T9输入法在嵌入式设备中的实现方案

Implementation of T9 Input Method in Embedded Device

文字输入是人机交互的基本方式,而中文输入法在其中占有重要地位。本文基于资源有限的STM32嵌入式开发环境和T9输入法基本原理设计了一种中英文输入法的实现方案。通过对程序和码表的设计,结合键盘和TFT显示屏的数字串输入,可以对目标文字进行查找和锁定,从而实现了中、英文的输入功能。

Text input is the basic way of human-computer interaction,and Chinese input method plays an important role.In this paper,a solution of English and Chinese input method is designed based on the embedded development environment of STM32 with limited re-sources and the basic principle of T9 input method.Through the designs of the procedures and codes,combining the digital string input of keyboard and TFT display,the searching and locking for target text is achieved,so that the input function of English and Chinese is realized.
