After download, remove the jumper on IO0 and GND. 8. Power up the RF testing board again. The module will switch to working mode. The chip will read programs from flash upon initialization. Note:

IO0 is internally logic high. If IO0 is set to pull-up, the Boot mode is selected. If this pin is pull-down or left floating, 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:

1 2 sudo yum -y update && sudo yum install git wget flex bison gperf python3 python3-

pip python3-setuptools cmake ninja-build ccache dfu-util libusbx Ubuntu and Debian:

sudo apt-get install git wget flex bison gperf python3 python3-pip python3-

setuptools cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0 sudo pacman -S --needed gcc git make flex bison gperf python-pip cmake ninja ccache dfu-util libusb 1 2 Arch:

1 2 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 1 mkdir -p ~/esp 2 cd ~/esp 3 git 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. 1 cd ~/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:

1 cd ~/esp 2 cp -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:

1 ls /dev/tty*

Espressif Systems 10 Submit Documentation Feedback ESP32-S3-MINI-1 & MINI-1U User Manual v0.6 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. 1 cd ~/esp/hello_world 2 idf.py set-target esp32s3 3 idf.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 --helpfor further information. 3.4.4 Build the Project Build the project by running:
