This article will build an engineering template based on the Nucleo Development Board and KEIL5.14, consisting of a few parts:1, the establishment of the project template2, the Stlink set and the Forever water lamp1, the establishment of the project template1) before building the project, first set up a folder to store the template files, we call it template。 Then set up 6 subfolders: Doc,libraries,listing,

Overall framework:First, the sending side1, the camera through the V4l2 interface to get YUV video format, can be played on the Win7 with Yuvplayer2, using the 4412 Hardware Encoding module MFC provides the interface for hardware coding, get. 264 file, can be played on the Win7 with VLC.3. Stream the. 264 file through the live555.Second, the receiving end1. Use the live555 to receive the. 264 file with the send-side connection.2, with 4412 Hardware Encoding module MFC provides the interface for

In the learning of embedded, in the use of Ubuntu to connect the development Board when the software setup problem is plagued by death, multi-find, is not the configuration after 2013, in this, chat with you about the setup of the Development Board, I new study, may write too shallow, readers do not spray.This article

　　Compile the official linux-2.6.30.4 kernel download to the TQ2440 Development Board the solution for the ongoing restart　　Check the log information for the Development Board to start printing, and the official startup log pair is not consistent with the discovery Cross compiler version.

Use HL340 (CH431) usb to connect to the 44B0 Development Board through minicom in LUbuntu13.10 and use lsmod | grepusbserial to view the usb to serial port device. Lsusb allows you to view information about HL340, such as iVender and iProduct. You can use the dmesg command to view the USB-to-serial access status, for example, the output is similar to ldquo; ch341arenowattachttyU Use HL340 (CH431) usb to co

The previous two articles respectively introduced the MINI2440 Development Board to run the bootloader and kernel, to here after the system is actually stuck in a "zombie" state---Unable to mount the root file system.Here's how to make a root filesystem and mount it to the kernel---that allows the kernel to access directories and files in the file system. From the user's point of view, the file system is no

s3c6410 is a low power, cost-effective RISC processor from Samsung, which is based on the ARM11 core and can be used in mobile phones and general processing applications. s3c6410 2.5g and 3g 2d acceleration, display processing and scaling, and also integrates a mfc mpeg4/h.263/h.264 codec and vci decode to provide real-time video conferencing and NRSC and pal format tv output. Linux installation configuration and test minicom steps:First step: Detect whether the current

8th: Make the Development Board sound: BuzzerOne, Linux-driven code reuseThere are many ways to reuse Linux-driven code. The standard C program can be used in the way. Put the code you want to reuse in a different file (declared in the header file). If you want to use certain features, include the appropriate header files (this is called static reuse). You can also use another way of dynamic reuse, where a

The buzzer is a hardware device on the s3c6410 Development Board. You can control the buzzer by writing a specific value to the register. This chapter implements a complete buzzer driver (which can be turned on and off) when the driver is implemented differently than the LED PWM drive will consist of multiple files. This is also the standard implementation of most inux drivers, which means that a complex dr

Through the study of this chapter I learned the following knowledge:First, the knowledge of buzzer: Buzzer is also known as PWM (pulse width modulation), the basic principle is to control the buzzer by pulse to open and close, the output pin of the timer and the transistor of the buzzer connected, this circuit transistor is PNP, when the pin is high, the transistor is in saturation, circuit conduction, Current flow through the buzzer, at this time the buzzer audible, conversely, when the pin is

The main example of this is the buzzer driver, the buzzer is the s3c6410 Development Board comes with a hardware device. The first section of Linux-driven code reuse, code reuse is divided into static reuse and dynamic reuse, the code to be reused is declared in the header file, this is static reuse, the Linux driver can use the resources in another Linux drive, which is dynamic reuse. One of the code share

The buzzer is a hardware device on the s3c6410 Development Board. You can control the buzzer by writing a specific value to the register. This chapter will introduce the implementation of the buzzer to the original plow and achieve a complete buzzer drive (can turn the buzzer on and off). PWM time-driven implementation is different from the LED driver, the PWM driver will be composed of several files. This

Environment: the ARM development board is ok6410, and the host is ubuntu10.04. 1. Preparation: Use the optical disc arm-linux-4.4.1.tar.gz tool to decompress the tool to the/usr/local/ARM directory (Add/usr/local/ARM/bin to the environment variable). Download The opencv2.2 source code; install cmake build-essential; install necessary libraries: libgtk2.0-dev libavcodec-dev libavformat-dev libswscale-dev lib

First, you must have a wireless NIC driver on the arm Development Board! The 2.6 kernel supports more than 10 wireless Nic chips. When buying NICs, the last chip is available in the Linux Kernel! It is troublesome to find a proper driver! Next we will run the command to connect to the AP. I used the Vista system to set up a simulated AP point mode to ad-hoc (this should all be simulated as point-to-point

The Linux Development Board requires several conditions to turn on the Telnet service:1. File system support TelnetBusyBox default is to put the Telnet and telnetd function into the, so this step is generally saved.2.
