【摘要】 传统单片机实验装置现场手工转接线存在接触不良,提出了利用上位机根据实验内容通过电子式交叉开关自动转接线,节约了实验教学时间,提高了实验可靠性和实验效率。具体描述了该实验系统的设计思路,给出设计思路的流程框图。使用ADI公司的高新能模拟开关阵列ADG1611芯片和赛灵思公司(Xilinx Inc)的FPGA芯片XC3S1200E,并配合设计作为控制部件,给出了实现现场自动转接线的局部设计电路图。更多还原

【Abstract】 Since the traditional MCU experimental device manual wiring on spot has poor contact,a scheme of the automatic wiring controlled by PC and electronic crossover switch according to the experiment content is proposed. With the system,the experimental teaching time was saved,and the experimental reliability and efficiency were improved. The design idea of the experimental system is described in detail. A flow chart of the design idea is offered. The control unit with ADI’s high-performance analog switch array chip ADG1611 and Xilinx’s FPGA chip XC3S1200E is designed. The circuit diagram of realizing the automatic wiring system is given in this paper.更多还原
