用电脑串口控制单片机流水灯状态,用电脑串口控制单片机流水灯状态(Serial control with a computer chip light water status)

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.)
