ESP32-C3-MINI-1 & ESP32-C3-MINI-1U Datasheet .
2.3 Set up Development Environment
The Espressif IoT Development Framework (ESP-IDF for short) is a framework for developing applications based on
the Espressif chips. Users can develop applications with ESP chips in Windows/Linux/macOS based on ESP-IDF.
Here we take Linux operating system as an example.
2.3.1 Install Prerequisites
To compile with ESP-IDF you need to get the following packages:
• CentOS 7:
1sudo yum install git wget flex bison gperf python cmake ninja-build ccache dfu-
util
• Ubuntu and Debian (one command breaks into two lines):
1sudo apt-get install git wget flex bison gperf python python-pip python-
setuptools cmake
2ninja-build ccache libffi-dev libssl-dev dfu-util
• Arch:
1sudo pacman -S --needed gcc git make flex bison gperf python-pip cmake ninja
ccache dfu-util
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.
2.3.2 Get ESPIDF
To build applications for ESP32-C3-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’:
1mkdir -p ~/esp
2cd ~/esp
3git clone --recursive https://github.com/espressif/esp-idf.git
Espressif Systems 8 ESP32-C3-MINI-1U User Manual v0.1
2 Get Started on ESP32-C3-MINI-1U
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.
2.3.3 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
2.3.4 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-C3-MINI-1U module.
2.4 Create Your First Project
2.4.1 Start a Project
Now you are ready to prepare your application for ESP32-C3-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 $IDF_PATH/examples/get-started/hello_world .
There is a range of example projects in the examples directory in ESP-IDF. You can copy any project in the same
way as presented above and run it. It is also possible to build examples in-place, without copying them first.
2.4.2 Connect Your Device
Now connect your ESP32-C3-MINI-1U module to the computer and check under what serial port the module is
visible. Serial ports in Linux start with ‘/dev/tty’ in their names. Run the command below two times, first with the
board unplugged, then with plugged in. The port which appears the second time is the one you need:
1ls /dev/tty*
Note:
Keep the port name handy as you will need it in the next steps.
2.4.3 Configure
Navigate to your ‘hello_world’ directory from Step 2.4.1. Start a Project, set ESP32-C3 as the target and run the
project configuration utility ‘menuconfig’.
Espressif Systems 9 ESP32-C3-MINI-1U User Manual v0.1
2 Get Started on ESP32-C3-MINI-1U
1cd ~/esp/hello_world
2idf.py set-target esp32c3
3idf.py menuconfig
Setting the target with ‘idf.py set-target esp32c3’ should be done once, after opening a new project. If the project
contains some existing builds and configuration, they will be cleared and initialized. The target may be saved in
environment variable to skip this step at all. See Selecting the Target for additional information.
If the previous steps have been done correctly, the following menu appears:
Figure 3: Project Configuration  Home Window
The colors of the menu could be different in your terminal. You can change the appearance with the option ‘-�-style’�.
Please run ‘idf.py menuconfig -�-help’�for further information.
2.4.4 Build the Project
Build the project by running:
1idf.py build
This command will compile the application and all ESP-IDF components, then it will generate the bootloader,
partition table, and application binaries.
1$ idf.py build
