    Notes: The 10.1-inch LCD screen for the car dashboard and the STONE LCD screen combined with RTL8762CJF MCU are used to develop and make an onboard display dashboard.

    Introduction
    In the process of daily use of the car, we need to always understand the state of the car, to avoid damage to the important parts of the car, but also to eliminate potential dangers. Often, the information displayed on the dashboard is a way to know the state of the vehicle.

    This time I’m going to use a 10.1-inch TFT LCD screen to make an onboard display dashboard. As we all know, the development of STONE intelligent TFT LCD module display is convenient and quick, without too many tedious instructions. This is not only suitable for the majority of learning enthusiasts, but in the actual project can speed up the development, save development time, quickly occupy the market.

    I use the more commonly used RTL8762CJF SCM to develop, through IIC or serial port to achieve the purpose of uploading data to the TFT LCD screen. This time will also use the voice broadcast function, to give the driver a better simulation experience.

    LCD Screen Car Dashboard Project Function
    Here we need to do a used car display project, the project mainly through touch regulation, microcontroller upload instructions manner, simulation with buttons, when MCU button press, through a serial port command to STVC101WT – 01 serial interface screen instructions to upload data, the screen will automatically data parsing, and displayed in the LCD screen. At the same time, there is also a button function on the screen to achieve the serial port instruction, so as to control the MCU.

    In Summary, Five Functions
    The serial port screen realizes the bitmap display function;
    to achieve the dial rotation function;
    to achieve the touch command issued;
    to achieve voice broadcasting;
    to achieve data instruction upload.
    The Function Is Determined, And Then The Module Selection:
    Model of the touch screen;
    what kind of MCU module to use;
    voice broadcast module.
    Hardware Introduction And Principle
    The Horn
    Because the STONE serial port screen comes with an Audio driver and reserved the corresponding interface, so you can use the most common magnet loudspeaker, commonly known as horn. The loudspeaker is a kind of transducer that converts electrical signals into sound signals. The loudspeaker is one of the weakest components in sound equipment and one of the most important components for sound effects. There are many kinds of loudspeakers and the prices vary greatly. Audio electrical energy produces sound by making its paper basin or diaphragm vibrate and resonate (resonate) with the surrounding air through an electromagnetic, piezoelectric, or electrostatic effect.
