密码锁:根据设定好的密码，采用二个按键实现密码的输入功能，当密码输入正确之后，锁就打开，如果输入的三次的密码不正确，就锁定按键3秒钟，同时发现报警声，直到没有按键按下3种后，才打开按键锁定功能；否则在3秒钟内仍有按键按下，就重新锁定按键3秒时间并报警-Password Lock: According to set a good password, the password used to achieve two key input function, when to enter the correct password, the lock will open, if entered incorrect password three times, on the lock button 3 seconds, also found that alarm sound, do not press the button until the three kinds of after the Open button lock function otherwise, there is still a matter of seconds in the 3 button press, on the re-lock button 3 seconds time and alarm

LTC1446是一种采用12位逐次逼近式工作的A/D转换器。内部包含系统时钟、采样和保持、12位A/D转换器、数据寄存器以及控制逻辑电路。LTC1446每25uS重复一次“输入――转换――输出”。器件有两个控制输入：DIN CLK和片选（CS）。 内部系统时钟和DIN CLK可独立使用。应用电路的设计只需利用时钟启动转换或读出转换结果。当CS为高电平时， Dout处于高阻态且DIN时钟被禁止。

freescale MCF5485EVB开发板上中断操作示例，利用一个timer产生中断，另外3个timer作为GPIO，使3g个LED每隔1秒钟轮换亮一次。-freescale MCF5485EVB interrupt the operational example of the development board, using a timer generate an interrupt, another three timer as a GPIO, so 3g a LED light at one-second rotation time.
