能够测量0hz~1Mhz范围内的各种频率，有自动换档功能-0hz ~ 1Mhz to measure the scope of the various frequencies, and features automatic transmission

MMX即多媒体可扩展指令集，通常用汇编编写，内嵌于C++或C，提升图象算法的执行速度。该文档介绍了MMX的指令集及编程规范。-That is scalable MMX multimedia instruction set, often used to prepare a compilation, embedded in C++ Or C, to enhance the implementation of the speed of the image algorithm. The document describes the MMX instruction set and programming norms.

调试通过了的基于89S51的LCD12864液晶显示-Debugging based on the adoption of the 89S51 LCD LCD12864

此程序完成功200HZ的固定频率,稳定性很高,波形失真度小,如果要想产生固定频率,这个程序是最好的选择!-success of this procedure 200Hz End of fixed-frequency, high stability, waveform distortion small, if they have a fixed-frequency, the procedure is the best choice!

本程序实现系统时间查看.-system to examine.

24C02存储IC有2K的空间,可用于断电后程序的保存,这里提供读写程序-24C02 memory IC has 2K of space, can be used to save power after the procedure, here to read and write procedures

与java相关的各种例程 不是很难 适合初学者 上手比较容易-And java-related routines are not difficult to get started is easier for beginners

资源描述EV1527解码程序:单片机PIC16F630,内部4MHz,EV1527发射频率433MHz,振荡电阻270K,遥控器供电电压DC12V,周期为1.2ms。 在上电3S钟内按开机键，程序学习遥控器识别码，1次只能学习一个遥控器；按关机键程序将擦除所有遥控器识别码。 本程序最多可以学习42个遥控器，当遥控器个数满42个后第43个将会覆盖第1个。

该课程设计使用了三块接口芯片，8253、8255、8259；在程序中需要对8255芯片的控制口进行修改，改成自己所用实验板的端口-The course is designed to use the three interface chip, 8253,8255,8259 in the program need to control the port 8255 to modify the chip, into his own experimental port board
