The default operating frequency of the S3C2440 CPU is 12 MHz or 16.9344 MHz. The maximum operating frequency is 12 Mb. The use of the PLL circuit can generate a higher clock speed for the CPU and peripheral devices. The S3C2440 has two PLL: mpll and upll, which are dedicated to upll and USB devices. Mpll is used for CPU and other peripheral devices. Mpll generates three clock frequencies: fclk, hclk, and Pl

Recently, the job is busy, it is inevitable to neglect his girlfriend. Then wrote a small program to remind her to sleep. I wrote the original function with bat, with the following code: @echo offTitle%date%%time:~,8%Mshta vbscript:msgbox ("Yang Huachu! It's bedtime! ", 36," said the Master, "(Window.close)Mshta vbscript:msgbox ("Yang Huachu! Take the pills! ", 36," said the Master, "(Window.close) Mshta code that is used to invoke other languages in the batch process. Here I use it to invoke th

Write Java applications. First, define a clock class--clock, which consists of three int typesMember variables represent hours, minutes, seconds, and a construction method for three member variables (hours, minutes, seconds)For initialization, there is also a member method show () to display the time of the clock object. Second, redefineA main class that creates

Tips for setting a multi-time clock in Win10 and win10 Tips for setting multiple time zone clock in Win10. This article will introduce how to set multiple time zone clocks and how to use the "alarm and clock" application to track more time zones, if you are interested, refer to the following tutorial. The Win10 system allows you to configure a maximum of three

As long as the digital signal processing circuit, there must be a clock signal. In the LCD panel, the pixel clock is a very important clock signal. The frequency of the pixel clock signal is related to the working mode of the LCD panel, the higher the resolution of the LCD panel, the higher the frequency of the pixel

C language time. h clock () function test program running time method, time. hclock The clock () function can be used to calculate the execution time of a program in C language. _ Cribd clock_t _ cdecl _ MINGW_NOTHROW clock (void); (it can be regarded as clock_t clock (void );) This function returns the number of CPU

By default, the operating frequency of the S3C2410 CPU is 12 MHz. The PLL circuit can generate a higher clock speed for the CPU and peripheral devices. The S3C2410 has two PLL: mpll and upll, which are dedicated to upll and USB devices. Mpll is used for CPU and other peripheral devices. Mpll generates three clock frequencies: fclk, hclk, and Plck. Fclk is used for CPU cores, hclk is used for AHB Bus devic

1 questions?? In the following test program, if the CLK_CKDIVR in the INIT_CLK () function is |= 0x08 and the '|' is removed, then the function implementation of TIM1 is the same as the preset (10ms interrupts once), However, the PWM frequency of the TIM2 is higher, and if added, the TIM2 function is the same as the preset (which produces 1Hz PWM), but the TIM1 cycle becomes longer;?? Tried a lot of tests, both are invalid (buy the development Board and another GS from the artboard test is also

This article summarizes and introduces the code for implementing analog clock using Python. There are three examples in total, and the last two are implemented based on QT. if you have any need, you can refer to the Python recommendation for implementing analog clock code. # coding=utf8import sys, pygame, math, randomfrom pygame.locals import *from datetime import datetime, date, time def print_text(font

shutdown Alarm clock refers to: mobile phone shutdown, as long as the phone and electricity as long as the alarm clock time will automatically start the alarm clock. 1. Enter the phone "application" management interface, click on the Desktop application icon open. 2. Then we go to the "clock" (the previous step

One: Preface The clock is the pulse of the whole operating system, which provides the basis for the process scheduling and timing events. In addition, many of the operations of user space depend on clocks, such as select.poll,make. Operating System Management time is divided into two types, one called the current time, That's the time we spend in our daily life. This time is generally stored in CMOS. The motherboard has a specific chip to provide tim

Development environment: Delphi 7Development name: Clock componentDevelopment note: The clock can switch pointer style and digital style, you can set the time, minutes, seconds and the value of the display color, can be opened and paused, you can set the display size. Recently in the study of Delphi, in different ways to embody the process of learning, just began to draw the

Jason's scribble OAL system clock 1. Relationship between system clock and Kernel Wince 5.0 uses the Real-Time Kernel of preemptible multitasking Based on Time slices, and each thread can set the size of the thread time slice as needed (refer to the cesetthreadquantum function). The default value is 100 ms, the default value dwdefathreadthreadquantum can also be set at oeminit. In the kernel source file, v

Clock cycle The clock cycle is also called the oscillation cycle, which is defined as the reciprocal of the clock pulse (it can be understood that the clock cycle is the reciprocal of the single-chip microcomputer external crystal oscillator, such as the 12 m crystal oscillator, its time cycle is 1/12Is the most basic
