摘要
单片机的多机串行通信应用十分广泛,当串行口被占用又要进行多机通信时就要采取一定措施。通过使用89C2051单片机接收各路串口传感器的数据,同时使用多路高精度ADC对转换成电压的温度等信号进行采样,可有效地解决系统的多机并行通信需求。
Multi-machine serial communication is applied in a wide range. It is necessary to take certain measures when multi-machine communication is done but the serial port is occupied. By using the 89C2051 microcontroller serial port to receive sensor data, and using multi-channel high-precision ADC to sample and convert temperature to voltage signal, multi-machine parallel communications are effectively performed.
