看看nanosleep函数。

您可能需要重新编译内核以增加定时器中断频率，以便提高纳米睡眠功能的分辨率。

我不知道芯片上的时钟速度是多少，如果可以达到分辨率的话，你可能不得不将代码移到内核中。

Take a look at the nanosleep function.
You may need to recompile your kernel to increase the timer interrupt frequency in order to improve the resolution of the nanosleep function.
I do not know what the clock-speed on that chip is, you may have to move your code into the kernel, if that fine of a resolution is attainable.

谢谢...我现在使用18.432 MHZ时钟我需要通过软件产生100纳秒的延迟。我正在使用Kernal 2.4.19 ..请giude me ..

Thank ... I am using 18.432 MHZ Clock now i need to generate 100 nanosecond delay through software. i am using Kernal 2.4.19.. please giude me..

您是否看过nanosleep功能？

你呢有重建内核的经验吗？如果你这样做了，你知道如何将新内核放到你的设备上吗？

Did you take a look at the nanosleep function?
Do you have experience in rebuilding your kernel? If you did so, do you know how to get the new kernel onto your device?
