单片机和ADC0832的AD模数转换,在工业控制和智能化仪表中，通常由微型计算机进行实时控制及实时数据处理。计算机所加工的信息总是数字量，而被控制或被测量的有关参量往往是连续变化的模拟量，如温度、速度、压力等等，与此对应的电信号是模拟信号。-Microcontroller and ADC ADC0832 of AD, in the industrial control, and intelligent instruments, usually in real time by a micro-computer control and real-time data processing. Computer processing of information is always digital, and be controlled or measured parameters are often related to continuously varying analog, such as temperature, velocity, pressure, etc., and the corresponding electrical signals are analog signals.
