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:
sudo yum install git wget flex bison gperf python cmake ninja-build ccache dfu-
1
util
• Ubuntu and Debian (one command breaks into two lines):
sudo apt-get install git wget flex bison gperf python python-pip python-
1
setuptools cmake
ninja-build ccache libffi-dev libssl-dev dfu-util
2
• Arch:
sudo pacman -S --needed gcc git make flex bison gperf python-pip cmake ninja
1
ccache dfu-util
Note:
• This guide uses the directory
• Keep in mind that ESP-IDF does not support spaces in paths.
2.3.2 Get ESP­IDF
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 (
clone':
mkdir -p ~/esp
