According to the characteristics of MECHATROLINK, the thesis designs and implements a device driver layer between motion controller and filebus.
根据MECHATROLINK现场总线的特点，本文设计并实现了运动控制器与MECHATROLINK总线之间的设备驱动层。
Examples of devices at this layer include the SLIP driver over a serial interface or an Ethernet driver over an Ethernet device.
例如，包串口使用的SLIP驱动程序以及以太网设备使用的以太网驱动程序都是这一层的设备。
Therefore, the Linux USB layer, the BlueZ USB transport driver, and the BlueZ protocol stack are the main kernel layers that get the device working.
因此，LinuxUS b层、BlueZ US b传输器驱动程序以及BlueZ协议栈是使设备工作的主要内核层。
"Function driver" is a device of dependent file. Different card needs specific "function driver" which assures any card is same to API layer.
“函数驱动层”是一个硬件相关的文件，不同的采集卡需要不同的“函数驱动层”，它们保证不同的卡对api层的一致性。
You might also choose to implement a monolithic driver if the capabilities of your device are well matched to the tasks that the functions in the MDD layer perform.
如果你的设备的功能与MDD层功能函数非常一致，你也可以将驱动实现为单体。
The device Abstract Layer provides a set of standard communication interface functions unrelated with specific device, which is mapped to device drivers by file table, device table and driver table.
设备抽象层为上层应用程序提供了一套标准的、与设备无关的通信接口，并且通过文件描述表、设备描述表和驱动描述表建立了从通信接口到设备驱动的映射。
From bottom to top, the system is plotted out bus driver layer, device function driver layer, communication layer and user-interface. Each layer provides service to the layer above by interface style.
由下往上将整个驱动软件系统分为总线驱动层、设备功能驱动层、通信层和用户界面等层次，每一层都以接口的形式为上层提供服务。
Simultaneously, the device driver interacts with the up layer software, and provides services for them.
同时，第三层交换机的驱动程序还要与上层软件交互，为上层软件提供服务。
The upper layer is also known as the model device driver (MDD), and the lower layer is also known as the platform dependent driver (PDD).
上层通常被叫做模型设备驱动(MDD)，下层通常被叫做平台相关驱动(PDD)。
USB Function device driver is designed by client, it lies the up layer of USB Bus device driver, it sends and receives information from USB device by send URB to USB Bus device driver.
USB功能驱动程序由设备开发者编写，位于USB总线驱动程序的上层，通过向USB总线驱动程序发送USB请求包，来实现对USB设备信息的发送或接收。
