-Upload---> Development Board)The PC sends a file to the Development Board. The file to be sent is in the/tmp directory (the directory on the PC ). After this configuration, each time you send a file to the Development BoardYou only need to enter the file name, without entering the absolute path of the directory where the file is located. Iii.

integrated to achieve the goal of driving. Ddsi refers to the interface between these two parts. This interface is not subject to mandatory physical/logical relationships, but is manually defined. When a specific hardware is involved, we often need to understand the physical characteristics and control logic of the hardware, and then implement it according to the constraints of ddsi. The key to combining the driver model described here is the use and

Author: Dong Yuxin, Zhang Donglai Source: Micro-Computer Information1. Introduction Hardware driver development is the foundation of embedded development. With the popularization of USB devices, the development of USB device drivers has become increasingly important in embedded development. To support different types of platform peripherals that can be connected

Analysis of USB 2.0 Driver Based on VxW0rks [Date:] Source: World of electronic products Author: [Font: large, medium, and small] 　 Introduction Universal Serial bus is a computer peripheral serial communication interface, featuring high-speed data transmission, hot swapping, plug-and-play (PnP),

Linux supports the connection of various USB slave devices while also supporting itself as a device into other hosts. The most typical example is the Android OS phone, which plugs into a computer that can be identified as a USB stick device. For the SOC, this part directly corresponds to the operation of the USB device section. To avoid confusion with the word "d

Windows CE, as a typical embedded operating system, is typical for other embedded systems such as PSOs + and nucleus us by porting Bluetooth applications to widows ce. Because the file transmission application on obex is built on the Bluetooth simulation serial port of RFCOMM implementation, this article introduces the implementation of the Bluetooth virtual serial port
