本程序在利用TMS320VC5402定时器0中断的基础上,拓展到模拟交通灯--东西两方 的红、绿、黄灯有次序的交叉点亮.本程序是用C语言代码编写的,在CCS环境下调试通过,并在其实验箱上运行成功.-Procedures in the use of the timer 0 interrupt TMS320VC5402 on the basis of the simulation was extended to traffic lights- something the two sides of the red, green and yellow are the order of the cross-light. This procedure is the preparation of C language code, and the environment in the CCS adopted under the debugger, and in its box to run a successful experiment.
