This includes the project using a stereo vision to catch the ball shot from a high pressure air cannon. The trajectory of the ball is located first by finding the ball color in the left and right camera. Then the trajectory is calculated to estimate the depth from the ball to the camera. The camera is calibrated to map the world coordinate to the camera coordinate and it can reach an accuracy over 90 . Enjoy

Verilog Coding Style for Efficient Digital Design

In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding guidelines are followed. Discussion of all the techniques is beyond the scope of this paper, however,here we try to cover a few of them.

IC封裝熱計算研究

Many thermal metrics exist for integrated circuit (IC) packages ranging from θja to Ψjt.Often, these thermal metrics are misapplied by customers who try to use them to estimate junction temperatures in their systems.

ICCAVR 入門

ICCAVR簡介ICCAVR 是一種使用ANSI 標準C 語言來開發微控制器（MCU）程序的一個工具，它是一個綜合了編輯器和工程管理器的集成工作環境（IDE）。源文件全部被組織到工程之中，文件的編輯和工程（project）的構筑也在IDE 的環境中完成。編譯錯誤在狀態窗口中顯示，用鼠標單擊編譯錯誤時，光標會自動跳轉到出錯行。這個工程管理器還能直接產生INTEL HEX格式的燒寫文件和可以在AVR Studio 中調試的COFF 格式的調試文件。這里特別要提一下ICCAVR 中的應用構筑向導，可以在Tools 欄中選擇“ApplicationBiulder”或者直接點擊快捷工具欄中的“Application Biulder”圖標，就可以打開應用構筑向導對話框，可以根據需要設定芯片種類，各個端口初始值，是否使用定時器，中斷，UART等，選好以后單擊“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。圖1給出了初始化UART 的一個例子：下面介紹一下創建并編譯一個工程文件的簡要步驟：1．新建一個源文件從file 菜單中選擇new，創建一個新文件，在改文件中輸入源程序并進行編輯和修改，然后存盤，在存盤時必須指定文件類型，如命名為：try.c 。寫一個新文件的步驟：首先用Biulder 初始化需要用到的硬件資源，生成初始化程序，然后再寫需要的代碼實現所要的功能。2．新建一個project從projrct 菜單中選擇new 命令，IDE 會彈出一個對話框，在對話框中用戶可以指定工程存放的文件夾和工程的名稱。在建立一個新工程之后，在工程管理器的窗口會出現三個子目錄，Files, Headers, Documents,這時就可以將要編譯的文件添加到project 中了。3．把文件添加到工程中可以在project-files 里單擊右鍵，選擇需要添加的文件；也可以在編輯窗口中單擊右鍵選擇彈出窗口的“Add To Project”命令。4．編譯源文件在編譯之前特別要注意在Project Options 中選擇與硬件相應的芯片。如本次實驗就選擇ATMEGA8515,如圖2 所示。在project 中選擇make project,也可以直接單擊快捷鍵F9，這時要是有錯則會彈出出錯信息，修改調試正確以后單擊快捷鍵ISP 就可以燒寫到硬件中去了。

I2C slave routines for the 87L

The 87LPC76X Microcontroller combines in a small package thebenefits of a high-performance microcontroller with on-boardhardware supporting the Inter-Integrated Circuit (I2C) bus interface.The 87LPC76X can be programmed both as an I2C bus master, aslave, or both. An overview of the I2C bus and description of the bussupport hardware in the 87LPC76X microcontrollers appears inapplication note AN464, Using the 87LPC76X Microcontroller as anI2C Bus Master. That application note includes a programmingexample, demonstrating a bus-master code. Here we show anexample of programming the microcontroller as an I2C slave.The code listing demonstrates communications routines for the87LPC76X as a slave on the I2C bus. It compliments the program inAN464 which demonstrates the 87LPC76X as an I2C bus master.One may demonstrate two 87LPC76X devices communicating witheach other on the I2C bus, using the AN464 code in one, and theprogram presented here in the other. The examples presented hereand in AN464 allow the 87LPC76X to be either a master or a slave,but not both. Switching between master and slave roles in amultimaster environment is described in application note AN435.The software for a slave on the bus is relatively simple, as theprocessor plays a relatively passive role. It does not initiate bustransfers on its own, but responds to a master initiating thecommunications. This is true whether the slave receives or transmitsdata—transmission takes place only as a response to a busmaster’s request. The slave does not have to worry about arbitrationor about devices which do not acknowledge their address. As theslave is not supposed to take control of the bus, we do not demandit to resolve bus exceptions or “hangups”. If the bus becomesinactive the processor simply withdraws, not interfering with themaster (or masters) on the bus which should (hopefully) try toresolve the situation.
