TIM1 16-bit advanced control timer
The advanced control timers have different uses:
1, the basic timing.
2. Measure the pulse width of the input signal (input capture)
3. Produce output waveform (output comparison, PWM and single pulse mode)
4, corresponding to different events (capture, comparison, overflow, braking, triggering) of the interruption.
The clock source of the advanced control timer
Here's how: To capture the entire desktop, press command-shift-3. The screen shot is automatically saved as a PNG file on your desktop.To copy the entire desktop, press command-control-shift-3. The screen shot'll be placed on your clipboard for your paste into another program. To capture a portion of the desktop, press command-shift-4. A cross-hair cursor would appear and you can click and drag to select t
Shell scripting is an essential skill for Linux OPS engineers and a very important skill, so it's only good to learn shell programming well. Basic grammar I will not speak, learn the C language of these languages, a little bit to understand the basis of shell programming, so we directly cut to the point.The 20th day of the classes:Today's Course Outline:
Functions in Shell programming
Write a script that automatically mounts
How to implement automatic mount with AutoFS

,www,inw and so on, as long as it is composed of these 3 characters, multiple characters are matched successfully.
How does the above match to, each one has 2 results? This is the child pattern (a child match), by default, in addition to combining multiple characters into a whole, and storing the parentheses, the part of the expression enclosed in a temporary buffer for subsequent regular expression calls. In this example above, we do not need to call later. So how do you block out this subexpr
Talk about JavaScript events, event bubbling, event capture, and blocking default events These three topics, whether in the interview or in peacetime work, are difficult to avoid.
Event Capture Phase: an event is searched down from the top level of the tag until the event target (target) is captured.
Event bubbling phase: The event starts at the event target and bubbles up until the top level of the page ta
For video capture in windows, Microsoft provides two SDK libraries: avicap and DirectShow. 1. Introduction to video for Windows
VFW is a software package for Digital Videos released by Microsoft in 1992. It allows applications to digitize and play video clips from traditional analog video sources. A key idea of VFW is that dedicated hardware is not required during playback. To solve the problem of large data volumes in digital videos, data must be co
The build of video capture graph a graph graph that captures audio or video is called a capture graph. Capturing graphs is much more complex than normal file playback graphs, DShow provides a capture graph Builder COM component that makes capturing graph generation simpler. The Capture Graph Builder provides a ICAPTU

Apply layer network packet capture using Hook Technology
Class: Class 2 of Visual ProgrammingINSTRUCTOR: Li DanStudent ID: 04311110210
Name: Liu Haiping
Abstract
Packet capture (interception) technology is mainly used in information security-related fields, especially firewall technology. With the development of the online game industry, m
PWM input capture mode
1. Concepts
Special case of input Capture Mode in PWM input Capture Mode
1. Each timer has four input channels IC1, ic2, IC3, ic4, and IC1 ic2, IC3 ic4, and set the ing between pins and registers.
2. Two Ti outputs Map two icx Signals
3. The two icx signals are valid at the opposite polar edge.
4. One of the two edge signals is selected as
Smarty built-in function capture usage analysis, smartycapture
This example describes the Smarty built-in function capture usage. Share to everyone for your reference. The specific analysis is as follows:
{Capture} can capture the output within the tag range and coexist in the variable without displaying it. There are
For the TIM5 interrupt handler, make the following explanation. (TIM5 interrupts include both timer update interrupts (timer count overflow), and capture interrupts)
U8 Tim5ch1_capture_sta = 0; TIM5 input capture state U16 Tim5ch1_capture_val; TIM5 input Capture value//TIM5 input capture interrupt function void Tim5
Wireshark and TcpDump packet capture analysis and comparison, wiresharktcpdump
Common packet capture analysis tools include Microsoft's Network Monitor and Message Analyzer, Sniff, WSExplorer, SpyNet, iptools, WinNetCap, WinSock Expert, Wireshark, and linux tcpdump.
Today, we conducted an experimental test to compare and analyze two of them. Other users can use Baidu Google to test yiha ^_^.

Some of the most recent difficulties in learning JavaScript, such as bubbling and capturing, have been mentioned many times, but I don't know where to apply it. Found some good Article FAQ, here to share with you.
Event bubbling and event capture were presented by Microsoft and Netscape, both of which were designed to address the issue of the event flow (sequence of events) in the page.

YY Live Assistant Desktop capture function only in the live broadcast we can operate, we only need to refer to the following methods to operate, the details are as follows
YY Live Assistant Desktop capture using method
1, we click on "Desktop Capture" in the interface, click to start Live, the effect is as follows
2, then we click "Desktop
In the measurement process, the high waveform capture rate is very important for the oscilloscope.Improves the ability of the oscilloscope to capture random events and low probability events.
Before describing the waveform capture rate, you must first understand the concept of dead time.
What isDead Zone Time? That is, the sum of the next collection and data
Let's start by opening the Chat window this screen:
Then click on the Screen Capture button under the Mvbox Video window to set it to the selected state (highlighted state) to turn on the Mvbox screen capture feature. Clicking the button again and setting it to unchecked will stop the screen capture.

Wireshark packet capture analysis-network protocol
Wireshark is currently the most popular packet capture tool. It can run in windows, Linux, and Mac OS X operating systems, and provides a friendly graphical interface. Wireshark also provides a powerful data packet capture function. It can capture the network data pack
For those who study websites or related programmers, HTTP packet capture tools are often used to track webpages. However, mainstream packet capture software such as httpwatch and httpanalyzerstdv are charged, and the cracked version is often unstable. In fact, many browsers now have built-in free packet capture tools. Today we will introduce several small series
PHP gets the output intercepted by $ Smarty. capture. name. To get the output after $ smarty-display and assign it to the php variable as a string, there are two methods: 1. ob_startob_start (); $ smarty-display (StockNewsgetLeft. tpl); $ stringob_get_cont you want to get the output after $ smarty-> display and assign it to the php variable as a string. There are two methods:
1. ob_start
Ob_start ();
$ Smarty-> display ("StockNews/getLeft. tpl ");

The effect of this experiment is: press and hold the button, then release, the serial port will print and hold the time.Capture principle. The counter has a capture function. There is no time to capture the timer can also be at work. Set to the rising edge of the capture, when there is a rising edge, will trigger an interrupt to enter the interrupt function.Clear
