pic18f458单片机 io口是如何工作的

一个基于嵌入式linux的串口驱动程序和测试程序的源码，很实用的。-a Linux-based embedded serial port driver and testing procedures source code, the very practical.

嵌入式界面 菜单移植  STM32上移植的ucgui  ,方便菜单编写，字库随意更改；可以先用VC在PC机上进行模拟测试。

利用8051的定时器用来计数作为频率计的基础。测频范围是1--10000HZ-The use of 8051 timer used to count as the basis of frequency. Measuring frequency range is 1 10000HZ

本设计的基本要求是以复杂可编程逻辑器件CPLD为基础，通过在EDA系统软件ispDesignExpert System 环境下进行数字系统设计，熟练掌握该环境下的功能仿真，时间仿真，管脚锁定和芯片下载。 本系统基本上比较全面的模拟了计数式数字频率计，广泛应用于工业、民用等各个领域，具有一定的开发价值。- This design basic request is take complex programmable logical component CPLD as a foundation, through environment carries on the number system design in EDA system software ispDesignExpert under the System, skilled grasps under this environment the function simulation, the time simulation, base pin locking and chip downloading. This system basically quite comprehensive simulation has counted the numerical expression numeral frequency meter, widely applies to the industry, civilly and so on each domain, has the certain development value.
