A 51 Development Board was developed recently, as shown in. This board is very simple,All I/O ports are extracted, and Peripherals can be expanded by themselves. P0 is used to pull up the resistance,11.0592 M crystal oscillator, reset key, DC power plug, DC power self-locking switch, microcontroller lock seat, expansion of three VCC And Gnd. Compared with the large development

This time we will introduce a classic problem in the counting combo: dimer lattice model. The question is: How many different dominoes are there for a 64-square chess board? Here, the covering refers to covering the entire board without repetition or omission. It is a possible method of overwriting (the picture is from Wikipedia ): The answer to this question is 12988816. A very large number is defini

I. Causes and principlesCause: In the past computer burning write bootloader to NAND is using JTAG and Jflash,jtag is connected with the port, the current computer is generally not the same mouth, now generally used cheaper to start the J-link, using USB, you can no longer use the previous Jflash burned write. It is therefore necessary to find a way to J-link write NAND. The following instructions j-link the principle of burning nand. With the realarm2410 Development

The 5th chapter: Build the test environment of s3c6410 Development BoardThis chapter mainly introduces the Android system installed on the OK6410 Development Board developed on the basis of Samsung's launch of the s3c6410 Development Board.Install serial debugging tool: Minicom1th Step: Detect whether the current system supports USB to serial port2nd Step: Install Minicom3rd Step: Configure Minicom4th Step: Test minicomThe method of erasing Nandflash

First, install the Serial debugging tool: MinicomThe Development Board has a serial port. Can be connected to the PC via serial cable. The Linux driver sends debug information to the PC via a serial cable while outputting debugging information, so the Linux driver can view debug information directly on the PC.Note: Since many new PCs and laptops do not have a serial port, it is recommended that readers buy root USB to serial cable (be sure to buy good

problem Description:Stm32 provides a number of IC entry-level development boards, the price is quite cheap. Stm32f0308-discovery is an entry-level Development Board for the CORTEX-M0 architecture. The following is a brief introduction to it.io Convenient:? As long as a USB cable is connected to the PC for development, theIO from the stm32f0308 IC is drawn from the Development Board to facilitate the use of

Note:ArticleContent Source: ComputerAlgorithmDesign and AnalysisDemoProgramIt is done by myself. Please advise me more! In a checkerboard composed of 2 ^ K * 2 ^ K squares, if there is a square different from other squares, it is called a special square and changed to a special checkerboard. Obviously, there are 4 ^ K positions in the special square on the board. Therefore, for any k> = 0, there are 4 ^ k different special chessboard. The special ch

File transmission through serial ports between the embedded Linux System and the host I think if I want to download something from my PC to the embedded Linux System of the Development Board, many people will first think of using network tools such as TFTP SFTP to download it from the network port. But if the network is not used, what should I do if I can only download it through the serial port? At this time, there are two tools that can help you:

First, the primerRecently again on the algorithm class, now want to feel a bit ashamed. I have studied for one semester during the university. To now but still feel just the teacher talked about the topic to understand, and did not learn some of the algorithm of some good analytical methods and ideas, encountered a new problem often feel very tricky, after a bitter lesson to think or good to learn again. To be able to understand the ideas and core of each algorithm, at the same time also exhorts
