Abstract: The Real-Time Multitasking system mechanism and performance are described comprehensively, and a method to realize this Real-Time Multitasking mechanism is proposed: the time slice rotation scheduling method. This scheduling algorithm is implemented in microcontroller and an example of its application in the train gate friction coefficient test system is provided.Keywords:Real-Time Multitasking; time slice; rotation scheduling;
ATMEL Corporation announced the launch of its AT91CAP7A-STK entry-level development kit, designed to evaluate its
ProcessorCustom cap
Microcontroller(MCU) series of entry-level tools. The custom MCU of cap7 allows designers to transfer from the "ARM7 and FPGA" design to a low one-time R D cost (NRE)
Single ChipSolution: the cost per device is reduced by about 30%, and the performance is improved by 8 times. The static power consumption and working po

When using mmc18 programming, you must add the connector script file (*. LKR) and header file (*. h) at the same time ). The connector script file mainly provides the storage space available for the connector and how to use the space, which
We learn MCS51 single-chip microcomputer and AVR MCU, or PIC microcontroller, or MSP430 MCU, whether it feels that he can become an engineer? I'm here to say what I think.We learn these single-chip computer, the first study of theoretical knowledge, this is generally the theoretical knowledge of books, such as the introduction of the development of single-chip microcomputer, the application of single-chip microcomputer, the principle of single-chip mi
Source: again out of a scheduler, small resources microcontroller is worth a useSelf-thought has the following characteristics:1) Super portability, CPU-independent, almost any CPU that supports C programming can be used! (This article only takes 51 single-chip microcomputer as an example, but can actually be transplanted arbitrarily)2) Small and small, the principle is very simple, a look will understand.3) province and province, can be said to the R
contrast, the MCS-51 microcontroller command system has a total of 111 commands. The introduction in this book is mainly aimed at the 8-Bit Microcontroller PIC16F877 of the mid-range Microchip Company, which has the on-chip (On-Chip) EEPROM data storage and flashProgramMemory, which can realize in-circuit debugging and In-circuit serial programming. With the help of the Economic online debugger (MPLAB-ICD)
In the learning of the microcontroller only really know what the C language is, it is to do ~ but the C language used to embed only its small part of the application, there are many places.We are not in the process of writing, many errors even if the compiler passed the results of our expectations, it is not difficult to find out where the wrong? I think that language can be called language, it is certainly a tool, a mutual communication between each
Parallax Scrolling is an emerging web page design technology. It enables multi-layer backgrounds to move at different speeds to form a three-dimensional motion Parallax effect, although purely visual, however, the visual experience formed during content scrolling is excellent! Today, I will share with you 35 pieces of web design that use the parallax scroll effec
This effect is achieved by following the chirs coyier's Parallax tutorial. After the chirs permits the use of the star background.
Running effect:Watch here: http://www.fofronline.com/experiments/parallax/#experimentThis effect can be properly previewed in Safari 4 beta and Google Chrome, so that JavaScript is not required.(However, it cannot be viewed in IE7 or earlier versions)
Implementation Method
Cocos2d-x has parallaxnode parallax node, the inspection as the name implies, is caused by different movement rate effect.I think we all played the legend of the turret, his background has a vision and a close-up point, and you swipe the screen when the vision and close-up at different rates of movement;Today we are here to achieve this effect.Key words: ScrollView, ParallaxnodeTo slide definitely need to scrollview, we generally use Cocostudio to bui
Parallax scrolling is one of the simplest solutions that website administrators can rely on. In particular, they need to directly affect the faster Website access speed and enjoy what they want. The webpage parallax plug-in can be used. Currently, many resources on the Internet provide parallax tutorials for interested website owners to learn, and more visitors a
Parallax scrolling is a unique form of webpage content. Its basic principle is to make multi-layer backgrounds move at different speeds to form a three-dimensional motion effect, delivers an excellent visual experience. As a hot trend in web design this year, more and more websites are applying this technology. Today's articleArticleI would like to share with you the exquisite cases of applications in the parallax

Reference article http://cn.cocos2d-x.org/tutorial/show?id=1322Parallaxnode is the meaning of the Parallax node, when we face a background screen, if the background can use this node when scrolling, its function is to let the child nodes have a different rate of movement, so that we can make some child nodes move slower, and some of the child nodes move faster. This creates the effect is the distant scenery movement fast, and near the scene movement f
principle of being a person, you will not be able to do anything smoothly. The same is true for game design. If the game's design intention or idea is modified halfway through game development, it will be expensive. Sun Tzu said: "If you do not fight, the temple will count as the winner. If you do not fight, the temple will count as the winner. If you do not fight, the temple will count as few as the winner. If you calculate more than one, you can calculate less than one!
