多种实时时钟芯片的读写应用程序，所用控制器为MCS

这是一个本人编写的程序，单片机89C52，主要是通过计量芯片ATT7028测量输入端的电压电流及电压电流间的各个夹角值，比较有用-This is the one I prepared procedures, 89C52 microcontroller, mainly through measuring chip ATT7028 measuring the input voltage and current, voltage and the current value of various angles, more useful

2048点FFT在TMS320C240x定点DSP上的实现2048点FFT在TMS320C240x定点DSP上的实现-2048-point FFT in TMS320C240x fixed-point DSP to achieve the 2,048 points FF T in TMS320C240x fixed-point DSP Implementation

用单片机配置FPGA，英文，不用说了吧，呵呵，快下吧-MCU FPGA configuration, English, needless to say, all right, what are you fast

头件的中的#ifndef，这是一个很关键的东西。比如你有两个C文件，这两个C文件都include了同一个头文件。而编译时，这两个C文件要一同编译成一个可运行文件，于是问题来了-The first pieces of# Ifndef, this is a very key things. For example, you have two C file, the two C files include the same file size. And compile-time, the two C files to compile together into a run file, then issue the

仪器仪表键盘显示模拟系统，用AT89S52芯片作为系统的CPU，控制系统的按键及显示器部分。用8路同相三态双向总线收发器74LS245芯片驱动LED。4X4矩阵键盘作为系统人机交互的重要部分，用于向单片机应用系统输入数据或控制信息，设计4X4矩阵键盘分别对应键码“0-F”。系统可以实现的基本功能包括开机LCD液晶屏幕显示“大专05电子信息X班XXX毕业设计”信息；按下任意一个按键，LCD液晶屏幕显示相应按键的信息。在基本功能的基础上还增加了一个扩展功能，即增加一个LED数码管同步显示相应键码-Show the simulated keyboard instrumentation systems, using AT89S52 chip as a system CPU, system control buttons and display parts. With 8-phase three-state bidirectional bus transceiver 74LS245 chip-driven LED. 4X4 matrix keyboard system as an important part of human-computer interaction, single-chip microcomputer application system used to input data or control information, the design of 4X4 matrix keyboard key code corresponding to

单片机最小系统，两位LED数码管由串口输出接两个164驱动，Lout,Rout为左右声道输出，SET， ALT0， ALT1为三个按键，也可自己在开始的I/O定义改成你想用的I/O口；12M晶振若用89C51则只可装下约14首歌曲，用89C52则可装下近40曲-smallest SCM system, two LED digital serial output from the pipe then two 164-driven, Lout, Rout for about channel output, SET, ALT0, ALT1 to three keys, but also his own in the beginning I/O definition you want to change the I/O port; If using crystal 12M 89C51 can carry only about 14 songs, can be loaded with 89C52 Near 40
