This software is developed to provide ease with controller design. For PID control, optionS are given to design and analyse the compensated and uncompensated system. You are free to choice among Proportional PI, PD and PID mode of control. Both frequency and time domain characteristics can be observed. Special Menus are given to observe time and frequency response plots. For Statefeedback controller similar optionS are given. But this is limited to second order system only.

The MAX17600–MAX17605 devices are high-speedMOSFET drivers capable of sinking /sourcing 4A peakcurrents. The devices have various inverting and noninvertingpart optionS that provide greater flexibility incontrolling the MOSFET. The devices have internal logiccircuitry that prevents shoot-through during output-statchanges. The logic inputs are protected against voltagespikes up to +14V, regardless of VDD voltage. Propagationdelay time is minimized and matched between the dualchannels. The devices have very fast switching time,combined with short propagation delays (12ns typ),making them ideal for high-frequency circuits. Thedevices operate from a +4V to +14V single powersupply and typically consume 1mA of supply current.The MAX17600/MAX17601 have standard TTLinput logic levels, while the MAX17603 /MAX17604/MAX17605 have CMOS-like high-noise margin (HNM)input logic levels. The MAX17600/MAX17603 are dualinverting input drivers, the MAX17601/MAX17604 aredual noninverting input drivers, and the MAX17602 /MAX17605 devices have one noninverting and oneinverting input. These devices are provided with enablepins (ENA, ENB) for better control of driver operation.

For a variety of reasons, it is desirable to charge batteriesas rapidly as possible. At the same time, overchargingmust be limited to prolong battery life. Such limitation ofovercharging depends on factors such as the choice ofcharge termination technique and the use of multi-rate/multi-stage charging schemes. The majority of batterycharger ICs available today lock the user into one fixedcharging regimen, with at best a limited number ofcustomization optionS to suit a variety of application needsor battery types. The LTC®1325 addresses these shortcomingsby providing the user with all the functionalblocks needed to implement a simple but highly flexiblebattery charger (see Figure 1) which not only addressesthe issue of charging batteries but also those of batteryconditioning and capacity monitoring.

CCAVR软件有ISP功能，能过调用STK500完成的，只要设置好参数，在ICCAVR中就可以给芯片编程了，还可以让程序一编译完就自动下载到芯片中，相当方便。在Tools->environment optionS->ISP里设定STK500.exe的路径。— 用于调用STK500程序。在Tools->In system programming 里Programmer Interface中选中STK500。— 选择STK500下载方式。在Tools->In system programming 里把Auto Program After Compile 的小勾选上。— 编译后自动编程。在Tools->In system programming 中还有一些设置项，大家可以根据需要进行相关设置。下面的图片是操作过程。

ICCAVR简介ICCAVR 是一种使用ANSI 标准C 语言来开发微控制器（MCU）程序的一个工具，它是一个综合了编辑器和工程管理器的集成工作环境（IDE）。源文件全部被组织到工程之中，文件的编辑和工程（project）的构筑也在IDE 的环境中完成。编译错误在状态窗口中显示，用鼠标单击编译错误时，光标会自动跳转到出错行。这个工程管理器还能直接产生INTEL HEX格式的烧写文件和可以在AVR Studio 中调试的COFF 格式的调试文件。这里特别要提一下ICCAVR 中的应用构筑向导，可以在Tools 栏中选择“ApplicationBiulder”或者直接点击快捷工具栏中的“Application Biulder”图标，就可以打开应用构筑向导对话框，可以根据需要设定芯片种类，各个端口初始值，是否使用定时器，中断，UART等，选好以后单击“OK”就可以得到所需的硬件初始化程序段，非常可靠而且方便。图1给出了初始化UART 的一个例子：下面介绍一下创建并编译一个工程文件的简要步骤：1．新建一个源文件从file 菜单中选择new，创建一个新文件，在改文件中输入源程序并进行编辑和修改，然后存盘，在存盘时必须指定文件类型，如命名为：try.c 。写一个新文件的步骤：首先用Biulder 初始化需要用到的硬件资源，生成初始化程序，然后再写需要的代码实现所要的功能。2．新建一个project从projrct 菜单中选择new 命令，IDE 会弹出一个对话框，在对话框中用户可以指定工程存放的文件夹和工程的名称。在建立一个新工程之后，在工程管理器的窗口会出现三个子目录，Files, Headers, Documents,这时就可以将要编译的文件添加到project 中了。3．把文件添加到工程中可以在project-files 里单击右键，选择需要添加的文件；也可以在编辑窗口中单击右键选择弹出窗口的“Add To Project”命令。4．编译源文件在编译之前特别要注意在Project optionS 中选择与硬件相应的芯片。如本次实验就选择ATMEGA8515,如图2 所示。在project 中选择make project,也可以直接单击快捷键F9，这时要是有错则会弹出出错信息，修改调试正确以后单击快捷键ISP 就可以烧写到硬件中去了。

The main oscillator allows either a crystal or single-ended input clock signal. Cost-sensitiveapplications typically use an external crystal with the on-chip oscillator circuit since it is the mostcost-effective solution. It is also possible to use the internal oscillator to clock the device after theboot process has completed.

The Philips family of Multiplexers and Switches consists of bi-directional translating switches controlled via the I2C or SMBus to fan out an upstream SCL/SDA pair to 2, 4 or 8 downstream channels of SCx/SDx pairs. The Multiplexers allow only one downstream channel to be selected at a time, while the Switches allow any individual downstream channel or combination of downstream channels to be selected, depending on the content of the programmable control register. Once one or several channels have been selected, the device acts as a wire, allowing the master on the upstream channel to send commands to devices on all the active downstream channels, and devices on the active downstream channels to communicate with each other and the master. External pull-up resistors are used to pull each individual channel up to the desired voltage level. Combined interrupt output and hardware reset input are device optionS that are featured.
