RTC Configuration1. For the second interrupt configuration, RTC is just a timer. It's no big deal!1. nvic_prioritygroupconfig (nvic_prioritygroup_1 );Nvic_prioritygroup,: Specifies the priority grouping bits length.This parameter can be one of the following values:Nvic_prioritygroup_0: 0 bits for pre-emption Priority 4 bits for subpriorityNvic_prioritygroup_1: 1 bits for pre-emption Priority 3 bits for subp

It's almost the spring festival. It's a little easier. I have just developed the RTC driver in wince6.0. Here I will introduce it. RTC is a real-time clock ). Currently, most 32-bit processors have their own RTC modules and external RTC modules. Generally, the external RTC i

This article was reproduced from: http://blog.csdn.net/little_walt/article/details/52880840The Linux system consists of two times: System time and RTC time.System time: Is the timer of the main chip to maintain the time, under normal circumstances will choose the highest precision on the chip timer as the timing of the system time benchmark, in order to avoid a long time after the system run a large time offset. Features are not saved after power-down

STM32 's real-time clock is a standalone timer Typically, a coin cell is added to the supply side of the backup area, and the RTC does not stop working when the mains power is not powered RTC can trigger a second interrupt, overflow interrupt, and alarm interrupt if the VDD power supply is active Backup Register BKPThe backup registers are 42 16-bit registers, they are in the backup domain, and when the VDD

RTC-driven framework in C/SRC/LIB/LIBBSP/SHARED/TOD.C, most of the functionality has been implemented, the entry function is Rtc_initialize (), BSP to achieve very few things.Beagle implementation in C/SRC/LIB/LIBBSP/ARM/BEAGLE/RTC.C, provides a rtc_tbl rtc_table[] array, the size of the array is stored in the Rtc_count global variable, each RTC_ The table element is a possible RTC chip, and Rtc_initialize

First, the contents of the experiment:The RTC0 of the configuration NRF51822 has a tick frequency of 8hz,compare0 matching event triggering period of 3 seconds and enables the tick and COMPARE0 interrupts. TICK interrupt in the drive indicator D1 rollover State, that is, the LED D1 at a rate of 8Hz rollover state COMPARE0 Interrupt Highlight Indicator D2 Second, the internal RTC structure of nRF51822:The NRF51822 has two

In an embedded system, real-time clock units can provide reliable clocks, including hour, minute, second, and year, month, and day. Even if the system is shut down, it can work normally (usually powered by a backup battery), and its peripheral does not require too many auxiliary circuits, typically, you only need a high-precision crystal oscillator. S3C2410 rtcFeatures: 1. Clock data adopts BCD Encoding 2. Automatic Processing of the year, month, and day of a leap year 3. An alarm is tri

Experimental content: Configuration of static routes and default routes Experimental environment: Cisco Packet Tracer simulator Experimental principle: Routing protocol is an important part of router software. Routers to choose the best communication route between interconnected networks are accomplished through these routing protocols. The role of routing protocols is also to establish and maintain routing

Configure routes and distribute routes by default in the network.The automatic summary function for configuring the summary routing (VPC) is disabled by default in some later versions of IOS. In some earlier versions of ios, the automatic summary function is enabled by default, you can use show running-config | inc rotue to check whether it is enabled. Automatically summarize the

the STM32 real-time Clock (RTC) is a stand-alone timer. The RTC module of the STM32 has a set of continuously counted counters, which, under the corresponding software configuration, provides the function of the clock calendar. Modifying the value of a counter can reset the time and date before the system. Since the clock only needs to be configured once, the next time the power-on does not need to be recon

A static route can be understood as a route to a specific destination, with a specific destination network addressIf a specific destination address is not specified, the default route is gone.The default route, also known as the default route , is a special static route with the destination address and mask configured as full 0 (0.0.0.0 0.0.0.0). When all routes in the routing table fail, the default route is used in order for the message to have a fi

Summary The real-Time communications (RTC) client of Microsoft Windows is comprised of a series of core components that provide rich communication characteristics. These features are presented to users through Windows Messager and other applications that use this application programming interface (APIS). This article outlines media-related features and the enhancements that these components provide. Application developers may want to integrate the

This sectionto is about the use of the RTC class, please download the ClassA20 Class library in https://github.com/tjCFeng/ClassA20 first.RTC, real-time clock control, if there is a backup battery exists, then the system shutdown after the power outage time is not lost, and still walking. After power-on can read the current value directly, and set to the system time, which is often used in embedded development of things. However, due to the involvemen

In Linux systems, the time periods can be hard time periods and system time periods. During hardware, the auxiliary power source (the power pool) can maintain a certain amount of time, while during system time, the system will reset each time it is re-activated, therefore, Linux usually performs hwclock-s synchronization when it is turned on, but in Embedded Linux, manual operations are required. First, you must initialize the RTC (Real-time clock)
