说明：  设计一个基于单片机数据采集与双机通信系统。利用单片机的串行口与扩展的A/D接口，进行数据采集、标度变换与通信，实现2台单片机之间的双机数据通信与显示。 功能要求： ①．A/D采样数据，将采样数据发送另一台单片机。 ②．接收发送的采样数据，并用两台单片机的LED或LCD显示采样实时数据。 ③．发送数据控制对方的某一对象，如：直流电机、发光二极管等。 硬件设计： 设计相应的A/D、显示、串行通信接口的电路，利用单片机的串行口与扩展的A/D接口，实现2台8031单片机之间的双机数据通信与显示。
(Design a single chip data acquisition and communication system based on two planes. The use of MCU and serial port expansion A/D interface, data acquisition, communication with the scale transformation, to achieve double data communication with the display two microcontrollers. Functional requirements: ①. A/D sampling data, the sampling data is sent to another microcontroller. ②. Received samples of data transmitted, and with two single-chip LED or LCD display real-time data sampling. ③. Transmission data control each other an object, such as: DC motor, light-emitting diodes. hardware design: Design appropriate A/D, display, serial communication interface circuit, the use of single-chip serial port and expansion of A/D interface, dual-data communication between two 8031 display.)
