The previous chapters mainly describe the installation and construction of the native Linux Android development environment and the porting of the Android system. This chapter focuses on how to install Android on the Development Board . Development boards are the main hardware devices for developing and learning embed

1. OverviewEmbedded system consists of hardware environment, embedded operating system and application, hardware environment is the hardware platform of operating system and application, it has different requirements depending on the application. The diversity of hardware platform is the main feature of embedded system, how to make the embedded operating system run effectively on different hardware platform is the key problem in the development of emb

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

Bunker Ubuntu Core Linux support TS-4900 Iot Development BoardBunker Ubuntu Core Linux support TS-4900 Iot Development BoardThe biggest advantage of a Linux Kernel Operating System is that it can work on various types of hardware, such as ARM or x86 architecture. In contrast, Microsoft Windows has more restrictions (even if it has a dedicated Windows 10 IoT for ARM ). Among all Linux distributions, Ubuntu i

will have several security prompts, all agree, as shown in6. The driver has been installed successfully.7. 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 software and create a new terminal window as sho

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.

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

The Development Board launched earlier does not have a network port. Therefore, many network-based functions of the. NET micro framework cannot be studied. In the IOT era, network functions are king. In addition to the Ethernet module, the New Development Board also adds the USB Host module and other related interfaces

AC6102 Development Board USB3.0 test and use instructionsOverviewThe AC6102 incorporates a cypress-launched high-performance USB3.0 transmission chip cyusb3014,cypress called EZ-USBFX3. The chip features strong, powerful, simple interface and is ideal for use in a variety of applications where high-speed data transmission is required, following an introduction to the chip from the EZ-USBFX3 data sheet:Cypre

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

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
