delay function

I have done the system, separate stand-alone system (2005), CS System (2010), Real-time system (2015), each system has a "delay" function: scheduled scheduling; This blog is about the delay function in real-time systems (based on the Unity3d game

The first class of delay function prototypes are: (Busy, etc.)void Ndelay (unsigned long nsecs);void Udelay (unsigned long usecs);void Mdelay (unsigned long msecs);Description: Kernel functions ndelay, Udelay, and mdelay are useful for short delays,

The second way to address the CPU usage of the delay function in the previous section (up to 50%) is to use the message mechanism to wait for messages or timeouts through API functions MsgWaitForMultipleObjects, thus avoiding the use of cyclic

In many cases, our program, before performing the next step, will need to wait for the execution of the previous one, which is most evident in the asynchronous operation, or in the program that uses the message loop mechanism to communicate. An

The C language code below uses a function that generates random numbers, and a delay function. Please carefully observe its display effect. From the following code, we can draw an important conclusion: when the above two kinds of functions are put
