In detail,
On each STM32 chip has two pins BOOT0 and BOOT1, these two pins in the chip reset the level state determines the chip after the reset from which area starts to holdLine procedure, see the following table:
Boot1=x boot0=0 boot from the user flash, which is the normal mode of operation.
Boot1=0 boot0=1 boot from the system store, this mode starts the program features set by the manufacturer.The Boot1=1 Boot0=1 is started from the built-in SRAM, which can be used for debugging.

To learn more about router Internet access configuration, it is very important for ordinary home users and to ensure our network security. The first thing to confirm is what your "Broadband Access Method" is like? Of course, the simplest way is to call your ISP (Internet Service Provider) for consultation. You can also make a quick judgment by using the network connection method you used to buy a router. Common Hardware connection methods include the

Ftp commands are one of the most frequently used commands by Internet users. A large number of internal FTP commands are used in both DOS and UNIX operating systems, familiar with and flexible use of FTP Internal commands can greatly facilitate users. For users who are currently on dial-up, if the ISP provides shell, nohup can be used, ftp will be the most cost-effective method for downloading. The ftp command line format is: ftp-v-d-I-n-g [host name]
A Siebel client Configuration tool has been released since the last time. Some friends have responded that they have administrator permissions, and it is a bit difficult to manually modify the configuration file to modify the trusted site, so I have made some improvements, this is a small one.ProgramIt is small but powerful. Because of the project environment, it also provides dynamic identification of the local network ISP to automatically write the

Recently, many people are still asking how to connect to a home network or a small network. What are the methods. Here I will provide you with various solutions based on my own understanding to see which one can be used. It indicates limited capabilities. I do not know if you can understand it.
1. access the Internet from one machine (direct connection)
2. connect multiple machines to the Internet and use a Broadband Router (express Connect)
3. access the Internet from multiple machines using v

The following is a function written by the author to write values to a specific address:
Void writetoflash (uint32_t offset, uint32_t date){/* Erase before writing */Int I;
Un_lock_reg (); // when writing data to flash, it is written through the system isp. Therefore, you need to write three values first. Friends who have routines can understand this.Ispcon | = ispen; // enable the ISP Function

When using a DSL connection, if you are using a DSL connection that has a fixed or static IP address, the configuration step is the same as described in the previous network configuration. You connect the Ethernet interface to the DSL modem and configure the IP address, subnet mask, broadcast address, and gateway information provided by the ISP. You should be connected to the Internet after you restart the network device. Remember, you may also need t
are RIP, OSPF, and BGP. RIP, OSPF is an internal gateway protocol that applies to the operation of a single ISP's unified router protocol, and a network operated by an ISP is called an autonomous system (AS). BGP is a router protocol between autonomous systems and an external gateway protocol. Rip is the longest-growing router protocol and the simplest router protocol. It is the acronym for routing Information Protocol, which mainly transmits routi

In the process of using the Active Accessibility SDK, I get the IHTMLDocument2 pointer from a handle to a window. Is there any way to get the IWebBrowser2 pointer from the IHTMLDocument2 pointer? I tried it on two interfaces (IHTMLDocument2 and IWebBrowser2) with QueryInterface, but it didn't work. I also tried to get IOmNavigator * from Get_navigator using Netscape's HTMLWindow2 pointers. Also ended in failure. Please advise the master.

① Export Speed
The so-called export speed, refers to the ADSL is also ISP service providers, such as telecommunications, Unicom, railcom and other specialized network services provider, to provide you with the speed of the network. If you want to surf the Internet, you have to go through the telecom Unicom and so on, so the first level of Internet speed is how much bandwidth

that computers within the network with the same IP address to access the Internet,
While saving the IP Address resource, it can effectively protect the computer inside the network.
The network environment is:
LAN uses 10MB/S fiber to connect to the Internet as a metropolitan area network, as shown in the figure.
The router chooses a Cisco 2611 with 2 10/100 MB/s adaptive ports. The IP address used by the internal network is 192.168.100.1~192.168.100.254, the IP address for LAN port fastetherne
It is very useful to know some methods for setting a Broadband Router. Here we mainly analyze the comprehensive description of the method for setting a Broadband Router. ADSL/VDSL PPPoE: A computer runs a third-party dialing software such as Enternet300 or a dialing program provided by WinXP. Fill in the account and password provided by the ISP, and dial the number before accessing the Internet each time; alternatively, your adsl modem has enabled the
access to online banking, online games, and other applications may occur.
C. The ISP address exactly matches the destination address accessed by the user with the ISP address pool, so that the traffic accessing the telecom address goes through the telecom link, and the traffic accessing the UNICOM address goes through the UNICOM link. This can increase the access speed of users. However, links are often un
login. Time Zone: select the corresponding time zone and click "Next" to go to the Internet access mode selection page. This Alpha router supports three common Internet access methods. You can select and set the required parameters based on your needs.
1) Dynamic IP Address: the IP address is automatically obtained from the ISP. Users accessing the Internet in this way do not need any additional settings. However, some ISPs may require MAC Address bi
access. The best example here is the 128 k isdn, which uses two 56 K channels at the same time to achieve a speed of K. When the ISP provides such a service, two independent lines are configured to connect to the same IP address.
You can see that, although there are EQL modules in Linux that allow you to use two data cards on the computer at the same time, unless the ISP provides the same IP address for
