1 static routes and default routes
Introduced:
When the router forwards the data, it needs to find the appropriate route in the routing table now, there are three ways
(1) Direct-connect Routing: Routers automatically add and own direct-attached routes
(2) Static routing: Routes added manually by an administrator
(3) D

This proves that the code is correct and is generally caused by not enabling rewrite.

The main function of real-time clock (RTC) is to keep the clock running when the system powers down, so as not to lose time information. The RTC module is integrated with the internal registers bcdsec, bcdmin, bcdhour, bcdday, bcddate, bcdmon, and

Lead: first, I will share my experience. to do one thing well, I have to spend some time, and then I will learn more, think more, practice more, communicate more, and summarize more to find my own problems, then we must overcome this problem. When the status is poor, we must adjust it in time. If you are a beginner, you must think
anti-ring: OSPF is a loop-free dynamic routing protocol. But only for internal and intra-OSPF areas. There is no good defense against the external routing loops introduced into OSPF, so when the OSPF External route is introduced, the routing is filtered to prevent the loops caused by manual configuration.
Prevent Database overloading: By limiting the number of external routes, filtering out useless routes
The real-time clock (RTC) unit can work with a backup battery when the system power is off. RTC can be operated by using STRB/LDRB ARMSends 8-bit binary Exchange Code (BCD) value data to the CPU. The data includes the time information of the year, month, day, week, hour, minute, and second.The RTC unit operates on an external 32.768kHz crystal oscillator and can
Last time I wrote b4a to access RTC remote services through XMLRPC, some netizens asked how to access the binary stream of RTC Web through b4a, such as how to download
The image on the server actually accesses the binary stream and the access string. The difference is that, because the HTTP protocol is used, the binary stream needs to be converted
Base64 encoding, and then convert base64 back to the binary
In Linux, the support for S3C2440 RTC is very complete. We only need to make simple modifications to use RTC.

A timer is often used in LINUX, but in LINUX, it is not as convenient as SETTIMER () in WINDOWS. There are three main methods: SLEEP/USLEEP + separate thread; SETITMER adds Signal Processing SIGALRM or RTC mechanism. Here I am talking about using the RTC mechanism to implement the Timer class. This method is the most advantageous. It is separated from the SLEEP and SIGALRM signals in the traditional sense,
Summarize:
The RTC function module is divided into two parts, one is the RTC_CR and other registers which deal with the APB1 bus interface, they are powered by the system, the other is the RTC core part, respectively has RTC_PRL,RTC_DIV,RTC_CNT,RTC_ALR, each is powered by the battery separately, But they all have RTC. 32.768k Clock Available

RTC (Real Time clock): Realtime clockBCD code: 4-bit 2 binary to represent the decimal form within 10.RTC Clock Source: LSE (32.768KHZ), HSE_RTC, LSI. After a precise calibration (RTC_CALR). The 7-bit prescaler is then divided (rtc_prer, default 127+1=128) to produce a ck_apre () clock. Again after a rough calibration (RTC_CALPR). Then go through Rtc_prer (a synchronous 15-bit Prescaler (default value =256)
