Development Board: tx2440 Development Environment: ubuntu12.04 In Linux, use Vim to compile program code (startup code, main program, and makefile), and perform cross-compilation in Linux to generate binary arm executable files, the shared directory of VMware is transmitted to the Window environment, and is directly run in arm norflash with jflash. Goals: 1) li

I have been buying a Development Board for three months and can finally make some small things. But I forgot later, so I decided to start taking notes. I hope to communicate with csdn My Development Board runs the kernel of linux2.6.24, qtopia for GUI, so QT for development

Tutorial: Compile u-boot1.1.4 and above to start the development board based on S3C2410 -- Linux general technology-Linux programming and kernel information, the following is the details to read. Someone has tried to compile U-BOOT 1.1.4 or above to start the S3C2410/SMDK2410 compatible development board? I recently tr

Download the dnw in the window to the board. Restart the board, set the

Recently debugged the serial port above the bottom of the s5pv210 you made. Because writing a program is cumbersome to test a serial port. So, a direct transplant of a minicom onto the development Board. This allows the serial port to send and receive directly. Especially when I need to test multiple serial ports at the same time, faster than writing programs. No more nonsense, look at the operation flow be

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.

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
