具有8位开关量输入，8位开关量输出(或带有四位数码显示输出)，并具有8路AD输入（ADC0809）,1路DA输出（DCA0832）的单片机控制系统。系统要求对8位开关量输入信号能够进行监控，8位开关量输出对应8位开关量输入(或用数码显示出来)。对于模拟量输入、输出通道（A/D,D/A），要求编制比例K放大器输出-Switch with 8 input, 8 output switches (or with four digital display output), and 8 with AD input (ADC0809), 1 Road DA output (DCA0832) of single-chip control system. System requirements for the 8-bit input signal to switch monitor output 8-bit switch 8 switches the volume of the corresponding input (or digital display). For analog input and output channels (A/D, D/A), called for the ratio of the output amplifier K
