这里设计是以 C8051F020单片机最小系统为核心,将采集到的波形信号通过 C8051F020集成的模数转换(A/D)、数模转换(D/A)完成相应的信号转换,并将波形信号存储于外接的MB85RS256存储器中,实现波形采集、存储和回放的功能.同时,系统外扩(LCD,Liquid Crystal Display),在 LCD 上显示波形信号的周期和峰峰值.该系统能够同时采集两路信号波形,并按先后顺序存储在存储器中,读取存储器实现两路信号波形的回放功能.实验结果表明,该系统能够实现相应的功能,性能安全,可靠.

@@@@The design, based on C8051F020 Microcontroller Unit (MCU) minimum system, realizes waveform acquisition, storage and playback functions, and through MCU, implements A/D and D/A, and then stores the waveform in the external MB85RS256 memory. Meanwhile LCD extended by the system displays the waveform signal period and peak-peak value. The system could also capture two-way signal waveform and realize the corresponding acquisition storage and playback functions of the signal. The experiment indicates that this system could fulfil the responding functions, and is safe and reliable in performance.
