Working with ESP32

Working with Arduino

Environment Set-up

• Install Arduino IDE.

• Enter Arduino IDE after installation.

• Go to the board manager, search for esp32, select the latest version of esp32 by Espressif Systems at the bottom, and click install (if it doesn't install correctly, you can try using a phone hotspot).

• Restart the Arduino IDE after installation, and then you can use it.

If the installation fails

• Failed to install 2.0.11 version:

• Download the resource file:

• Click on the path "c:\Users\Waveshare\AppData\Local\Arduino15\packages" (where Waveshare is the user name of the computer, and you need to turn on Show Hidden Files).

• Unzip the downloaded files to the packages file folder:

• Install it again:

• Restart the Arduino IDE after installation and you're ready to go!

Run Example

Create Example

• Above, change the project folder to c:\Users\Waveshare\AppData\Local\Arduino15\packages (where Waveshare is the computer username).

• Restart Arduino IDE.
• Demos can be created from the examples in the Project folder under Files.

• The following is the RGB flashing example (File -> Sketchbook -> esp32 -> hardware -> esp32 -> 2.0.11 -> libraries -> ESP32 -> examples -> BlinkRGB under GPIO).

Upload Demo

• Select the development board and port.

• Search esp32s3, select ESP32S3 Dev Module, and the ports to download.

• After selecting, click to upload and Arduino IDE will start to compile and program the demo.

• After uploading, you can see the effect on the development board.

Examples

The following demonstrates device control on the Arduino IDE

Library Installation

• Install Adafruit NeoPixel library:

• Install Adafruit NeoMatrix library:

• Install ALL:

• Install Adafruit GFX Library:

• Install ALL:

• Install FastLED library:

• Install SensorLib library for QMI8658:

Display Characters

• Install Corresponding Library Files
• Download Sample Demo, the examples in the Font folder in the example are for mobile display characters.
• As shown below, 26 lowercase characters displayed as follows:

• The characters inside the quotation marks can be modified to display the corresponding characters on the ESP32-S3-Matrix.
• After modification, upload the demo and use.

Dynamic Game

• Install the corresponding library files.
• Download sample demo, The example in the "Game" folder of the sample is a small game where a light bead moves aligning with the tilt of ESP32-S3-Matrix.
• Uploading the demo and use it.
• After successfully uploading the demo, a bead will be on near the center position.
• The lit bead will move according to the current tilt angle of the device.
• The demo can be modified according to the requirement to achieve more complex operations.

RGB Color

• Install the corresponding library files.
• Download the sample demo. The example in the "Color" folder of the sample is a rather cool color flow.
• Upload the demo and use it.
• After successfully uploading the demo, the board will display colors in a flowing state.
• The demo can be modified according to requirements to achieve more complex operations.

Web Page Control

• Install the corresponding library files.
• Download the sample demo. The example in the "HTTP" folder of the sample allows controlling ESP32-S3-Matrix display via a web page.
• Uploading the demo to use it. Once the demo is successfully uploaded, follow the instructions below to control the device (phone, computer, etc.) to connect to the WIFI named ESP32-S3-Matrix.

• Once successfully connected to the WIFI, you can enter the ESP32-S3-Matrix control page by typing "10.10.10.1" into your browser's address bar and pressing Enter.

 10.10.10.1

• The web page contains two global refresh buttons for controlling ESP32-S3-Matrix, as well as a text box and a submit button.

• After entering characters into the text box, clicking the Submit button will cause the characters in the text box to flow and display on the ESP32-S3-Matrix.
