Timers TIM1 and TIM8 use 16-bit counters and are the most complex timers of all timers included in the microcontroller. Timers TIM2 and TIM5 are 32-bit versions of TIM1/TIM8, but have less hardware included and therefore less options. Timers TIM3 and
The Timers can be cascaded to make more complex timing relationships, or longer periods. Internally only some timers can trigger others. This is a Master/Slave relationship and is handled by the SMS register. For example, you can see below that TIM8

Linux内部的时钟处理机制全面剖析 在 Linux 操作系统中,很多活动都和时间有关,例如:进程调度和网络处理等等.所以说,了解 Linux 操作系统中的时钟处理机制有助于更好地了解 Linux 操作系统的运作方式.本文分析了 Linux 2.6.25 内核的时钟处理机制,首先介绍了在计算机系统中的一些硬件计时器,然后重点介绍了 Linux 操作系统中的硬件时钟和软件时钟的处理过程以及软件时钟的应用.最后对全文进行了总结. ◆1.计算机系统中的计时器 在计算机系统中存在着许多硬件计时器,例如
上节已经详细说了下注入过程,最后寄生进程在宿主进程中下了个蛋,这下完的蛋有什么作用呢?接下来再具体分析一下. lib0的感染过程分析 对于本例注入的so动态库,首先看一下so的符号: $ readelf -s ./lib0.so Symbol table '.dynsym' contains 136 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000
1,运动原理 Js运动,本质来说,就是让 web 上 DOM 元素动起来.而想要 DOM 动起来,改变其自身的位置属性,比如高宽,左边距,上边距,透明度等.动画的原理就是把不同状态的物体,串成连续的样子,就像一本书,画了几个小人,然后一翻书,就看见小人在动.js动画也一样.不同状态的DOM,用定时器控制,就能得到动画效果. window.onload = function(){ var oBtn = document.getElementById('btn'); oBtn.onclick = f
