Download Arduino IDE from official site and install into your system. We have use Arduino IDE 1.8.19
-
Once installation done will add ESP32 S3 board support into IDE, for this first you need to add below link into preference:
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.jsonSelect File > Preference, and add link as show in below image,
-
Now will install ESP32 based boards as shown in below image,
-
You have two options to program onboard ESP32 of 2x2 display board, UART USB OR Native USB.
-
When using Native ESP USB, you will have to press BOOT button once and then connect Type C. For UART USB no need, directly connect USB.
-
Once done (for UART USB), keeping default settings select the ESP32S3 Dev Module with suitable COM PORT (may be different in your case) as shown below,
You can view assigned COM port through Device Manager,
-
When using USB native you will get COM PORT as shown in below image, and while uploading you can enable CDC Mode to visualize data on serial com port.
-
Download library zip file provided here in github.
-
Extract and copy files inside Document > Arduino > Libraries folder. Make sure to restart Arduino IDE whenever you update or add any libraries.
- At this step you are all set to test codes, for easy getting started we have provided various demo example codes in github which you can download and try.
- Make sure to use relevant example code for your specific board:
- Open one example code in Arduino and make sure you have selected correct board with suitable com port, click on upload button to transfer code on ESP32 of 2x2 Display board.
- Checkout other reference examples, modify, build and share!
