液晶显示程序，和51是负的，然后到液晶，然后一个很好的地方去。

基于单片机的数字频率计设计，定时器T0完成定时功能，T1采用计数功能-MCU-based design of digital frequency meter, timer T0 timing finish, T1 using count function

一种比较好用得PWM控制芯片，希望对您有所帮助。-Was a relatively easy to use PWM control chip, want to help you.

PID是控制智能小车的经典算法在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。它具有原理简单，易于实现，适用面广，控制参数相互独立，参数的选定比较简单等优点；而且在理论上可以证明，对于过程控制的典型对象──“一阶滞后＋纯滞后”与“二阶滞后＋纯滞后”的控制对象，PID控制器是一种最优控制-PID control of the smart car is the classic algorithm in process control, according to the percentage of deviation (P), Integral (I) and differential (D) control of PID controller (also known as PID regulators) is the most widely used as a automatic controller. It has simple, easy to realize, the application of a wide range of control parameters are independent of each other, the selection of relatively simple parameters, etc. and in theory can be proved that for a typical process control objects ─ ─

本程序是功能是实现51单片机与PC机之间的通信，程序简单-this is to tell how to use 51 single chip controler to communicate with pc

GCC的SD卡完整程序！可根据自己需要更改！-GCC complete the procedure of SD card! May need to change according to their own!

基于MCS- 51 单片机的洗衣控制系统, 控制面板由按键、指示灯和LED 显示器组成。 按键选择洗衣机工作方式, 指示灯配合按键工作, LED 显示器则显示洗衣机洗涤和脱水时 间。洗衣机的整体电路模块包括键盘矩阵、指示灯、电动机控制及电源电路。控制程序设计 包括定时中断服务程序、外中断服务程序及主程序。-Based on MCS-51 SCM laundry control system, control panel by the button, LED indicator light and display components. Button to choose washing machines work, light work with the button, LED display shows time washing machine washing and dehydration. Washing the overall circuit module includes a keyboard matrix, light, motor control and power circuit. Control program design includes interrupt service routine from time to time, outside the interrupt service routine and the main program.

使用89S52芯片来驱动1602液晶显示,用KEILC51编译,可靠,并实践过.-err
