定时器中断实验代码， 定时器3进行0.1秒定时，每0.5秒改变一次P2,P3口的值以产生走马灯效果。-timer interruption experimental code, three timers for 0.1 seconds regularly, every 0.5 seconds to change a P2, P3 to the values I have merry-go-round effect.

本系统利用凌阳SPCE061A单片机原理，设计了一种双向超声测距系统，与一般的超声测距系统相比，除具备一般测距系统具有的功能外，该系统还具有低功耗、高精度、工作可靠、人机交互界面友好等优点。由于超声传播速度与环境温度相关而采用声速温度自动补偿技术，根据测量不同距离和不同的反射材料，回波信号强度从几毫伏到几百毫伏变动，因而采用两片AD603组成AGC自动增益控制电路与低噪放大器 NE5532 级联使用的方式组成超声检测信号放大电路，提高超声检测系统的检测范围和系统的适应性，使的系统获的较好的整机性能。由于超声波的传播距离与它的振幅成正比，为了使测距范围足够远，可对单片机输出方波信号进行功率放大后再加在超声波换能器上，因而先由三极管8050进行功率放大，再通过由六非门CD4049接成推挽方式的驱动电路将振荡信号的幅度放大一倍，再接到超声波换能器，从而增加了超声波的传播距离，扩大了测距范围。-err

12864液晶在出厂时其对比度已经调好，所以用户在使用的时候第三管脚可不用接任何东西，本实验板上为了兼容多家12864液晶所以加了液晶对比度调节电位器，若用户使用我们配套的12864液晶可不用管它，液晶的第三管脚悬空就可以。有些液晶功耗比较大，用户在使用的时候可将液晶的第19、20引脚的背光不接，这样字体会很清楚-12864 LCD contrast, when the factory has a good tune, so when users can not access the third pin anything, this experiment in order to compatible with more than 12,864 on-board LCD so the addition of LCD contrast adjustment potentiometer, if users supporting our 12864 can not regardless of LCD, LCD" s third pin can be left vacant. Some relatively large power consumption of LCD, users can be used when the first 19,20 LCD backlight will not receive the pin, so that fonts will be very clear
