设计一个数据采集系统
基本要求：要求具有8路模拟输入
输入信号为0——500mV
采用数码管8位，显示十进制结果
输入量与显示误差<1%不要用单片机的，要用8255，8259

Through the agreement Modbus RTU mode of understanding the design of a wireless data acquisition system collected nodes, Acquisition nodes will receive temperature sensor output signal can receive, reply to wireless data acquisition controller information frame, Upload Real-time detection of temperature parameters; Wireless data communication interface used NRF2401. Four-channel detection. Information frame format used Modenbus agreement frame format. Designed with the main controller AT89C51 Digital Temperature Sensor, MAX7219 shows that using the chip
