Abstract

The invention relates to an embedded LED display controller. The embedded LED display controller comprises a master control module, and a display data output module, a volatile memory, a nonvolatile memory and a video input interface circuit module that are electrically connected to the master control module. The master control module is used for responding to a mode switch control signal produced by triggering conducted by a user to enable the embedded LED display controller to function in a synchronous mode or an asynchronous mode in a switched manner, so that when the embedded LED display controller functions in a synchronous mode, the master control module obtains, via the video input interface circuit module, video data from an external video source, processes the data and then outputs the data through the display data output module, and when the embedded LED display controller functions in as asynchronous mode, the master control module obtains video data from an internal video source, processes the data and then outputs the data through the display data output module. Therefore, the embedded LED display controller can be switched between a synchronous mode and an asynchronous mode, meets the intelligence requirement for users, and exhibits great user experience.

Description

technical field [0001] The invention belongs to the technical field of LED display control, in particular to an embedded LED display controller. Background technique [0002] Embedded operating system is a system software with a wide range of uses, usually including hardware-related underlying driver software, system kernel, device driver interface, communication protocol, graphical interface, standardized browser, etc. The embedded operating system is responsible for the allocation of all software and hardware resources of the embedded system, task scheduling, control, and coordination of concurrent activities; it must reflect the characteristics of the system where it is located, and can achieve the functions required by the system by loading and unloading certain modules. At present, the operating systems widely used in the field of embedded systems include: embedded Linux, Windows Embedded (such as WinCE6.0), VxWorks, etc., as well as Android and iOS used in smart phones...
