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.
