Problems solved by technology
This type of in-vehicle multimedia device has a disadvantage: it cannot achieve a dynamic display effect similar to sliding, and the display is too rigid and monotonous, which makes the customer feel unintuitive and inflexible when touching.
[0003] The current car multimedia devices can achieve dynamic display effects only based on the ARM architecture car multimedia and graphics display chip-based car multimedia devices, but the price is much higher than the single-chip car multimedia

Embodiment
[0033] A kind of image sliding display method based on single-chip computer vehicle-mounted multimedia equipment in this embodiment is based on common single-chip computer vehicle-mounted multimedia equipment, such as figure 1 As shown, the device includes: a touch screen, a touch chip (AK4183), a screen driver chip (TW8816) and a single-chip microcomputer (MN10131G), and the touch screen, touch chip, and screen driver chip are connected to the single-chip microcomputer respectively.
[0034] Such as figure 2 Shown, a kind of image sliding display method of the vehicle-mounted multimedia device based on single-chip microcomputer of the present invention, comprises the following steps:
[0035] (1) The touch chip reads the coordinates of the current touch point on the touch screen;
[0036] (2-1) With the initial touch point of one continuous sliding as the starting point, the single-chip microcomputer judges the horizontal movement direction of the current touch point relati...

The invention discloses an image slide display method of vehicular multimedia equipment based on a single chip. The method comprises the following steps: (1) reading the coordinates of the current touch point on a touch screen; (2) judging the horizontal moving direction of the current touch point relative to a starting point which is the starting touch point of a continuous slide; if the currenttouch point moves leftwards, changing the horizontal valid display pixel of the image signal, and executing the step (3); if the current touch point moves rightwards relative to the starting point, changing the horizontal non-display pixel of the touch screen, and executing the step (3); and if the image is static, executing the step (3); and (3) repeating the steps (1) and (2). Compared with theprior art, the method disclosed by the invention has the advantage of realizing image slide display without increasing the equipment hardware cost.
Description
technical field [0001] The invention relates to the field of image dynamic display, in particular to an image sliding display method for a vehicle-mounted multimedia device based on a single-chip microcomputer. Background technique [0002] SCM in-vehicle multimedia equipment is generally composed of decoding chip, MCU, touch screen, screen driver chip, and touch chip. This type of in-vehicle multimedia equipment is popular because of its low price, and has a high market share in the current market. This type of on-board multimedia device outputs video signals to the screen driver chip through the decoder chip, and the MCU controls the screen driver chip to display the video signal on the screen. This type of in-vehicle multimedia device has a disadvantage: it cannot achieve a dynamic display effect similar to sliding, and the display is too rigid and monotonous, making it unintuitive and inflexible for customers to touch and operate. [0003] The current car multimedia dev...
