delay time

IntroductionI believe that all the learning of JavaScript know that it is a single-threaded language, which means that JS can not be multithreaded programming, but JS has a ubiquitous asynchronous concept. In the early days, many people will

The three processes above are all delayed for the same time, let's modify them and try to delay them for different times.void TestA () {int i = 0;while (1) {disp_str ("A."); Milli_delay (300);}} void Testb () {int i = 0x1000;while (1) {disp_str ("B."

For some frequently triggered events such as scroll, resize, if the normal binding event handler function, it is possible to repeatedly trigger events in a very short period of time, greatly affecting performance. Therefore, for this type of event

Catalyst 4000 and Catalyst 5000 of the Catalyst Switch series (Catalyst 6000, running CatcOs) support some form of authentication, starting with code 2.2. Added the latest version. TACACS + (TCP port 49, not xtacacs udp port 49), remote access

The delay time set by the timer is not guaranteed. Because all JavaScript single-threaded asynchronous events (such as mouse click events and timers) executed in the browser are only executed when it is empty.SetTimeout will need at least a delay of

There are no empty statements in the standard C language. But in the MCU programming of C language, it is often necessary to use a few empty instructions to produce short delay effect. This is easy to achieve in assembly language, write a few nop on
