实验二 累加和串并行显示实验
一．实验目的：学习80C196KC单片机I/O和T2定时应用。
二．实验内容：将4000H首地址的16单元的内容累加，取结果的低4位在P1口并行显示5秒钟，“1”灯亮，“0”灯暗；然后再在P1.0串行输出结果先输出4位高位，后输出4位低位。“1”灯亮，“0”灯暗，每位持续时间两秒。
三．实验预备知识：采用T2内部定时功能。相关中断屏蔽，IOC控制寄存器，中断允许，中断向量，中断程序格式。（80c196kc，晶振频率6Mhz）
四．实验步骤：P1.0…P1.3对应接L0…L3。先在4000H首地址的16单元内任意键入数据后，运行程序，灯亮后观察结果。-Experiment II cumulative serial and parallel display experiment. Purpose: the learning 80C196KC MCU I/O and T2 timing applications. II. Low 4 Experiment: 4000H first address of a 16-unit accumulation, whichever results in the P1 port parallel display 5 seconds, then lights " 1" , " 0" lights dark P1.0 serial output results The first output 4 high after output 4 low. Lights " 1" , " 0" lights dark, each duration is 2. III. Experimental Preliminaries: T2 internal timing function. Related interrupt mask, IOC control registers, interrupt enable, interrupt vector, interrupt program format. (80c196kc, the crystal frequency 6Mhz) four. Experimental steps: P1.0 ... P1.3 corresponding pick L0 ... L3. After the first 16 units within the 4000H first address any type of data, run the program, the lights and observe the results.
