自动交通管理系统 用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁止线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示） 同时用2位数码管进行30秒钟递减时间显示。-automatic traffic management system using red, green, yellow a total of three light-emitting diodes, said two traffic lights, using SCM time simulation shows the regular traffic signal control. Signal changes in the law to be as follows : 1) Release Line : green clearance 25 seconds, bright yellow warning five seconds, and then the red-ban. 2) prohibit the lines : red-Ban 30 seconds, then green clearance. 3) When the red light in one direction- that if the direction of a car passed, the use of loudspeakers sound alarm. (Red light signals can hit 3- 5V analog said), while using two digital tube for 30 seconds decreasing time displayed.

small rtos for avr small rtos 使用了动态堆栈 想无需任何改动就可以编译这个程序，就必须安装winavr20050214和uv2,先点击uv2的工程文件打开这个工程然后在Tools---->Customize Tools Menu...嵌入gcc编译命令make all和make clean即可立即编译。编译后可以使用avr studio进行代码级仿真-small Byelorussian for avr small Byelorussian use of dynamic stack without any changes to be compiled for the process, it must be installed and uv2 winavr20050214, first click uv2 works documents before the project opened in Tools- gt; Customize Tools Menu ... embedded gcc compiler make all orders and instantly make clean compile. Compiled avr studio can be used for code-level simulation
