Design of Virtual Instrument Interface Based on Embedded Linux+QT

Abstract

This paper mainly summarizes the technical scheme of replacing traditional pointer automotive instrument with full liquid crystal by choosing hardware platform and software platform. Emphasis is laid on the application of QT graphical development environment in embedded Linux operating system. The full liquid crystal can solve the display and instruction of various monitoring information on automotive instrument. Qt Quick tool is used in the dynamic pointer design of full liquid crystal instrument, and how to use QML (descriptive scripting language) and C++ language mixed programming technology. A practical and mature instrument system can be designed for users, and a set of reasonable construction ideas and methods can be provided.
