ADC0809是廣泛使用的模/數(shù)轉(zhuǎn)換器,在可不采用外部總線結(jié)構(gòu)的單片機系統(tǒng)中(如 由AT89C51組成的系統(tǒng))。ASC0809的數(shù)據(jù)線直接與單片結(jié)構(gòu)的I/0 口相連,并由單片機的I/O 口直接對ADC0809進行控制。

程序是根據(jù)vidcat改的,只能抓PPM的圖. makefile的內(nèi)容如下,請注意打小寫: cc=gcc #cflags=-i/firendly-arm/kernel/include -i/usr/local/arm/2.95.3/arm-linux/include -wall -dhave_libjpeg #-dvideo_dev=\"/dev/v4l/video0\" -dversion=\"0.7.2\" cflags=-wall -dvideo_dev=\"/dev/video0\" -dversion=\"0.7.2\" camsnap: camsnap.c 用法如下: camsnap -v -s 420x420 -o my.ppm 這兒請注意:s 的大小必需是8能整除的倍數(shù). 這個程序我是在rh9下作的,需要交叉編譯的朋友就把注釋去掉,再給下面的注釋就可以了.

I want to provide an example file system driver for Windows NT/2000/XP. For some time I have worked on an implementation of RomFs. RomFs is a small filesystem originally implemented in Linux, because of its simple disk layout its a good choice for an example driver. The current status is a working read-only driver that supports caching of file data, the create functionallity still needs some work but I m releasing it due to the high public demand.

In this article, I will explain how to create UDP packets and then send them to a remote server through the Internet using WinPCap for Windows. The code has been tested to work with Windows XP SP2 and Vista SP1 on Linksys routers, and on Toshiba modems connected directly to the Internet. Please note that the code here is very minimalistic, and can be greatly expanded depending on your needs. The reason I use WinPCap in this article is that it solves the issue of Winsock for Windows (XP SP2 and above) not allowing raw UDP packets to be sent (in Linux, you can just use regular sockets). With WinPcap, it is possible to specify your own source IP and source hardware addresses in packets.

mkdosfs - Make DOS file system utilty. I wrote this, partially to complement the dosfsck utility written by Werner Almesberger (who graciously gave me some pointers when I asked for some advice about writing this code), and also to avoid me having to boot DOS just to create data partitions (I use Linux to back up DOS :-) ).

模擬Linux文件系統(tǒng) 在任一OS下,建立一個大文件,把它假象成一張盤,在其中實現(xiàn)一個簡單的模擬Linux文件系統(tǒng)。 1. 在現(xiàn)有機器硬盤上開辟100M的硬盤空間,作為設(shè)定的硬盤空間。 2. 編寫一管理程序simdisk對此空間進行管理,以模擬Linux文件系統(tǒng),要求: (1) 盤塊大小1k (2) 空閑盤塊的管理:Linux位圖法 (3) 結(jié)構(gòu):超級塊, i結(jié)點區(qū), 根目錄區(qū)
