the Download mode is selected. For more information on ESP32-S3-MINI-1 or ESP32-S3-MINI-1U, please refer to

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-MINI-1 or ESP32-S3-MINI-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 9

Submit Documentation Feedback

ESP32-S3-MINI-1 & MINI-1U User Manual 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-MINI-1 or ESP32-S3-MINI-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-MINI-1 or ESP32-S3-MINI-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*

3 Get Started

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 ESP32-S3’ 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

Build the project by running:

1idf.py build

20 or run ’idf.py -p PORT flash’

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:
