基于 飞思卡尔单片机 MODBUS汇编源程序 可以-FREESCALE

本程序是用于高速冲床上的送料控制程序，一个较为简单的89C51中断、定时计数器应用程序，已经调试成功，今天为大家出点力，也希望能在以后的学习中能得到大家的帮助。-This procedure is used for high-speed red bed feed control procedures, a relatively simple 89C51 interrupt, timer counter application has debugging success for the U.S. today, a little effort, but also hope to study in the future everyone will be help.

这是这几天我用C做的一个高性能计时器.希望大家指教-This is the last few days I used to do a high-performance C timer. Hope everyone advice

1) 东西方向车辆放行20秒钟。即东西方向的绿灯和南北方向的红灯同时点亮20秒钟； 2) 20秒钟后，东西方向的黄灯闪烁2秒钟，以警示车辆将切换红绿灯。此时南北方向仍维持红灯点亮。在南北方向亮红灯期间，在2位数码管上显示计数值（每秒减1），从20减至01。 3) 东西方向的黄灯闪烁2秒钟后，转为南北方向放行20秒钟。即东西方向的红灯和南北方向的绿灯同时点亮20秒钟； 4) 南北方向放行20秒钟后，转为南北方向的黄灯闪烁2秒钟，以警示将切换红绿灯。此时东西方向仍维持红灯点亮。 5) 南北方向的黄灯闪烁2秒钟后，再转为东西方向车辆放行20秒钟。如此循环重复。 -1) direction vehicle release 20 seconds. What is the direction of red and green light at 20 seconds, 2) 20 seconds later, the yellow lights flashing warning vehicles with 2 seconds, switch to the traffic lights. This is still remain red light north-south direction. In the south during the red light, in the direction of the digital display tube of 2 per plan (minus 1), from 20 to 2001. 3) the yellow lights flashing direction to 2 seconds later, the south direction release 20 seconds. What is the direction of the north-south direction of red and green and light 20 seconds, 4) north-south direction after 20 seconds to release the north-south direction, yellow lights flashing warning, with 2 secon
