Design and implementation of graphical interface of vehicle display and control system based on SylixOS

Abstract

Abstract To satisfy the design requirements of the current vehicle display and control system, and in consideration of the independent controllable requirements of the current software and hardware platforms, this paper proposed a set of nationalized solution. The Loongson 2K1000 was selected as the main control chip, and the interface design and development of vehicle display control system was completed based on the SylixOS autonomous real-time operating system. This paper elaborated on the development process of the open source graphics library Qt, and proposed solutions to the screen flicker problem encountered during the development process.
