Problems solved by technology

However, this invention implements left and right sliding and up and down sliding to switch user interfaces in the LVGL system framework, and cannot realize the circular sliding function of the interface, and the implementation method is too complicated. When the display effect needs to be modified, the entire program needs to be refreshed by updating the program , not only is inefficient, but also affects the service life of the flash

Embodiment 1

[0033] like figure 1 As shown, this embodiment provides a lvgl interface cyclic sliding method based on configuration, including a configuration process, a callback mechanism setting process, and an interface sliding processing process:

[0034] like figure 2 As shown, the configuration process includes: creating a tabview object on the current interface according to the requirements of the business process, including setting the size of the tabview (the size of the tabview is generally the screen size); creating at least one tab that needs to be displayed in the business process on the tabview object object, establish the index ID of the tab object, that is, TABID, set the maximum value MAX of TABID and the step value TAB_CNT; create an img object and a label text object to be displayed on each tab object, and determine the corresponding image information; close the tabview The sliding function of the object;

[0035] Among them, the step value TAB_CNT is usually set to 1,...

Embodiment 2

[0064] like Figure 7 As shown, in this embodiment, a configuration-based lvgl interface circular sliding device is provided, including:

[0065]The configuration module is used to create a tabview object on the current interface according to the requirements of the business process, including setting the size of the tabview (the size of the tabview is generally the screen size); creating at least one tab object that needs to be displayed in the business process on the tabview object, Establish the index ID of the tab object, namely TABID, set the maximum value MAX of the TABID and the step value TAB_CNT; create an img object and a label text object to be displayed on each tab object, and determine the corresponding image information; close the tabview object sliding function;

[0066] Among them, the step value TAB_CNT is usually set to 1, so that each interface can be displayed in sequence. If it is set to 2, the interface will be displayed in a jump; if it is set to 3, the...

Abstract

According to the configuration-based lvgl interface circular sliding method and device provided by the invention, the lvgl interface circular sliding can be realized based on the configuration of the user, the circular sliding of the lvgl interface can be realized, the sliding is more personalized, and the later modification of the display effect is simpler and more feasible. When the method is specifically applied, the program space can be subjected to partition management, and different partitions realize different functions, so that partition updating can be realized, the whole program space does not need to be erased and programmed, the efficiency is high, the refresh frequency of the flash can be effectively reduced, and the service life of the flash is prolonged.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for cyclic sliding of an lvgl interface based on configuration. Background technique [0002] At present, there are high-end and low-end gui interfaces of electronic devices in embedded systems. The high-end ones mainly include the android system framework and the linux qt framework; Linux GUI support system), touchgfx, ucwin, etc. Some require open source, some are only for individual chips, and the development efficiency without PC-side simulator is low. [0003] Lvgl (Light and VersatileGraphics Library, lightly integrated graphical interface library) is a new type of gui (Graphical User Interface, GUI for short, also known as graphical user interface), the number of codes is small and easy to port development, supports touch screen, using event callback It has a pc-side simulator, which can be developed under linux, mac, and windows systems, and can co...
