supports ARM7, arm11, Cortex-M3 core, support ads, IAR, Keil development environment. In addition to all the functions of the previous v7.0 version, v8.0 has been improved in both hardware and software: (1) v8.0's SWD hardware interface supports the 1.2-V target board, v7.0 only supports target boards of 3.3v. (2) v8.0 uses two-color LEDs to indicate more statuses. v7.0 only has one LED indicator. (3) v8.0 enhances the JTAG driver capability and improves the compatibility of the target board. (

What is robots.txt? Robots.txt is a plain text file that is the first file to be viewed when crawling a Web site, typically located at the root of the site. The robots.txt file defines the restrictions that the crawler has when crawling the site, which parts of the crawler can crawl and which cannot be crawled (anti-gentleman)More robots.txt protocol Information reference: www.robotstxt.orgBefore crawling a Web site, check the robots.txt file to minimize the possibility of spiders being bannedTh

, the computer (PC) at that time is generally connected to the port, so the connection computer is defined using the same port. And the computer to today, do not say notebook computers, now desktop computers have a few of the same port, and replaced by more and more USB interface. Then can you let JTAG support USB protocol, with USB interface to debug arm? This is going to be about Jlink and Ulink.Note: For the JTAG principle, please refer to the article "Jtag Debugging Principle".Jlink Emulator

judgment, but I prefer the second method for a large number of hierarchies. The first method is easier if you have smaller queries but need to add and update data frequently. In addition, if the database is supported, you can also write Rebuild_tree () and space-making operations into the database-side trigger functions, which are automatically executed at the time of insertion and update, so that you can get better operational efficiencies, and your SQL statements for adding new nodes will bec
