Demo ESP32 S3 board with Arduino environment

Introduction

ESP32-S3-GEEK is an Ethernet development board designed based on ESP32-S3R8. It has excellent Wi-Fi and Bluetooth wireless connection functions, has a more reliable and efficient wired Ethernet connection, and supports PoE power supply (PoE version only). The onboard camera interface is compatible with mainstream cameras such as OV2640 and OV5640, which is convenient for image and video capture. The development board also reserves a Pico-compatible interface, supporting some Raspberry Pi Pico expansion boards. Relying on its rich ecosystem and open-source resources, users can quickly and flexibly perform secondary development. It is widely applicable to Internet of Things, image acquisition, smart home, and artificial intelligence projects.

Download and Install Arduino IDE

This chapter introduces setting up the Arduino environment, including the Arduino IDE, management of ESP32 boards, installation of related libraries, program compilation and downloading, as well as testing demos. It aims to help users master the development board and facilitate secondary development.

• Click to visit the Arduino official website, select the corresponding system and system bit to download.
• Run the installer and install all by default.
  For more instructions on how to use the Arduino IDE, please refer to Arduino Official Documentation

Install ESP32 Development Board

• To use ESP32 boards in Arduino IDE, first install the ESP32 Development Board package.
• In some areas, it may not be able to Install online due to network reason, and Install offline is generally recommended.
• For the tutorial on installing ESP32 Development Board package, please refer to Arduino board manager tutorial
• ESP32-S3-ETH Development board installation instructions

Install Libraries

Run the First Arduino Demo

Run the Arduino IDE and select File -> New Sketch

• Enter the code:

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
}

void loop() {
  // put your main code here, to run repeatedly:
  Serial.println("Hello, World!");
  delay(2000);
}

• Save the project and select File -> Save As.... In the pop-up menu, select the path to save the project, and enter a project name, such as Hello_World, click Save

Compile and Flash Demos

• Select the corresponding development board, take the ESP32S3 motherboard as an example: Tools -> Board -> esp32 -> ESP32S3 Dev Module

• Select the corresponding port. In addition, if ESP32 S3 motherboard only has a USB port, USB CDC must be enabled, as shown in the following figure:

• Compile and upload the demo:

• Open the serial port monitoring window, and the demo will print "Hello World!" every 2 seconds, and the operation is as follows:
