Development Methods​

ESP32-C5-Touch-LCD-1.69 supports both Arduino IDE and ESP-IDF development frameworks.

  • Arduino IDE is an open-source electronics prototyping platform with rich community resources, offering a large number of open-source code examples, projects, and libraries. Refer to the Working with Arduino to complete the initial setup, and the tutorial also provides related example programs for reference.

  • ESP-IDF, short for Espressif IoT Development Framework, is the development framework launched by Espressif Systems for its ESP series of chips. It is based on C language and includes compilers, debuggers, flashing tools, etc., supporting development via command line or integrated development environments (such as Visual Studio Code with the Espressif IDF plugin). VS Code is recommended for development; refer to the Working with ESP-IDF for the detailed configuration process, which also provides relevant example programs.
