【摘要】：隨著科學(xué)技術(shù)的快速發(fā)展，當(dāng)今數(shù)字存儲示波器（DSO）性能有著日益顯著的提高，功能亦趨向多樣化、集成化。數(shù)字存儲示波器提供了RS232接口、LAN口、GPIB接口、USB接口等多種接口。其中USB即通用串行總線，這種接口自身有許多優(yōu)點，所以目前已經(jīng)成為數(shù)字存儲示波器的必備接口。 本論文針對具有USB接口的數(shù)字存儲示波器進(jìn)行一系列的軟件開發(fā)。根據(jù)USB主機(jī)從設(shè)備模型，將論文軟件分為以下兩個部分的內(nèi)容： 首先，當(dāng)DSO數(shù)字存儲示波器作為USB設(shè)備接到PC機(jī)上時，開發(fā)PC端針對數(shù)字存儲示波器的功能驅(qū)動程序，使PC機(jī)可以識別該儀器，實現(xiàn)windows下操作該儀器，并編寫windows的控制臺應(yīng)用程序，操作該儀器，驗證驅(qū)動的功能。同時開發(fā)DSO數(shù)字存儲示波器PCB板端的固件程序，配合PC端的驅(qū)動程序?qū)崿F(xiàn)PC機(jī)對設(shè)備的識別、枚舉以及配置操作。 其次，當(dāng)DSO數(shù)字存儲示波器作為USB主機(jī)系統(tǒng)外接存儲介質(zhì)時，開發(fā)示波器主機(jī)端的軟件驅(qū)動程序，主要包括主機(jī)棧程序，可以實現(xiàn)對USB設(shè)備的枚舉配置工作并管理設(shè)備的拔插操作，以及在主機(jī)棧的基礎(chǔ)上開發(fā)大容量類設(shè)備驅(qū)動，傳輸處理層用Bulk-Only傳輸協(xié)議實現(xiàn)，命令塊層用到的指令集是UFI，可以實現(xiàn)主機(jī)系統(tǒng)讀寫UFI設(shè)備的數(shù)據(jù)以及獲取UFI設(shè)備的信息等操作，，然后在此基礎(chǔ)之上添加FAT文件系統(tǒng)，增強(qiáng)主機(jī)對優(yōu)盤文件的管理能力。 本論文的研究符合當(dāng)前數(shù)字存數(shù)示波器的大體發(fā)展趨勢，進(jìn)一步實現(xiàn)了DSO數(shù)字存儲示波器的功能多樣化，對于數(shù)字示波器的進(jìn)一步研發(fā)具有積極意義。
[Abstract]:With the rapid development of science and technology, the performance of DSO (Digital Storage Oscilloscope) has been improved day by day, and the functions are becoming diversified and integrated. Digital storage oscilloscope provides RS232 interface LAN interface GPIb interface USB interface and other interfaces. USB is the universal serial bus, this interface has many advantages, so it has become a necessary interface for digital storage oscilloscope. This paper develops a series of software for digital storage oscilloscope with USB interface. According to USB host slave device model, the thesis software is divided into the following two parts: first, when DSO digital storage oscilloscope is connected to PC as USB device, The function driver of PC for digital storage oscilloscope is developed, so that PC can recognize the instrument, realize the operation of the instrument under windows, write the windows console application program, operate the instrument and verify the function of the driver. At the same time, the firmware program of PCB board of DSO digital storage oscilloscope is developed, and the device identification, enumeration and configuration operation are realized with the driver of PC. Secondly, when the DSO digital storage oscilloscope is used as the external storage medium of USB host system, the software driver of the host terminal of the oscilloscope is developed, which mainly includes the host stack program. It can realize the enumeration and configuration of USB devices and manage the device pull-in operation, and develop a large capacity device driver on the basis of host stack. The transport processing layer is realized by Bulk-Only transport protocol. The instruction set used in the command block layer is UFI, which can read and write the data of UFI device and obtain the information of UFI device. Then, the fat file system is added on this basis to enhance the host's ability to manage the USB disk file. The research in this paper accords with the general development trend of the digital storage oscilloscope at present, and further realizes the function diversification of the DSO digital storage oscilloscope, which has positive significance for the further research and development of the digital oscilloscope.
