内部定时器与中断实验



由8051内部定时器0按方式1工作，即作为16位定时器使用，每0.1秒钟T0溢出中断一次。要求编写程序模拟循环彩灯。彩灯变化花样为：由中间（L4、L5）两位开始向两侧依次累加点亮；全亮后由中间（L4、L5）两位开始向两侧依次累加熄灭；全灭后由两边（L1、L8）两位向中间依次累加点亮；全亮后由两边（L1、L8）两位向中间依次累加熄灭。各时序间隔为0.5秒，依此循环。-Internal timer with the interruption of the experiment by the 8051 internal timer 0 by way of a work, that is used as a 16-bit timer, every 0.1 seconds a T0 overflow interrupt. Requested by the simulation cycle lantern. Lantern patterns change as follows: from the middle (L4, L5) followed by the two began to accumulate on both sides of light　by the middle of the whole-liang (L4, L5) followed by both sides of the two began to accumulate extinguished　body by both sides ( L1, L8) followed by two to the middle of cumulative lit　all-liang by both sides (L1, L8) followed by two to the middle of cumulative extinguished. The timing interval is 0.5 seconds, and so the cycle.
