Development Methods​

The ESP32-S3-ePaper-3.97 supports two development frameworks: Arduino IDE and ESP-IDF, offering flexibility for developers. You can choose the appropriate development tool based on project requirements and personal preference.

Each method has its advantages, and developers can select based on their needs and skill level. Arduino is simple to learn and easy to get started with, suitable for beginners and non-professionals; ESP-IDF provides more advanced development tools and stronger control capabilities, suitable for developers with professional backgrounds or those with higher performance requirements, and is more suitable for complex project development.

  • Arduino IDE is a convenient, flexible, and easy-to-use open-source electronics prototyping platform. It requires minimal foundational knowledge, allowing for rapid development after a short learning period. Arduino has a vast global community that provides a wealth of open-source code, project examples, tutorials, and rich libraries that encapsulate complex functionalities, enabling developers to implement various features quickly. You can refer to the Working with Arduino to complete the initial setup, and the tutorial also provides related demos for reference.

  • ESP-IDF (Espressif IoT Development Framework) is a professional development framework released by Espressif for its ESP series chips. It is developed based on the C language, including a compiler, debugger, and flashing tool, etc. It supports development via command line or an Integrated Development Environment (such as Visual Studio Code with the Espressif IDF plugin), which provides features like code navigation, project management, and debugging, etc. We recommend using VS Code for development. For the specific configuration process, please refer to the Working with ESP-IDF. The tutorial also provides relevant demos for reference.
