1-wire"从机"模拟程序, 不是主机,1-wire的主机模拟程序网上很多.使用mega88模拟DS1990A芯片时序, 再加上模拟主机就可以搭建不使用DALASI芯片而使用1-wire协议的系统.编译IAR for AVR 4.20.(1-wire )

STC15F60S2单片机的数据手册，内含典型应用电路，驱动程序(STC15F60S2 MCU datasheet, containing the typical circuit , driver program)

stm32的usart1和usart3配置为串口通信，均用中断实现串口接收。(stm32 usart1 and usart3 configured for serial communication, both with the serial port receive interrupt achieve.)

数据采集器录入，采集，安装调试。下载同步功能，是初学者的好例子(dada collection)

An exception that indicates that garbage-collector is finalizing a database object that is not explicitly closed.

电力线载波模块资料，适用于电力线载波开发，(Power Line Carrier Module)

增量pid的阶跃跟踪程序，适用于执行机构是控制量的增量的场合(Pid incremental step tracking procedure is applied to the implementation of the incremental volume control occasion)

气源环境监控系统设计与实现Air Supply Design and implementation of environmental monitoring system(Air Supply Design and implementation of environmental monitoring system)

说明：  内有PID源码驱动，包含位置式PID和增量式PID。PID通过结构体定义，可同时定义多套参数，并同时使用，并不会相互影响。(There is a PID source driver, including position PID and incremental PID.PID through the structure definition, can be defined at the same time multiple sets of parameters, and use at the same time, will not affect each other.)

1.由上位机发送1给单片机时，蜂鸣器以400ms频率发声，发2时以200ms频率发声，发3时以100ms频率发声，发4时关闲蜂鸣器。 1.以2400bps从计算机发送任一字节数据，当单片机收到该数据后，在此数据前加上一序号然后连同此数据一起发送至计算机，当序号超过255时归零。 2.以16进制发送一个0-65536之间的任一数，当单片机收到后在数码管上动态显示出来，波特率自定。 3. 用AD以1HZ的频率采集模拟信号，然后转换成数字量，再将其以1200bps发送到计算机，在计算机上显示。 4.按下矩阵键盘第一行时以1200bps发送，1，2，3，4，第二行时以2400bps发送5，6，7，8，第三行以4800bps发送，9，10，11，12，第四行以9600pbs 发送，13，14，15，16. (1. From the PC to send a single chip, the buzzer to 400ms frequency of sound, made 2 to 200ms frequency sound, made from 3 to 100ms frequency sound, made 4 free buzzer off. 1. To 2400bps from the computer to send any byte of data, when the microcontroller receives the data in this data with a serial number before then sent along with the data to the computer, the serial numbers when more than 255 zero. 2. To send a 16-hexadecimal any number between 0-65536, when the microcontroller in the digital receipt is displayed on a dynamic, custom baud rate. 3. 1HZ with the frequency of AD in order to capture analog signals, then converted to digital, and then send it to 1200bps to the computer, the computer display. 4. Press to 1200bps matrix keyboard to send the first row, 1,2,3,4, 5,6,7,8 the second row to 2400bps send the third line to 4800bps send, 9,10,11,12 , the fourth line to 9600pbs send, 13,14,15,16. )
