1. This BSP can support 2443EVT0 board. If you want to use EVT0 BSP, set followings. In smdk2443\smdk2443.bat file set BSP_EVT1=1 -> set BSP_EVT1= In smdk2443\src\inc\bsp_cfg.h file #define EVT1 -> #define EVT0 2. Default system tick mode is changed. The value is fixed tick. Fixed tick means that tick interrupt is occurred every 1ms. Variable tick means that timer interrupt period is changed when power mode is in idle. For changing to variable tick In smdk2443\src\inc\bsp_cfg.h file #define FIXEDTICK -> #define VARTICK In smdk2443\src\Common\Timer\Sources file SOURCES= timer_fixedtick.c watchdog.c -> SOURCES= timer_vartick.c watchdog.c

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.

Tiny Planet is small device connected to a GSM cell phone. When the mobile receives a predefined SMS (text message), like "Activate burglar alarm" or "Start backup pump", the circuit automatically recognizes it as a command, and switches the output port accordingly. Besides switching the port on or off, the user can pulse it for a short period (e.g. 鈥淩eboot remote server鈥?.

The objective is to set up SPI communication between VTI Technologies digital pressure sensor component and an MCU of an application device ATMEGA16L. In this code example: ?The MCU is configured ?SCP1000-D01 is initialized and configured ?The high resolution measurement mode is activated ?Temperature and pressure information is read always when the DRDY pin is in high state Please refer to the document "SCP1000 Product Family Specification 8260800" for further information on SCP1000 register addressing and SPI communication. This document applies to the SCP1000-D01.

DES工作的基本原理是，其入口参数有三个:key、data、mode。 key为加密解密使用的密钥，data为加密解密的数据，mode为其工作模式。当模式为加密模式时，明文按照64位进行分组，形成明文组，key用于对数据加密，当模式为解密模式时，key用于对数据解密。实际运用中，密钥只用到了64位中的56位，这样才具有高的安全性。
