On software, we take full advantage of the low power modes of the MCU to finish the task in ISR (interrupt service routine), so, the power of system rest with the ISR executive time.

在软件设计上，充分利用所选单片机的低功耗模式，让检测任务在中断服务程序中完成，使系统的功耗主要取决于中断服务程序执行的时间。

At last, in the section of software design, startup code programming, operating system choosing and transplanting, task design, drivers design and interrupt service routine design had been discussed.

最后，在软件设计部分探讨了启动代码编写、操作系统的选择和移植、任务规划和设计、驱动程序设计以及中断服务程序设计。
