Introduction 1.Introduction 1.1. T-Encoder pro T-Encoder pro is a development board. It can work independently. It consists of ESP32-S3 MCU supporting Wi-Fi + BLE communication protocol and motherboard PCB. The screen is 2.04 inch AMOLED. ESP32-S3 integrates Wi-Fi (2.4 GHz band) and Bluetooth 5.0 solutions on a single chip, along with dual high performance cores and many other versatile peripherals. Powered by 40 nm technology, ESP32-S3 provides a robust, highly integrated platform to meet the continuous demands for efficient power usage, compact design, security, high performance, and reliability. Xinyuan provides the basic hardware and software resources that empowers application developers to build their ideas around the ESP32-S3 series hardware. The software development framework provided by Xinyuan is intended for rapidly developing Internet-of- Things (IoT) applications, with Wi-Fi, Bluetooth, flexible power management and other advanced system features. The T-Encoder pro manufacturer is Xin Yuan Electronic Technology Co., Ltd. 1.2. Arduino A set of cross-platform applications written in Java. The Arduino Software IDE is derived from the Processing programming language and the integrated development environment of the Wiring program. Users can develop applications in Windows/Linux/ MacOS based on Arduino. It is recommended to use Windows 10. Windows OS has been used as an example in this document for illustration purposes. 1.3. Preparation To develop applications for ESP32-S3 you need: •PC loaded with either Windows, Linux or Mac operating system •Toolchain to build the Application for ESP32-S3 •Arduino that essentially contains API for ESP32-S3 and scripts to operate the Toolchain •The ESP32-S3 board itself and a USB cable to connect it to the PC Xinyuan !/121 2023.11 ! 2.
