说明：  基于MSP430F149单片机串口16进制发送0-65536之间任意数字，然后用数码管动态显示(MSP430F149 microcontroller serial based 16-band transmit any number between 0-65536, and then use digital dynamic display)

利用单片机软件编写PRO兀BUS—DP从站协议，并改进PROFIBUS．DP从站驱动电路实现了PROFIBUS— DP的从站功能，取代了西门子公司的专用协议芯片SPC3。给出了PROFIBUS．DP从站硬件电路图和PROFI— BUS·DP从站软件程序流程图，由CP56ll和PC机构成主站与从站组成了通讯系统。分步骤详述了系统调试过 程。该方法可以降低系统成本、提高设计的灵活性并解决协议芯片来源单一导致的产品受限问题。(Microcomputer software development using PRO Wu BUS-DP slave protocol, and to improve the PROFIBUS. DP slave drive circuit of the PROFIBUS-DP functions from the station, replacing the company' s special protocol chip Siemens SPC3. Given PROFIBUS. DP slave hardware circuit and the PROFI-BUS · DP slave software program flow chart, the CP56ll and PC bodies into the main station and from stations of the communication system. System debugging process step by step details. This method can reduce the system cost, increase design flexibility and resolve protocol chip products resulting from limited sources of a single issue.)

介绍如何简单可靠而方便测量 4～20mA 信号的文章。许多仪器仪表在远距离传送信号时，都有可能采取 4～20mA 的方式进行传送。本文对使用运算放大器或者不用运算放大器的场合都有介绍。给出了接口电阻的计算方法以及调整4mA＝零点，20mA＝满度的详细说明。并附有局部连接的原理图。(How simple, reliable and convenient measurement of 4 ~ 20mA signal article. Many instruments in the long-distance signal transmission, may take 4 ~ 20mA way transmission. In this paper, an operational amplifier or op amp do not have a description occasions. Shows the calculation of the interface resistance and adjust the 4mA = zero, 20mA = full scale details. Local connections together with the schematic.)
