对单片机C语言教材中一段程序的分析
<p>C语言是一种结构化的高级语言,具有代码紧凑、可移植性强、符合人的日常思维方式等特点.由于不需要深入了解单片机的指令系统和硬件结构、上手容易等特点,单片机的C语言学习和应用变得很普及.一些单片机开发者由于不了解单片机C语言和通用计算机C语言之间的区别,当涉及单片机内部硬件及端口操作,特别是在单片机的应用中经常使用的位操作等,编程时经常出现一些不易发现的错误.本文通过对一段程序的分析,从语法错误
基于STM32单片机的嵌入式语音识别系统设计
<p>设计了一款以STM32F103为核心的自然语言识别系统,为满足实时语音识别系统对内存资源和运算速度的要求,基于硬件资源合理设计语音处理算法,在嵌入式平台上实现了对孤立词语的语音识别。首先根据背景噪声和语音信号的时域特征差异设定相应门限值,从而实现了对语音信号的端点检测。然后针对语音识别中传统梅尔倒谱系数对语音的高频信息敏感度较低,对语音信号分别提取梅尔倒谱系数(MFCC)与翻转梅尔倒谱系数(
基于AT89C51的简易电子琴设计与实现
<p>随着计算机和通信技术的发展,电子琴等娱乐乐器走入千家万户。本系统采用STC89C51单片机,设计矩阵式键盘模块、LED显示管模块、扬声器模块、主程序部分、显示程序部分、按键检测部分等模块。经系统仿真,实现了16个独立按键分别代表16个不同的音符,有高有低等功能。本设计电路耦合性好,易操作,成本低,实用性强,便于携带。</p><p>With the development of compute
基于MCU技术的GPS定位设计与应用研究
