Code Examples for the Espressif ESP32-C3 SoC.
List of content
This repository is a collection of examples for the espressif ESP32-C3 SoC.
It is structured in a way that you find a empty main.cpp file, because it is not a specific repository. Instead you find all examples in the examples folder.
From there you can copy an past the code easily to the main.cpp file
You can install/clone the repo by th following command.
git clone https://github.com/hasenradball/ESP32-C3-Examples.git
After the cloning the repository please do the following on your local repo to prevent the files to be tracked and pushed.
git update-index --assume-untracked src/main.cpp
git update-index --assume-untracked include/wifi_secrets.h
The focus for this repository is to use the Arduino Core for ESP32 v3.x. Therefore it is recommended to use the Configuration for Arduino core v3.x. With v3.x there are some braking changes which means that not all examples will directly run on v2.x and need code adaption.
For the usage of the Arduino Core v3.0.7 the following configuration should be used.
[env:esp32-c3-devkitm-1]
board = esp32-c3-devkitm-1
platform = espressif32
platform_packages =
platformio/framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#3.0.7
platformio/framework-arduinoespressif32-libs @ https://github.com/espressif/esp32-arduino-lib-builder/releases/download/idf-release_v5.1/esp32-arduino-libs-idf-release_v5.1-632e0c2a.zip
framework = arduino
build_flags =
-DARDUINO_USB_CDC_ON_BOOT=1
-DARDUINO_USB_MODE=1
