[DSP program] traffic_lights DL : 0: 本系统采用MSC-51系列单片机ATSC51和可编程并行I/O接口芯片8255A为中心器件来设计交通灯控制器，实现了能根据实际车流量通过8051芯片的P1口设置红、绿灯燃亮时间的功能；红绿灯循环点亮，倒计时剩5秒时黄灯闪烁警示（交通灯信号通过PA口输出，显示时间直接通过8255的PC口输出至双位数码管）；车辆闯红灯报警；绿灯时间可检测车流量并可通过双位数码管显示。-The system uses MSC-51 series single-chip ATSC51 and programmable parallel I/O interface chip 8255A-centric device designed to control traffic lights, can be achieved in accordance with the actual traffic flow through the P1 port 8051 chip set red, green fuel Liang function of time traffic light cycle, the countdown five seconds left when the yellow light flashing warning (traffic lights through the PA output signal indicates the time directly through the PC port output 8255 to double-digits) vehicle alarm闯红灯 green time traffic flow can be detected through a double-digital display.

[DSP program] Intersection-traffic-signal-control DL : 0: 设计一个紧急控制开关信号，当紧急开关信号为1时，两个方向的灯全为红灯。紧急开关撤消后，按照开关按下之前的状态继续运行（其参数要保存）。（2）设计一个夜间行车开关，当开关按下后，两个方向都只有黄灯闪烁，其它灯熄灭。（3）设计两个方向的亮时时间可调。-Design an emergency control switch signal, when the emergency switch signal is 1, the two directions of light are all red. After withdrawal of the emergency switch, according to the state before the switch is pressed to continue to run (the parameters to be saved). (2) to design a switch driving at night, when the switch is pressed, the flashing yellow light are only two directions, the other lights off. (3) design time in both directions when the light adjustable.

[DSP program] Lab0601-PID DL : 0: 用dsp实现交通灯综合控制，交通灯分红黄绿三色，东、南、西、北各一组，用灯光信号实现对交通的控制：绿灯信号表示通行，黄灯表示警告，红灯禁止通行，灯光闪烁表示信号即将改变。 - 计时显示：8×8 点阵显示两位计数，为倒计时，每秒改变计数显示。 - 正常交通控制信号顺序：正常交通灯信号自动变换： ⑴ 南北方向绿灯，东西红灯(20 秒)。 ⑵ 南北方向绿灯闪烁。 ⑶ 南北方向黄灯。 ⑷ 南北方向红灯，东西方向黄灯。 ⑸ 东西方向绿灯(20 秒)。 ⑹ 东西方向绿灯闪烁。 ⑺ 东西方向黄灯。 ⑻ 返回⑴循环控制-Dsp to achieve comprehensive control of traffic lights, traffic lights dividends yellow-green color, East, South, West, North, a group, use the traffic control light signal: green signal Said passage, yellow indicates a warning, red closed to traffic, lights flashing signal is about to change. - Timing: 8 × 8 dot matrix display two counts, as the countdown, the second change the count display. - Normal traffic control signals sequence: automatic transformation of the normal traffic signal: The ⑴ north-south direction of the green light, what a red light (20 seconds). (2) north-south direction the green light flashes. (3) north-south direction yellow. (4) north-south direction red light, yellow light east-west direction. ⑸ east-west direction the green light (20 seconds). ⑹ east-west direction the green light flashes. ⑺ east-west direction yellow. ⑻ return (1) loop control
