Getting Start

Two method to Getting Start

Under normal circumstances, people program the ESP32-S3 using the methods described in the following sections, either by using the official IDF programming process or by using the Arduino IDE with plugins. Today, however, we will guide you through using the more streamlined ESPHome approach for an easier programming experience. Here, you can choose your preferred method to proceed.

Method No.1 (Normal circumstances)

The ESP32-S3 is a powerful SoC for IoT applications, offering a rich set of features. This guide will help you get started with your first ESP32-S3 project.

What You Need

  • ESP32-S3 Development Board: Any ESP32-S3 board will do, such as the ESP32-S3-DevKitC-1.
  • USB Cable: To connect the board to your computer.
  • Computer: Running Windows, Linux, or macOS.
  • Development Environment: ESP-IDF (Espressif IoT Development Framework) or Arduino IDE.

Setting Up the Hardware

  1. Connect the ESP32-S3 Board: Use the USB cable to connect the ESP32-S3 board to your computer.
  2. Power On: Some boards may require an external power source; ensure your board is powered on.

Installing Software

ESP-IDF
  1. Install prerequisites: Depending on your OS, install the necessary prerequisites for ESP-IDF.
  2. Download and Install ESP-IDF: Follow the installation instructions for your OS from the ESP-IDF Programming Guide.
  3. Set up the environment: Configure the environment variables for ESP-IDF.
Arduino IDE
  1. Install Arduino IDE: Download and install the Arduino IDE from the official Arduino website.
  2. Add ESP32 Board Manager: Open Arduino IDE, go to File > Preferences, and add the ESP32 Board Manager URL.
  3. Install ESP32 Board: Go to Tools > Board > Boards Manager, search for ESP32, and install.

First Project: Blinking LED

ESP-IDF

  1. Create a new project: Use the idf.py command to create a new project or open an existing one.
  2. Edit the main application: Locate the main.c file and write your application code.
  3. Build and Flash: Use the idf.py build and idf.py -p PORT flash commands to build and flash the firmware.

Arduino IDE

  1. Select the board: Go to Tools > Board and select your ESP32-S3 board.
  2. Write the sketch: Use the following code to blink an LED connected to GPIO2:
#define LED_PIN 2

void setup() {
  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_PIN, HIGH);
  delay(1000);
  digitalWrite(LED_PIN, LOW);
  delay(1000);
}
  • Upload the sketch: Click the Upload button to program the ESP32-S3.

Troubleshooting

  • Driver Issues: Ensure you have the correct drivers installed for your ESP32-S3 board.
  • Serial Monitor: Use the Tools > Serial Monitor to view output from your ESP32-S3.
