Precautions

• GPIO1 and GPIO2 are shared SPI clock/data lines between the LCD and TF. When using the TF card or LCD, ensure proper control of their respective chip select signals.
• GPIO18 and GPIO19 are the onboard shared I2C bus, already connected to touch and IMU devices. When connecting external I2C devices, be mindful of address conflicts, pull-up resistors, and bus voltage levels.
• GPIO8 is the chip boot mode control pin. The official FAQ suggests: if the program occupies this pin and prevents programming, temporarily connect GPIO8 to 3V3 and re-enter download mode.
• GPIO12 and GPIO13 are USB D-/D+; do not use them as general-purpose GPIO when using USB functionality.
• GPIO16 and GPIO17 are connected to UART0, typically used for serial communication or debug output.
• GPIO0 is connected to the battery voltage sampling circuit; when reusing as a general-purpose ADC/GPIO, consider the impact of the voltage divider network on the signal level.
• GPIO5 and GPIO6 are connected to QMI8658A interrupt outputs; consider IMU interrupt configuration when reusing these pins.
• Before connecting a battery, verify the battery polarity and type. Do not connect VBAT directly to 3V3 or USB VBUS.
• TF cards should be formatted as FAT32. When the LCD and TF share the SPI bus, keep the chip select of the inactive device in an inactive state.

Development Methods

The ESP32-C6-Touch-LCD-1.47 supports both the Arduino IDE and ESP-IDF development frameworks, giving developers flexible options. You can choose the development tool that best suits your project needs and personal preferences.

Arduino generally offers a gentler learning curve and may be more approachable for beginners and hobbyists. ESP-IDF provides advanced tooling and finer control over system behavior, making it better suited to complex projects and applications with demanding performance requirements.

• 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 huge global user community, providing a vast amount of open-source code, project examples, and tutorials, as well as a rich library ecosystem that encapsulates complex functions, enabling developers to implement various features rapidly. You can 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 a professional development framework launched by Espressif Systems for its ESP series of chips. It is based on C language development and includes compilers, debuggers, flashing tools, etc. It supports development via command line or integrated development environments (such as Visual Studio Code with the Espressif IDF plugin), which provides features like code navigation, project management, and debugging. 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 example programs for reference.
