Turn: http://blog.csdn.net/kickxxx/article/details/7236040 Startup Mode MX51 supports four startup modes. These modes are determined by the solder joints on the IC Package (boot_mode 0/1). After reset, the two solder joints are sampled, then save their status to the SRC Boot Mode register (sbmr) Register. The solder joints correspond to logic 0. For logic 1, nvcc_per3 is recommended for Freescale. The four boot modes are internal, reserved, internal boot with fuses, and serial boot through USB/U

Scrapy mainly includes the following components :engine : Used to process the entire system of data flow processing, triggering transactions.Scheduler : Used to accept requests sent by the engine, pressed into the queue, and returned when the engine requests againDownloader : Used to download Web content and return the contents of the Web page to the spider.spider : Spider is the main work, use it to make a specific domain name or Web page parsing rulesProject Pipeline : Responsible for handling

is obviously wasteful;② For example, we want the control to display a default image (such as a gray avatar) when the network is downloading the picture, or to display a circular progress bar when the picture is downloaded, then the code above is not available;③ again, we want to download a variety of images, for different site sources have different ways to download ....These special needs tell us that the above code is completely out of the way. So for the completeness and scalability of the c

Web crawler, is the process of data crawling on the web, use it to crawl specific pages of HTML data. Although we use some libraries to develop a crawler program, the use of frameworks can greatly improve efficiency and shorten development time. Scrapy is written in Python, lightweight, simple and lightweight, and easy to use. I. OverviewThe following figure shows the general architecture of the Scrapy, which contains its main components and the data processing flow of the system (as shown in

If you do not want to see this prompt, add a parameter after the Mount command, specifying that the device be mounted read-only.The next steps:4. Go to working directory, e.g./tmp/5.

spider class. I originally planned to write a batch download spider, but later I found that the implementation can be modified based on the original downloader class, so I directly changed the downloader class. This is the current example. BaseThe idea is that the scheduler generator will wait for the next parsing result after all URLs are generated, and then generate and return the parsing result. AddCall
