C8051F040 T4 capture measured pulse frequency square

读取一个电机码盘信号，里面有对串口读写，对控制寄存器读写的代码。入门级！-read a motor encoder signals, and they read and write to serial port, the control register read and write code. Entry-level!

十分详尽的串口调试程序，未经测试，不过已通过仿真-Very detailed serial debugger, without testing, but had passed through Simulation

51单片机虚拟I2C协议、组合式按键、串口通信的简单综合应用，配Proteus仿真电路-51 Single-chip virtual I2C agreement, the modular keypad, serial communications, a simple integrated application, with Proteus simulation circuit

at89s51的中文资料，方便单片机初学者学习参考，并且翻译质量基本上可以。-English at89s51 of information for beginners to study single-chip reference, and basically the quality of translation.

基于等精度测频原理，设计的等精度频率计，测试结果很精确，达到0.01HZ。-Such as the accuracy of frequency measurement based on the principle of design, such as precision frequency meter, test results are accurate to 0.01HZ.

电压显示 proteus仿真,keil编写程序-Proteus simulation voltage display, keil programming

这是一个结合Proteus和51单片机实现的一个按键加速实例。以验证-This is a combination of Proteus and 51 of the MCU examples of a button to accelerate. To verify
