firmware program design mainly shows the step of development and flowchart with corresponding code segment 固件程序设计主要说明开发的步骤和流程图,并辅以相应的代码段。
Then it describes usb driver and firmware programming . particular design is given by several specific program examples 通过分析具体的程序例子给出了详细的程序设计思路和具体的程序流程图。
After that, this paper depicts the software design for ccd camera system, including the usb device driver and firmware program 此外,对系统的软件设计给予了详细的说明,包括usb2.0接口的主机驱动程序、固件程序的开发。
In my practise stage, i design the usb transformation models with usb-rs232 module and usb-cf module, and finish the relevant circuit designs and firmware programming 在设计的实现阶段,完成了相关的电路设计和固件编程,实现了具有usb_rs232、usb_cf转换模块的usb复合设备。
Be superior to firmware program developed in assemble language traditionally, our program is completed by c language, which improves program's movable and legibility 与传统的用汇编语言开发固件程序有所不同,我们所有代码均以c语言完成,既提高了程序的可移植性又增强了程序的易读性。
In addition, it also embodies the high date-transmission speed of usb software design consists of writing the firmware program of usb controller and developing drive program based on windows operating system 3.编写了usb总线控制器的固件程序和基于windows操作系统平台的驱动程序。固化在控制器中的固件代码能在上电后自动完成usb设备的配置与初始化,并提供总线工作的数据传输中断服务。
This project includes three parts concerning hardware : lcm application circuit, arm system periphery circuit and usb interface circuit; also includes three parts concerning software : the firmware program of micro-controller, usb device driving program, and upper application 系统的硬件部分有:lcm应用接口电路、arm系统外围电路和usb接口电路。系统的软件部分有:微控制器固件程序、usb设备驱动程序和上层应用程序。
In the design of software, this paper stress the usb system drive archecture and the idea of firmware programming . based on wdm drive programming thinking, give an example of usb device drive . under the environment of visual c + + 6.0, adopt the idea of object-orientation, modular design and multithreading to finish the development of user application, including the function of operation interface, usb device attachment, wave display, parameter read / write, document printing and saving 软件方面,重点介绍了usb系统驱动体系以及固件编程思想。基于wdm驱动程序思想,给出了usb设备驱动程序的编程实例。pc机在visualc++6.0编程环境下,利用面向对象、模块化程序设计思维和多线程的方法,完成用户应用程序,包括操作界面、usb设备连接、波形显示、参数读取、文件打印存储等功能。
