Abstract: This article discusses the design and implementation of keyboard device driver based on embedded Linux and Qt/Embedded. Based on the working process and keyboard driver characteristics, the article divides the keyboard driver into two modules: bottom device driver module and upper text input module.

Key words: Embedded device, Linux, Qt/embedded, Keyboard driver, Text input
