一个手机副屏的时钟程序，基于OSE操作系统，可以看到实现的完整代码，但没有环境是不能编译运行。-a phone screen clock procedures, based on the OSE operating system, we can see the realization of a complete code, but no compiler environment is not running.

生成2KHz和8KHz的混合信号，使该信号通过上述滤波器，观察滤波前后的波形变化和频谱分布情况。-2KHz and 8KHz generation mixed-signal, so that the signal through the above-mentioned filter, filter before and after observation of the waveform and spectrum distribution of the changes.

基于 CPU 的精确计时器，时钟频率越高，计时越准 -on CPU precision timer, clock frequency, the higher the more time-

解决internet中声音传输的问题，我可是费了好大的劲才弄到的！-internet address voice transmission problems, but I charge a lot of the true succeeded!
