The appearance of "one machine" brings the efficient and quick office way for the enterprise. In today's network era, the new form of "network integration machine" will bring us what kind of new office form? Cisco ISR 881 is a multi-service router (Cisco 881) can be called a "network integration machine", he integrated the router, firewall, IPS, IPSec VPN, VoIP a
Interrupts are an important part of embedded systems, which leads to a lot of compiler developers providing an extension-letting standard C support break. The representative fact is that a new keyword __interrupt has been produced. The following code uses the __interrupt keyword to define an interrupt service subroutine (ISR), please comment on this code.
__interrupt Double Compute_area (double radius){
Double area = PI * radius * RADIUS;printf ("ar
ISFP is a command package for service interruption. There are three scenarios for creating ISR:1. Eight commands in An ISFP package can satisfy ISR requirements.2. ISR can occupy multiple consecutive ISFP (provided that the following interruptions are not used)3. ISR is located outside of istIn the preceding figure, B
1. System interruption and clock cycle
1.1 system interruption
Interrupt is a hardware mechanism that notifies the cpu Of an asynchronous event. Once the interrupt is identified by the system, the CPU stores partial (or all) context values, that is, the values of some (or all) registers, and jumps to a special subroutine, it is called the interrupt service subroutine (ISR ). Interrupt Service subprograms are used to process events. After processing is
Interrupt service routines (ISR)
ISR: interrupt service routine)
The so-called interruption refers to an external event (such as a level change, the occurrence of a pulse edge, or the overflow of the timer count) when the CPU is processing something) the request is processed by the CPU quickly, so the CPU temporarily suspends the current job and forwards it to the processing of the event. After the inci
In this tutorial we is going to learn what to navigate programmatically (or imperatively) by using the Router API. We is going to learn how to use the function Navigatebyurl to navigate using a manually constructed string, but we are AL So-going to learn-trigger route navigation by using the Navigate API method, which takes an array or arguments and A Parameters object.We is going to learn how to do both absolute and relative route navigation using th
How do I set up a wireless router? WAN port and LAN port are the key
Most users who have been familiar with broadband routers know that the ports on the broadband routers are divided into WAN ports and LAN ports. A Broadband Router has the following features during work: data streams from the LAN to the WAN are not restricted by default through the router, and da

Change the WAN port address, LAN port address, and DHCP address range.
Key points:The WAN port set by the router is a dynamic IP AddressVroObtain the IP address, change its own IP address and DHCP to another CIDR block so that it is not in the same CIDR block as the first vro.

3G network card is widely used, but mobile phones, laptops and other terminals need to share the network, use TL-MR11U to convert 3G signal to Wi-Fi signal, to achieve Internet sharing. Insert your 3G Modem (3G Modem) and set the wireless network to meet your needs. As shown in the following figure:3G application topologySelect the setting method you need to refer:At home, you use the broadband account and password. In the company, you use static IP addresses (bound to MAC addresses) and dynamic

I was asked about the dynamic route of vue during the interview today. I didn't answer the question, and I felt that it was not a rare question. I haven't read the vue-router document for a long time. Many of the things and concepts I use are not correct. When I come back, I am d
With the rapid development of wireless network, wireless router is an indispensable part of our life. Many friends have a cable router at home, want to connect to a wireless router, so as to achieve WiFi access, it's convenient, fast, well received by friends like. I am using the jhr-n835r wireless router, then the fol

Router mode, the router is equivalent to a wireless router, wired port as a WAN port, wireless LAN, all wireless clients can share a broadband line online. Its typical network application structure is shown in the following illustration.
Life is endless, tossing. Today, let's talk about the factors that affect our Wi-Fi signal.
A crowded channel.
If you have ever entered the "192.168.1.1" or "192.168.0.1" URL to set up your own router, you may find similar options.
