為提升虛擬儀器傳輸速率與實(shí)時(shí)性能,擴(kuò)展監(jiān)測范圍,在VC的軟件平臺上設(shè)計(jì)了一種全功能虛擬示波器。與傳統(tǒng)虛擬示波器相比,該系統(tǒng)采用嵌入式系統(tǒng)完成信號采集,采用工業(yè)以太網(wǎng)為傳輸介質(zhì),通過線性插值算法和多線程編程思想,實(shí)現(xiàn)波形顯示、參數(shù)計(jì)算、頻譜分析以及波形存儲及回放功能。實(shí)驗(yàn)結(jié)果表明,該虛擬示波器可以實(shí)現(xiàn)20 kHz采樣頻率下的波形精確顯示,達(dá)到預(yù)期的各項(xiàng)指標(biāo)。 Abstract: o enhance the transfer rate and real-time of virtual instrument performance, expand scope of monitoring, this paper uses the VCs software platform to design a fully functional virtual oscilloscope. Compared with traditional virtual oscilloscope, this system adopts the embedded system to complete the data acquisition, industrial Ethernet as the transmission medium used by the linear interpolation algorithm and multi-threaded programming ideas, namely to achieve waveform display, parameter calculation, spectrum analysis and waveform storage and playback. Experimental results show that the virtual oscilloscope can accurately display the waveform with 20kHz sampling frequency, and achieve the desired targets.

This software aims to create an applet and panel tools to manage a wireless interface card, such as IEEE 802.11 cards. The development will focus on Linux, as this is the most accessible platform, but will expand as we get access to more platforms

About: Paco (pacKAGE oRGANIZER) is a simple, yet powerful tool to aid package management when installing programs from source code. It uses the LD_PRELOAD method to track package installations, and provides various options to keep the installed software organized. It s mainly a command line application but it has also an optional GTKMM interface. Release focus: Minor bugfixes Changes: Libpaco-log has been rewritten in C. This prevents a glibc installation failure when building LFS in chapter 6. The option -x|--expand has been removed. Several bugs have been fixed in paco, gpaco, and rpm2paco. Author: David Rosal

This the second tutorial of the Writing Device Drivers series. There seems to be a lot of interest in the topic, so this article will pick up where the first left off. The main focus of these articles will be to build up little by little the knowledge needed to write device drivers. In this article, we will be building on the same example source code used in part one. In this article, we will expand on that code to include Read functionality, Handle Input/Ouput Controls also known as IOCTLs, and learn a bit more about IRPs.

To use the ATLTrace tool: Debug an MFC or ATL project select Start from the Debug menu. Select MFC/ATL Trace Tool in the Tools menu. expand the tree control list in the Trace List window. Here you will see the running application, any modules within that application, and the trace categories for each module. Customize, for each process, module, and category, which information is displayed in the output window. The Trace level control in the Process group is related to the ATLTRACE2 level only those ATLTRACE2 messages with a level equal to or greater than the setting in the Trace level control will be displayed in the output window. Select Apply to put your settings into effect. You can save your settings, and load them the next time you debug the application use the Save and Load buttons.

The DSKs or eZdspTM LF2407 and the DMC1500 make up a table top motor development system which allows engineers and software developers to evaluate certain characteristics of the TMS320F240, TMS320F243, and TMS320LF2407 DSPs to determine if the processor meets the designers application requirements. Evaluators can create software to execute onboard or expand the system in a variety of ways.
