Development Methods​

The ESP32-C5-Touch-LCD-3.5 supports two development frameworks, Arduino IDE and ESP-IDF, which can be chosen according to project requirements.

Arduino is suitable for rapid prototyping and basic functionality verification, while ESP‑IDF provides more comprehensive project configuration, debugging, and low‑level control capabilities, making it better suited for complex project development.

  • Arduino IDE is an open-source electronics prototyping platform that can be used to compile, flash, and debug Arduino examples. For environment configuration, see Working with Arduino.

  • ESP-IDF stands for Espressif IoT Development Framework, a development framework provided by Espressif Systems for ESP series chips, including a compiler, debugger, and flashing tools. It supports development via command line or Visual Studio Code with the Espressif IDF plugin. For configuration, see Working with ESP-IDF.
