Embedded system with date and time adjustment function and method for adjusting date and time

Abstract

The invention discloses an embedded system with a stereoscopic rolling type date and time adjustment function. The embedded system comprises a display screen, an area positioning module, a background drawing module, a numerical value sliding processing module and a date and time adapter, wherein the area positioning module is used for specifying the position and the size of a display area of a date or time numerical value on the display screen; the background drawing module is used for drawing a background map layer in the display area specified by the area positioning module; the numerical value sliding processing module is used for drawing a numerical value sliding map layer on a background map layer of each date or time subitem respectively; and the date and time adapter is used for providing and updating system date and time. The invention also discloses a method for realizing the stereoscopic rolling type date and time adjustment function in the embedded system. According to the technical scheme, less system operation resources is utilized, a stereoscopic rolling effect in the process of adjusting the date and time numerical value in the embedded system is achieved, and the system and the method are efficient and quick.

Description

Technical field [0001] The invention relates to an embedded system, in particular to an embedded system with a date and time adjustment function and an adjustment method thereof. Background technique [0002] As a human-computer interaction method, touch technology gives multimedia a new look with its simple, convenient and natural advantages. It is widely used in tablet computers, mobile phones, personal digital assistants (PDA), printer consoles, and digital photo frames. And other electronic products. In embedded systems such as this, providing date and time display services is a common and practical function, and the method of directly sliding the corresponding area on the touch screen to adjust the date and time values ​​is more and more accepted and loved by users. In order to enhance the user experience, some products have added a three-dimensional scrolling effect when adjusting the date and time values. However, the three-dimensional scrolling effect of such products ge...

Problems solved by technology

In such embedded systems, it is a common and practical function to provide date and time display services, and the method of directly sliding the corresponding area on the touch screen to adjust the date and time values ​​is more and more accepted and loved by users. In order to enhance the user experience, some products even add a three-dimensional scrolling effect when adjusting the date and time values. However, these products generally use the method of real-time rendering of the processor or graphics accelerator to achieve the three-dimensional scrolling effect. The disadvantage is that Occupies more operating resources of the processor and memory. In a lightweight system such as an embedded system, it is obviously unnecessary to invest too much system resources in a date and time display service that is practical but not the main function. waste
