could be different in your terminal. You can change the appearance with the option
‘-�-style’�. Please run ‘idf.py menuconfig -�-help’�for further information.
3.4.4 Build the Project

If there are no errors, the build will finish by generating the firmware binary .bin file.
3.4.5 Flash onto the Device
Flash the binaries that you just built onto your module by running:
1idf.py -p PORT [-b BAUD] flash
Replace PORT with your ESP32-S3 board’s serial port name from Step: Connect Your Device.
You can also change the flasher baud rate by replacing BAUD with the baud rate you need. The default baud
rate is 460800.
For more information on idf.py arguments, see idf.py.
Note:
The option ‘flash‘ automatically builds and flashes the project, so running ‘idf.py build‘ is not necessary.
When flashing, you will see the output log similar to the following:
