carslight
- 输入信号:左转弯传感器LH,右转弯传感器RH和紧急制动或慢行传感器JMH,另外,汽车尾灯主要是给后面行使汽车的司机注意。为了使尾灯的光信号更明显,采用亮灭交替的闪烁信号,其闪烁周期为2秒,即尾灯亮1秒,灭1秒,再亮1秒…。在图9-21中设置了一个1秒时钟的输入信号CP。 输出信号:输出共设两个,左面一个尾灯,右面一个尾灯,既左转弯时指示灯LD和右转弯时指示灯RD。-input signal : LH sensor made a left turn, Peccant RH sens

watch
- 用VHDL设计实现秒表功能:秒表功能包括开始/暂停键和清零键,精度要达到0.01秒,所以计数显示共有八个数码管,而每个数码管又有八个管脚,因此采用扫描显示的方法,减少管脚数量。时钟脉冲由最低位给入,采用异步方式驱动更高位的计数,时钟频率应该为100Hz,通过数码管显示,共有八个数码管,所以扫描频率应在100Hz的8倍以上。(付按键消抖代码)-VHDL design with a stopwatch functions: stopwatch features include Start/PAUSE
