The purpose of this document is to present how to use the Timer for the generation of a PWM signal tunable in frequency and duty cycle. As an application example, this document is based on a basic “music” synthesizer through an external buzzer. Example code is also available in the it.

1、该PERIPHERAL文件夹包含五个有关系统外设的程序:DEC5502_USB、DEC5502_LED和DEC5502_UART程序。 2、DEC5502_USB程序主要实现了与PC机应用程序之间的USB通讯,并根据PC机传来的指令进行相应的动作。 3、DEC5502_UART程序主要完成了利用外扩UART(A通路和B通路)与PC机进行数据的发送和接收操作。 4、DEC5502_LED程序通过配置系统定时器和系统中断来控制指示灯D5和D1,并且通过D5和D1是否交替闪烁来达到测试系统定时器和系统中断的目的。 5、DE5502_SDRAM与EMIF有关的测试程序。对他们的访问成功与否主要取决于对EMIF接口的配置,测试程序配置时设为最为可靠的方式,用户可以根据相应的技术文档来对EMIF进行重新配置,从而提高访问外扩存储器的速度。

This paper presents a visual based localization mechanism for a legged robot. Our proposal, fundamented on a probabilistic approach, uses a precompiled topological map where natural landmarks like doors or ceiling lights are recognized by the robot using its on-board camera. Experiments have been conducted using the AIBO Sony robotic dog showing that it is able to deal with noisy sensors like vision and to approximate world models representing indoor ofce environments. The two major contributions of this work are the use of this technique in legged robots, and the use of an active camera as the main sensor

fwknop stands for "Firewall Knock Operator" and is an upcoming piece of software that will be released at the DEFCON 12 conference in July, 2004 in Las Vegas. fwknop implements network access controls (via iptables) based on a flexible port knocking mini-language, but with a twist it combines port knocking and passive operating system fingerprinting to make it possible to do things like only allow, say, Linux-2.4/2.6 systems to connect to your SSH daemon. fwknop supports shared, multi-protocol port knock sequences along with both relative and absolute timeouts, and coded port knock sequences encrypted with the Rijndael block cipher.

Cfingerd is a free and secure finger daemon replacement for standard finger daemons such as GNU fingerd or MIT fingerd. It can enable/disable finger service to individual users, rather than to all users on a given host.

CAN1.c and CAN2.c are a simple example of configuring a CAN network to transmit and receive data on a CAN network, and how to move information to and from CAN RAM message objects. Each C8051F040-TB CAN node is configured to send a message when it s P3.7 button is depressed/released, with a 0x11 to indicate the button is pushed, and 0x00 when released. Each node also has a message object configured to receive messages. The C8051 tests the received data and will turn on/off the target board s LED. When one target is loaded with CAN2.c and the other is loaded with CAN1.c, one target board s push-button will control the other target board s LED, establishing a simple control link via the CAN bus and can be observed directly on the target boards.

本题要完成的是一组简单C表达的运算。所有表达式存放在文件 CExpression.txt 中,每个表达式一行。每行的长度不会超过80个字符。文件最后有一个空行表示结束。 每个表达式,只包含简单的整数变量和限定的一些操作符,表达式中没有常量。总共有26个可能出现在表达式中的变量,分别命名为 a,b,...,z。每个变量最多出现一次。26个变量的初值分别为1,2,...,26。 表达式中的操作符,包括:两个二元操作符 +, -,表示加,减运算。例如,表达式a+c-d+b(即1+3-4+2)的结果为2。 单独一个-号不能放在变量前面,表示负数。 表达式中还包含两个一元运算符:++,--,表示加一和减一运算。它们既可以出现在一个变量的前面、也可以出现在后面。如果出现在变量前面,则表示先对变量进行加一/减一运算,然后变量值参与表达式计算。如果出现在变量后面,则表示变量的原值参与表达式计算,表达式计算完之后,变量值加一/减一。 例如,表达式 -- c + b-- 的结果为 4, 表达式计算完之后, b,c的值分别为1,2 输出格式要求:输出直接显示在屏幕上。对于每个表达式,第一行输出表达式的内容。第二行输出表达式的值,后面几行输出参与运算的各个变量的结果值。
