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

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

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)

After experiment: Except for 2 signals that cannot be capturedAs long as the parent process does not define the signal, when the signal is captured, the parent is processed by defaultThe parent process is defined, the child process is undefined, and the parent process is handled as defined, and the child process is handled by default;Both parent and child processes are defined and captured to be handled in their own way.Characteristics of the parent-child process
After the user presses the Start button to start the Capture function, the list box automatically displays the eligible packets with simple parsing. Right click on the content, pop-up the following picture of the menu:
Select "Analyze" to show the following screen:
In the illustration above, the left and the lower-right sections are the results of the analysis, and the upper right is the original binary, and when you select an item on
When we need to collect a Web page content on the Web, if the image on the target site to do the anti-theft chain, we directly collected pictures on their own site is not available. Then we use the program to download the image on the target website to our website server, then we can call the picture. nbsp; This article will use PHP to achieve remote image capture function. Basic flow: nbsp; 1, get the target site image address. nbsp; 2, read the pic
We are often confronted with the problem of running apps on the iphone or on the ipad tablet, sometimes opening an app and then "flashing back". For developers, this is definitely a headache. So how do I get to the iOS device crash log? This provides some simple ways for developers to communicate with users.
It is normal to encounter a program crash in iOS development, how to catch exception information when a program crashes and notify the developer?
Here's how to implement this in iOS:
1. A
Whether in the computer or mobile phone, screenshots we often use, then how the notebook screenshot ah? Want to write a notebook computer tutorial, but do not know how the notebook screenshot. For the computer master, notebook screenshot is a piece of cake, but little white friends, it is inevitable not understand. The following Pepsi net Small series for you to introduce 3 kinds of notebook screenshots, small white friends to watch Oh.

A man on the Internet uses this method:
ReadOnly: The text box is not input.
[Ctrl + A All SELECT Note: If the need to introduce external JS need to refresh to perform]
Onpropertychange can be used to capture text change events, the test success!
Extras! WORD2013 also has screenshot function! No QQ, no keyboard screenshots, we can also easily handle screenshots. What, you don't know what to do? It doesn't matter, just look down and see!
To get a screenshot of the procedure in Word2013:
1, open the window we need screenshots.
2. Open a document with Word2013, position the cursor where we need to insert the screenshot, switch to the Insert tab, click Screenshot under the Illustrations option group, and then select the Screen Clip
First, we open office into the "Insert" menu under the "screenshot" as shown below
Second, click on "Screen Capture" will appear after you have hit the program of the page of the shortcut screenshot options, here I first selected a Web page to do the test, the following figure
Click here to instantly show the perfect screenshot below
Third, another screenshot of the way "screen clipping" Select this option we can
