These three classes are in the system. Text. regularexpressions namespace. They maintain an inheritance relationship with each other, such:
We start from the outside to the inside (I think it is better to understand). First, the match class indicates a final match. A regular expression does not necessarily have only one match. This can be done through match. nextmatch to try the following match. All groups in the regular expression can be obtained through the groups attribute of match. The Grou

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

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

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.

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
