用ADC0832采集两路电压数值，用DS12C887作为时钟芯片，用四线驱动的方式驱动1602液晶作为电压值和时间的外显设备。外设数个按键，可以作为数据采集键使用，用24C02作为存储芯片，采用总线协议进行数据的写入与读出。可通过外设键盘对历史数据查阅，按键误操作时能在1602上提示。数据采集要求出现上升或下降沿，直接显示高低电平差值，采集数据时先按下刷新键才能采集。动态刷新时系那是的数据为实际值而非差值，可作为电压表使用-ADC0832 collected two voltage values, DS12C887 clock chip, four-wire driven Driver 1602 as a voltage value and time explicit device. Peripheral keys, can be used as a data acquisition key 24C02 as a memory chip, using the bus protocol for the data writing and readout. Historical data access via a peripheral keyboard keys misuse in 1602 prompted. The data acquisition requirements of to appear the the rising or falling edge, and directly display when the first press the the refresh key in order to acquisition in the the difference between the high and low level, acquisition data. Dynamic refresh the Department of that when the is of the data for the the the difference between the the actual value rather than, can be used as the the the the use of of the voltage meter
