Digital cameras have become increasingly popular over the last few years. Digital imagingtechnology has grown to new markets including cellular phones and PDA devices. With thediverse marketplace, a variety of imaging technology must be available. Imaging technologyhas expanded to include both charge-coupled device (CCD) and CMOS image sensors.

UART 4 UART參考設計,Xilinx提供VHDL代碼 uart_vhdl This zip file contains the following folders: \vhdl_source -- Source VHDL files: uart.vhd - top level file txmit.vhd - transmit portion of uart rcvr.vhd - - receive portion of uart \vhdl_testfixture -- VHDL Testbench files. This files only include the testbench behavior, they do not instantiate the DUT. This can easily be done in a top-level VHDL file or a schematic. This folder contains the following files: txmit_tb.vhd -- Test bench for txmit.vhd. rcvr_tf.vhd -- Test bench for rcvr.vhd.

用途:測量地磁方向,測量物體靜止時候的方向,測量傳感器周圍磁力線的方向。注意,測量地磁時候容易受到周圍磁場影響,主芯片HMC5883 三軸磁阻傳感器特點(抄自網上): 1,數字量輸出:I2C 數字量輸出接口,設計使用非常方便。 2,尺寸小: 3x3x0.9mm LCC 封裝,適合大規模量產使用。 3,精度高:1-2 度,內置12 位A/D,OFFSET, SET/RESET 電路,不會出現磁飽和現象,不會有累加誤差。 4,支持自動校準程序,簡化使用步驟,終端產品使用非常方便。 5,內置自測試電路,方便量產測試,無需增加額外昂貴的測試設備。 6,功耗低:供電電壓1.8V, 功耗睡眠模式-2.5uA 測量模式-0.6mA 連接方法: 只要連接VCC,GND,SDA,SDL 四條線。 Arduino GND -> HMC5883L GND Arduino 3.3V -> HMC5883L VCC Arduino A4 (SDA) -> HMC5883L SDA Arduino A5 (SCL) -> HMC5883L SCL (注意,接線是A4,A5,不是D4,D5) 源程序: #include <Wire.h> #include <HMC5883L.h> HMC5883Lcompass; voidsetup() { Serial.begin(9600); Wire.begin(); compass = HMC5883L(); compass.SetScale(1.3); compass.SetMeasurementMode(Measurement_Continuous); } voidloop() { MagnetometerRaw raw = compass.ReadRawAxis(); MagnetometerScaled scaled = compass.ReadScaledAxis(); float xHeading = atan2(scaled.YAxis, scaled.XAxis); float yHeading = atan2(scaled.ZAxis, scaled.XAxis); float zHeading = atan2(scaled.ZAxis, scaled.YAxis); if(xHeading < 0) xHeading += 2*PI; if(xHeading > 2*PI) xHeading -= 2*PI; if(yHeading < 0) yHeading += 2*PI; if(yHeading > 2*PI) yHeading -= 2*PI; if(zHeading < 0) zHeading += 2*PI; if(zHeading > 2*PI) zHeading -= 2*PI; float xDegrees = xHeading * 180/M_PI; float yDegrees = yHeading * 180/M_PI; float zDegrees = zHeading * 180/M_PI; Serial.print(xDegrees); Serial.print(","); Serial.print(yDegrees); Serial.print(","); Serial.print(zDegrees); Serial.println(";"); delay(100); }

赫赫大名的 OGRE 游戲引擎,游戲編程高手特別是游戲引擎高手的最好教材,開源代碼,不看是你的損失。VC.NET編譯交順利,遇到編譯錯誤時添加相應INCLUDE文件,直到通過為止。VC++ 6.0未試過,估計問題較多,祝你好運。

重寫了微軟提供SQLHelper(共用的數據庫調用接口) 1把SqlHelper的connectionString做成一個全局量,統一設置數據庫連接字符串 2增加了返回特定表名的DataSet的各接口。 可在項目的config文件設置數據庫連接字符串 private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"] <!-- application specific settings --> <appSettings> <add key="ConnectionString" value="packet size=4096 user id=sa data source=localhost persist security info=True initial catalog=NorthWind password= "/> </appSettings> 當然可以把數據庫連接方法修改后直接用。
