基于USB的高清彩色CCD圖像采集系統(tǒng)

提出一種基于USB的彩色CCD高清圖像采集系統(tǒng)設(shè)計方案。圖像數(shù)據(jù)的來源采用的是SONY公司的 ICX205AK芯片，結(jié)合USB2.0接口，復(fù)雜可編程邏輯器件CPLD設(shè)計了一個高速的彩色CCD圖像采集系統(tǒng)。文中詳細(xì)闡述了系統(tǒng)內(nèi)不同模塊的硬件電路設(shè)計思路和軟件運(yùn)行流程。整個系統(tǒng)由電源系統(tǒng)、CCD傳感器、A/D模數(shù)轉(zhuǎn)換器、CPLD控制器、USB2.0高速接口、上位機(jī)控制程序等各個部分組成。本系統(tǒng)的硬件電路可以協(xié)調(diào)正常工作完成分辨率為140萬的高清圖像采集，最高采集幀率達(dá)7.5 Frame/s。

屏蔽夾廠家資料

一般有使用到無線通信的產(chǎn)品，通常都會在電路板上設(shè)計屏蔽框(shielding Frame)來隔絕電磁干擾(EMI)，現(xiàn)在有些腦筋動得快的廠商想出了使用夾子(clip)來取代屏蔽框的方法，這種夾子不但可以使用SMT打件，而且體積小所以不怕變形。這就是傳說中的屏蔽夾了。

基于MC9S12HZ256的總線式汽車數(shù)字儀表設(shè)計

首先研究CAN總線和SAE J1939協(xié)議，提出一種基于MC9S12HZ256微控制器的總線式汽車數(shù)字儀表解決方案。詳細(xì)介紹SAE J1939協(xié)議的報文幀格式及應(yīng)用層協(xié)議中發(fā)動機(jī)相關(guān)參數(shù)的定義，以及步進(jìn)電機(jī)及其驅(qū)動和車速信號的處理方法。該數(shù)字儀表系統(tǒng)硬件平臺由微處理器和信號采集和信息處理及顯示等模塊組成。軟件設(shè)計部分編程實現(xiàn)了對CAN總線和各傳感器數(shù)據(jù)的讀取、處理。該系統(tǒng)能夠?qū)崟r反映車輛工況。 Abstract: In this paper，CAN bus and SAE J1939protocol are researched，and a vehicle digital instrument solution based on MC9S12HZ256MCU is proposed.The message Frame format and some engine-related parameters’definition in SAE J1939application layer protocol are introduced in detail.Stepper motor and its driver，the methods of speed signal process-ing are also introduced.The hardware platform of vehicle digital instrument is composed by MCU，signal acquisition mod-ule，and signal processing and displaying module.Data receiving and processing from CAN bus and sensors are accom-plished by programming，and vehicle condition can be reflected in real-time.

基于CAN總線的綜自通訊規(guī)約設(shè)計

介紹一種基于CAN總線的牽引變電站自動化系統(tǒng)通訊規(guī)約的設(shè)計，CAN通訊規(guī)約采用標(biāo)準(zhǔn)幀，報文采用主動發(fā)送和發(fā)送查詢兩種處理形式。該設(shè)計在城市輕軌與地鐵牽引變電站中的應(yīng)用表明：可實現(xiàn)間隔層和通訊處理層的數(shù)據(jù)快速、可靠的交換，提高牽引變電站的安全性和穩(wěn)定性。 Abstract: This paper firstly presents a kind of design dealing with communicational protocol to the traction substation automation system based on CAN bus,and then comes up with the ideas that all Frames of CAN communicational protocol should adopt the standard Frame,and that messages be processed by two ways:sending initiatively and sending quiries.Subway and light rail application shows that the use of the CAN bus is possible to exchange data quickly and reliably between the layers of the middle and the communicational processing,hence to improve the safety and stability of traction substations.

LPC1700以太網(wǎng)MIIM接口應(yīng)用筆記

The LPC1700 Ethernet block contains a full featured 10 Mbps or 100 Mbps Ethernet MAC (Media Access Controller) designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control Frames, hardware acceleration for transmit retry, receive packet filtering and wake-up on LAN activity. Automatic Frame transmission and reception with Scatter-Gather DMA off-loads many operations from the CPU.
