PROFIBUSDP
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.)

基于单片机的电子秤设计
开机自检、去皮、计价、清零、中文液晶显示等；
从上述中可以看出，本设计的主要思路是利用压力传感器得到重量的变化并且将重量的变化经过电压放大电路经过，A/D转换器将模拟量变换为数字量，单片机可以顺利的读取，并且将得到的信息进行采集后计算。通过累加之后的方式将物品的重量和价值总额，通过显示电路显示出来(Self-check, peel, price, clear, Chinese liquid crystal display and so on;
It can be seen from the above, the main idea of this design is the change of the pressure sensors are used to get the weight and the weight change after the voltage amplification circuit, A/D converter analog conversion into digital quantity, single chip can be read smoothly, and to get information from the acquisition after calculation. The weight and total value of the item are displayed by means of the display circuit.)
