    • 1. Example Code for Arduino-I/O Output

    Discover how to configure Arduino I/O Output in single and double threshold modes. Learn about TX/RX complementary levels and their interaction with UART mode. Understand how to switch modes for optimal device performance. Perfect for developers looking to enhance their projects with effective I/O management.
    2. Example Code for Arduino-IIC Output

    This project demonstrates using the IIC communication mode of the TOF Laser Ranging Sensor-25m. In this mode, the controller sends a read frame to the sensor with the specified slave address to obtain distance and other related information following the NLink_TOFSense_IIC_Frame0 protocol. Users will learn how to connect the sensor to an ESP32 via IIC and read data from the sensor.
    3. Example Code for Arduino-UART Query Output

    This project demonstrates using the UART Query Output mode of the TOF Laser Ranging Sensor-25m. In this mode, the sensor does not actively report data; instead, it outputs a frame of measurement information only when receiving a query command containing the module ID. Users will learn how to send query commands from an ESP32 to the sensor and decode the returned data.
    4. Example Code for Arduino-UART Active Output

    This guide focuses on setting up the TOF Laser Ranging Sensor with an ESP32 board for UART active output. It includes steps for hardware and software preparation, wiring, and sample code for data reading and output. Learn how to configure the sensor for precise distance measurement at 50 Hz. Ideal for enhancing projects with accurate serial communication and sensor data integration.
