of received binary sequences (including the Information Code and CRC Code) by the polynomial. If the remainder is 0, no error occurs during transmission. Otherwise, the transmission is incorrect, I will not describe its principles here. When the CRC code is calculated using software, the receiver can calculate the CRC code for the received information code, and compare the result with whether the received CRC code is the same.In frame verification sequence of HDLc, crc16 is a CCITT-16 used in t

From the NAND bad command entry in uboot, we can see how uboot breaks down blocks separately.
It verifies the colomn address 4096 of last page in the block in the datasheet of NAND Flash below.
The specific process is as follows:
Device 0 bad blocks:[Do_nand]: Off = 00000000.[Nand_block_isbad]: 1 00000000[Nand_block_isb

included in the length field. The length of the frame header is 18B, including the destination address field of 6B, source address field of 6B, type field of 2B, and frame verification field of 4b, the forward code and the pre-frame delimiters are not included in the frame header length. Therefore, the minimum length of an ehternet frame is 64b (46b + 18B) and the maximum length is 1518b (1500b + 18B ). One purpose of setting the minimum frame length is to enable each receiving node to have eno
the image must be divided into the number of digits of the color, because since the image is stored in the form of "pixels", it is necessary to record the color value of the first "pixel, in this way, you can see the stored image when you open the image.
Record the binary digits occupied by the color value of each pixel, that is, the number of digits of the BMP image. There are different methods for recording the color value, such as using the RGB value, that is, recording the red) mix the colo

Let's take 1 + x2 as an example. As we have already said before, X indicates the weight, and X indicates the weight. Here is a weight with a mass of 2.1What does it mean? 1 indicates that the weight of 2 is 0.
1 + x2 indicates two conditions: 1 indicates that the weight with th
Samsung has also invested a lot of energy in the storage of NAND Flash. It has deep development for pure NAND Flash, onenand (NAND Flash module with controller), and NAND drivers. The NAND mentioned later will be based on Samsung products, including drivers.
The naming rules for Samsung pure NAND Flash (that is, the NAND flash storage chip without other modules) are as follows:

I believe many of my friends know that the win7 system already has self-built systems.The wifi hotspot function is implemented through several commands. Although it is simple, many people think this is very troublesome. After each restart, they must repeat the above steps to enable this Wi-Fi access point, for the convenience of everyone, at the end of the article, we will provide you with a batch processing to implement the several commands.

However, "#" cannot bond any character at will. It must be a valid C language identifier. In a single macro definition, the "#" or "#" preprocessing operator can appear at most once. If the calculation order related to the "#" or "#" prepr
simple way of saying that A is a digital variable, meaning that it can or has been linked to a number, and B is called a character (string) variable, meaning that it can or has been linked to a string.
Simple manipulation of strings
For numbers, there are some simple operations, such as arithmetic, which, if 3+5, is calculated as 8. So what can you do with strings? Try it:
>>> "py" + "thon" ' Python '

NAND read and write operations using 512 wordssection of the block, which is somewhat like a hard drive to manage such operations, it is natural that NAND-based storage can replace hard disks or other block devices. NAND Flash data is stored in the memory cell as a bit,In general, only one bit can be stored in a cell. These cells are bitline in 8 or 16 units, forming the so-called byte (x8)/word (x16), which is the bit width of the NAND device. Thes

In C #, decimal and hexadecimal conversion is very simple. The method is as follows:
Convert decimal to hexadecimal:
1 int a = 100;2 String strA = a.ToString("x8");
Convert hexadecimal to decimal:
1 int b= Int32.Parse("266", System.Globalization.NumberStyles.HexNumber);
