  • lpc2292/lpc2294 pdf datasheet

    The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct with minimal performance penalty. With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available fast GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary.

  • We have a group of N items (represented by integers from 1 to N), and we know that there is some tot

    We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

  • This tutorial presents an introduction to Altera’s Nios R II processor, which is a soft processor

    This tutorial presents an introduction to Altera’s Nios R II processor, which is a soft processor that can be in- stantiated on an Altera FPGA device. It describes the basic architecture of Nios II and its instruction set. The NiosII processor and its associated memory and peripheral components are easily instantiated by using Altera’s SOPCBuilder in conjuction with the Quartus R II software.

  • 【问题描述】 在一个N*N的点阵中

    【问题描述】 在一个N*N的点阵中,如N=4,你现在站在(1,1),出口在(4,4)。你可以通过上、下、左、右四种移动方法,在迷宫内行走,但是同一个位置不可以访问两次,亦不可以越界。表格最上面的一行加黑数字A[1..4]分别表示迷宫第I列中需要访问并仅可以访问的格子数。右边一行加下划线数字B[1..4]则表示迷宫第I行需要访问并仅可以访问的格子数。如图中带括号红色数字就是一条符合条件的路线。 给定N,A[1..N] B[1..N]。输出一条符合条件的路线,若无解,输出NO ANSWER。(使用U,D,L,R分别表示上、下、左、右。) 2 2 1 2 (4,4) 1 (2,3) (3,3) (4,3) 3 (1,2) (2,2) 2 (1,1) 1 【输入格式】 第一行是数m (n < 6 )。第二行有n个数,表示a[1]..a[n]。第三行有n个数,表示b[1]..b[n]。 【输出格式】 仅有一行。若有解则输出一条可行路线,否则输出“NO ANSWER”。

  • To write data to the FIFO, present the data to be written and assert the write enable. At the next r

    To write data to the FIFO, present the data to be written and assert the write enable. At the next rising edge of the clock, the data will be written. For every rising edge of the clock that the write enable is asserted, a piece of data is written into the FIFO. If the FIFO has data in it, the value at the head of the FIFO is present on the FIFO data output. To read data from the FIFO, assert the read enable. At the next rising edge of the clock, capture the data output the FIFO will subsequently advance to the next piece of data stored in the FIFO.

  • samba服务器实验指导

    第一节、samba是干什么的?它有什么用? Samba(SMB是其缩写) 是一个网络服务器,它是Linux作为本地服务器最重要的一个服务,用于Linux和Windows共享文件之用;Samba可以用于Windows和 Linux之间的共享文件,也一样用于Linux和Linux之间的共享文件;不过对于Linux和Linux之间共享文件有更好的网络文件系统 NFS,NFS也是需要架设服务器的; 2、安装及服务操作命令 安装samba程序非常简单,使用rpm -q samba查看当前系统是否已经安装了samba软件。 如果没有那就进入光盘,rpm -ivh *samba*.rpm即可。 仔细说下安装的包: samba-common-3.0.28-0.el5.8    //samba服务器和客户端中的最基本文件 samba-3.0.28-0.el5.8           //samba服务器核心软件包 system-config-samba-1.2.39-1.el5     //samba图形配置界面 samba-client-3.0.28-0.el5.8          //samba客户端软件   启动、暂停和停止服务: /etc/init.d/smb start /etc/init.d/smb stop /etc/init.d/smb restart 或 service smb start service smb stop service smb restart   第二节、由最简单的一个例子说起,匿名用户可读可写的实现 第一步: 更改smb.conf 我们来实现一个最简单的功能,让所有用户可以读写一个Samba 服务器共享的一个文件夹;我们要改动一下smb.conf ;首先您要备份一下smb.conf文件; [root@localhost ~]# cd /etc/samba [root@localhost samba]# cp smb.conf smb.conf.bak [root@localhost samba]# vi smb.conf 或geidt smb.conf & 然后我们把下面这段写入smb.conf中:   [global] workgroup = WORKGROUP netbios name = Liukai server string = Liukai's Samba Server security = share [test]         path = /opt/test         writeable = yes         browseable = yes         guest ok = yes 注解: [global]这段是全局配置,是必段写的。其中有如下的几行; workgroup 就是Windows中显示的工作组;在这里我设置的是WORKGROUP (用大写); netbios name 就是在Windows中显示出来的计算机名; server string 就是Samba服务器说明,可以自己来定义;这个不是什么重要的; security 这是验证和登录方式,这里我们用了share ;验证方式有好多种,这是其中一种;另外一种常用的是user的验证方式;如果用share呢,就是不用设置用户和密码了; [test] 这个在Windows中显示出来是共享的目录; path = 可以设置要共享的目录放在哪里; writeable 是否可写,这里我设置为可写; browseable 是否可以浏览,可以;可以浏览意味着,我们在工作组下能看到共享文件夹。如果您不想显示出来,那就设置为 browseable=no,guest ok 匿名用户以guest身份是登录; 第二步:建立相应目录并授权 [root@localhost ~]# mkdir -p /opt/test [root@localhost ~]# id nobody uid=99(nobody) gid=99(nobody) groups=99(nobody) [root@localhost ~]# chown -R nobody:nobody /opt/test 注释:关于授权nobody,我们先用id命令查看了nobody用户的信息,发现他的用户组也是nobody,我们要以这个为准。有些系统nobody用户组并非是nobody ; 第三步:启动服务器 第四步:访问Samba 服务器的共享; 1、在Linux 中您可以用下面的命令来访问; [root@localhost ~]# smbclient -L //liukai或 smbclient //192.168.0.94/test Password: 注:直接按回车 2、在Windows中,您可以用下面的办法来访问; \\liukai  或  \\192.168.0.94 3、说明:如果用了netbiosname,就可以用“\\主机名”来访问,如果没用netbiosname,就不能用主机名访问。   第三节、简单的密码验证服务器 修改smb.conf文件: security = user guest account = liukai encrypt passwords = yes smb passwd file = /etc/samba/smbpasswd 然后,建立一个新用户 useradd liukai passwd liukai 成功后,cat /etc/passwd | mksmbpasswd.sh > /etc/samba/smbpasswd smbpasswd -a liukai 这就成功地添加了一个smb用户。 重启服务,使用这个用户进行登录即可。

  • fft analysis

          Use the fast Fourier transform function fft to analyse following signal. Plot the original signal, and the magnitude of its spectrum linearly and logarithmically. Apply Hamming window to reduce the leakage.   .   The hamming window can be coded in Matlab as   for n=1:N hamming(n)=0.54+0.46*cos((2*n-N+1)*pi/N); end;   where N is the data length in the FFT.
