device data input (2) Mosi-master device data input, output from device data (3) sck-clock signal generated by the master device (4) CS-enable signals from the master device Among them, CS is to control whether the chip is selected, that is, only when the chip selection signal is a pre-defined enable signal (high potential or low potential), this chip operation is effective. This allows connecting multiple SPI devices on the same bus. I have introduced so much about the SPI bus theory.

In the previous article, we will focus on the differences between k9gag08u0d and k9gag08u0e. In addition to these differences, there is also a place to focus on. Next we will explain in detail. The first step for uboot to start from nandflash is to copy the first 8 K code of nandflash to the internal SRAM of, and then run the command, the 8 K code will copy the complete uboot code from nandflash to the off-board memory of the 6410

First, Introduction HyperTerminal is a universal serial interaction software with Windows operating system, which can be configured for router switches and so on. Use a modem, a 0-demodulation cable, or an Ethernet connection, and then call this program to connect to other computers, Telnet sites, bulletin board systems (BBS), online services, and hosts. We can use it to debug the circuit is feasible. Embe

input conversions, or 1 if an error occurs, otherwise 0 is returned;Iconv_close is to close the pipe (channel).If for a large number of encoding needs to be converted, the above function covert is not suitable for this way, one is the memory limit can not be called once, second, if multiple calls will frequently open a coded pipeline (channel), resulting in waste of resources, the best way is to take apart the function according to the situation use.Second, arm-linux transplant process1) http:/

There are four small LED lights on the tianembedded 2440 Development Board. The random band test software is developed using C ++. However, I prefer the C # language, so through the analysis of the BSP package of tq2440, the four small LED lights are controlled through gpio ports. Therefore, as long as the C # is used to control the gpio port, it can make the LED

At this time we can find the three connections shown in the Device Manager of the computer, and see here that our driver has been installed successfully. The next step is to develop.Step Two: Login to the system1. Find the latest version of Xshell software on the Internet and install it on the PC. After the installation is complete, open the

Transplantation of the yaffs2 File System Editor: The previous file systems are all friendly built-in file systems. The GUI is based on qtopia. This file system has powerful functions. Here we can port a root file system by ourselves, but this is only the most basic system, which helps to understand embedded development. The file system production process is similar, but the production tools used are different. The file system created here mainly refe

/usr/lib.In the practical application of embedded Linux systems, 1 and 2 are often used. Some relatively simple embedded systems use 4 or 5 paths to regulate dynamic libraries. 3. It is rarely used in embedded systems because many systems do not support lD. So. cache.The steps 4 and 5 are very simple. You only need to put the required libraries in/lib or/usr/lib to solve the problem that the library cannot be found. However, for larger systems, not easy to manage.According to the actual situatio

Arndale is a development board developed and developed by insignal. It uses Samsung's most advanced SoC Exynos5420 and carries 3 gb ram and 4g emmc (this is a bit pitfall ), AX88796 10/100 m nic (slightly pitfall), USB 3.0, etc. This time, Samsung did not know why it removed the SATA interface !! According to the official wiki, I want to download the Android source code. I found that it took a long time

Android system by default only the data directory is readable, and other directories are read-only, so do aSome software debugging, you need to transfer library files or binary files to these directories, below I will introduce how to modify the textFolder to avoid the need to recompile Android source code.1 Console modificationsFirst of all, we want to enter the highest access to Android, when the default is not the highest permissions, in the termin

This article focuses on how the Arduino Development Board works from a hardware perspective. Most of the articles are about Arduino software. However, an in-depth understanding of its hardware design can help you take a solid step in the Arduino journey. Mastering the electronic design of the Arduino hardware will help you learn how to embed Arduino into the des

compilation. If you forget to save it, it is equivalent that you have not modified it. Now let's program C code. In order to standardize the program, I need to make some adjustments to the program for further explanation. Create two folders named driver and main respectively. As shown in, Change hello_world.c to main. C and put it in the main folder. After modification, as shown in Next, let's modify main. in C, I will first introduce the purpose of this Code, which is to control th
