12C5A60S2EEPROM

通讯程序，利用的是rs485协议,调试运行可以通过，本人实验过的(This programme is used for the commucation of pc and avr)

C语言编程，4X4键盘扫描程序，可以直接使用到51单片机中(C language programming, 4X4 keyboard scanner can be used directly in the 51 SCM)

AD5933评估板下位机程序（keil C）和上位机程序（VB）(AD5933 Evaluation procedures under the plan (keil C) and PC (VB))

一个C++库，用于CNC数控加工之CAM处理。(OpenCAMLib (ocl) is a c++ library for creating toolpaths for cnc-machines such as mills and lathes.)

使用VB与PIC采集,采用软件中断方式，使用研华1710集成卡。(Using VB with PIC acquisition, the software interrupt, use the the Advantech 1710 integrated card.)

ISL94212单芯片应用代码，包括读取12串单体电池电压，温度，均衡功能，本例以s12单片机为例(ISL94212 single-chip application code, including reading the 12 series of single cell voltage, temperature, balance function, in this case in order to s12 microcontrollers, for example)

可以产生幅度、频率可调的方波，频率50hz到1M(Can produce the amplitude, frequency adjustable Fang Bo, frequency of 50Hz to 1M)

基于AT89S52单片机的超声波测距系统设计源代码(Ultrasonic ranging system based on single chip design based on Ultrasonic Ranging System source code source code source code of ultrasonic ranging system based on single chip design)

说明：  本PDF文件为市电电压频率测量计的设计说明书！从中能了解相关的电路设计(The PDF file is mains voltage frequency meter design manual! From which to understand the relevant circuit design)

在stc51单片机上，timer0、timer1、timer2的控制(In the stc51 microcontroller, timer0, Timer1, timer2 control)
