P1.7～P1.0接发光二极管L8～L1，要求利用单片机内部定时器1，按方式1工作，每0.01秒T1溢出中断一次。要求编写程序模拟时序控制装置。开机第1秒钟L1、L3亮，第2秒钟L2、L4亮，第3秒钟L5、L7亮，第4秒钟L6、L8亮，第5秒钟L1、L3、L5、L7亮，第6秒钟L2、L4、L6、L8亮，第7秒钟8个发光二极管全亮，……一直循环下去。fosc=11.0592MHz-P1.7- P1.0 then LED L1 to L8, by using a timer internal microcontroller, a work by the way, every 0.01 seconds T1 interrupted an overflow. Simulation prepared timing control device. Boot 1 seconds L1, L3- liang, two seconds L2- L4, L5 three seconds, L7- liang, 4 seconds L6, L8-liang, 5 seconds L1, L2, L5, L7- liang, 6 seconds L2, L4, L6, L8- , 7 seconds 8-LED whole ... has been the cycle continues. 11.0592MHz fosc =
