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

1. The serial port screen realizes the bitmap display function;
2. to achieve the dial rotation function;
3. to achieve the touch command issued;
4. to achieve voice broadcasting;
5. to achieve data instruction upload.

The Function Is Determined, And Then The Module Selection:

1. Model of the touch screen;
2. what kind of MCU module to use;
3. 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.
