Cromfs is a compressed read-only filesystem for Linux. Cromfs is best at archiving gigabytes of big files that have a lot of redundancy. It aims primarily at achieving a strong compression, even at the cost of memory and CPU time resources. It uses the LZMA compression algorithm from 7-zip and Block merging.

A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, Block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.

java 线程 静态锁，对象锁， synchronized 是锁方法还是锁对象？还是锁类？如何实现？？ 部分代码如下， public static Object lock=new Object() //静态锁，锁类，不是锁对象了！！所以两个线程同时 运行两个 TestThread 的execute（ ），也可以同步！！！ public void execute(){ // synchronized(lock){ for(int i=0 i<20 i++){ try { Thread.sleep(30) } catch (InterruptedException e) { // TODO Auto-generated catch Block e.printStackTrace() } System.out.println(Thread.currentThread().getName()+Thread.currentThread ().getName()+" "+i) } } }

Among the many features built into Microchip’sEnhanced FLASH Microcontroller devices is the capability of the program memory to self-program. This very useful feature has been deliberately included to give the user the ability to perform bootloading operations.Devices like the PIC18F452 are designed with a designated“boot Block”, a small section of protectable program memory allocated specifically for bootload firmware.

本帖最后由 黄瓜 于 2014-3-2 21:39 编辑 在2012年，帖子“圆点博士微型四轴飞行器开工拉...有钱出钱，没钱出力” http://www.amobbs.com/thread-5504090-1-1.html得到坛友的大力支持。经过2013年的全年发展，资料已经相当成熟。楼主把全部资料整理到了一起，方便大家下载。 首先给大家介绍下这些资料的内容：(全部是源代码，豪无保留)： 1,小四轴飞行器源码：包括陀螺仪芯片驱动代码，数字滤波，四元数姿态解算和电机控制代码，此外，还包括蓝牙无线传输代码，NRF24L01+无线传输代码，小四轴无线更新固件代码。 2,小四轴手持遥控器源码。包括USB转COM口代码，蓝牙编程代码，摇杆控制代码，和液晶屏显示代码。通过该代码，用户可以学习USB编程，蓝牙编程，摇杠编程，液晶屏显示编程能知识。 3,基于windows/Linux下的上位机代码，能过获取小四轴姿态，并对小四轴进行飞行控制。该代码使用垮平台算法QT编写。 4,基于Android的手机遥控器代码，可以实现对小四轴的飞行控制 5,对国外著名开源crazyflies开源算法的姿态部分的移植(已修改成大家熟知的MDK环境)，带FreeRTOS操作系统。
