Accurate measurement of the third order intercept pointfor low distortion IC products such as the LT5514 requirescertain precautions to be observed in the test Setup andtesting procedure. The LT5514 linearity performance ishigh enough to push the test equipment and test Set-up totheir limits. A method for accurate measurement of thirdorder intermodulation products, IM3, with standard testequipment is outlined below.It is also important to correctly interpret the LT5514specification with respect to ROUT, and the impact ofdemo-board transmission-line termination loss whenevaluating the linearity performance, as explained in theLT5514 Datasheet and in Note 1 of this document.

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); }

介紹幾種cpuThe 8xC251SA/SB/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture i.e., the MCS 251 microcontroller architecture. The register based CPU supports a 40-byte register file. In addition, the 8xC251SA/SB/SP/SQ microcontroller has 256-Kbyte expanded external code/data memory space and 64-Kbyte stack space. The new controller is also specially designed to execute C code efficiently. More importantly, the 8xC251SA/SB/SP/SQ maintains binary code compatibility with MCS 51 microcontrollers but at the same time allows the use of the powerful MCS 251 microcontroller instruction Set, with many new 8, 16 and 32 bit instructions available. The 8xC251SA/SB/SP/SQ has 512 bytes or 1 Kbyte of on-chip data RAM options and is available in 16 Kbytes and 8 Kbytes of on-chip ROM/OTPROM or ROMless options.

基于matlab的mp3的讀寫函數Mp3 toolbox for Matlab. Alfredo Fernandez Franco Aalborg University Departament of Acoustics M.Sc. Student aberserk@yahoo.com Includes 2 functions to write and read MP3 files. It works like the commands WAVWRITE and WAVREAD. 1.- Just unpack in the toolbox folder under the MATLAB directory. 2.- Set the MATLAB search path to include that folder. This version was made in MATLAB for WINDOWS only. I ll probably will make the UNIX version later. 01-11-2004.
