Automobiles, aircraft, marine vehicles, uninterruptiblepower supplies and telecom hardware represent areasutilizing series connected battery stacks. These stacksof individual cells may contain many units, reaching potentialsof hundreds of volts. In such systems it is oftendesirable to accurately determine each individual cell’svoltage. Obtaining this information in the presence of thehigh “common mode” voltage generated by the batterystack is more diffi cult than might be supposed.

SL811開(kāi)發(fā)資料_包含源程序_電路圖_芯片資料:SL811HS Embedded USB Host/Slave Controller.The SL811HS is an Embedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB peripherals. The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers.The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUs and many others. Internally,the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.

基本的編輯工具(GENERAL EDITING FACILITIES) 對(duì)象放置(Object Placement) ISIS支持多種類(lèi)型的對(duì)象,每一類(lèi)型對(duì)象的具體作用和功能將在下一章給出。雖然類(lèi)型不同,但放置對(duì)象的基本步驟都是一樣的。 放置對(duì)象的步驟如下(To place an object:) 1.根據(jù)對(duì)象的類(lèi)別在工具箱選擇相應(yīng)模式的圖標(biāo)(mode icon)。 2. Select the sub-mode icon for the specific type of object. 2、根據(jù)對(duì)象的具體類(lèi)型選擇子模式圖標(biāo)(sub-mode icon)。 3、如果對(duì)象類(lèi)型是元件、端點(diǎn)、管腳、圖形、符號(hào)或標(biāo)記,從選擇器里(selector)選擇你想要的對(duì)象的名字。對(duì)于元件、端點(diǎn)、管腳和符號(hào),可能首先需要從庫(kù)中調(diào)出。 4、如果對(duì)象是有方向的,將會(huì)在預(yù)覽窗口顯示出來(lái),你可以通過(guò)點(diǎn)擊旋轉(zhuǎn)和鏡象圖標(biāo)來(lái)調(diào)整對(duì)象的朝向。 5、最后,指向編輯窗口并點(diǎn)擊鼠標(biāo)左鍵放置對(duì)象。對(duì)于不同的對(duì)象,確切的步驟可能略有不同,但你會(huì)發(fā)現(xiàn)和其它的圖形編輯軟件是類(lèi)似的,而且很直觀。 選中對(duì)象(Tagging an Object) 用鼠標(biāo)指向?qū)ο蟛Ⅻc(diǎn)擊右鍵可以選中該對(duì)象。該操作選中對(duì)象并使其高亮顯示,然后可以進(jìn)行編輯。

This program demonstrates how to do disconnected briefcase applications with ADO. When the Connected checkbox is unchecked the application is switched into offline mode. If the application is exited at that point then the data is persisted to a file on disk (along with any edits to the data). When the application is restarted it will load the persisted data if present, otherwise it will fetch the data from the database.
標(biāo)簽: demonstrates applications disconnected Connected
