ATT, attribute Protocol, protocol for discovering, reading, and writing to-end devices (for BLE devices) 1 Introduction
ATT allows a device to provide a set of attributes with associated values as a serverLet the device as a client to discover, read, write these attributes, and the server can actively notify the client
The ATT defines two roles: server and Client

3. Description
[Att $ = val]. If the end character of the attribute value represented by att is the character specified by val, this style is used for this element.
Assembly languages depend on the architecture. In Linux, the compiled assembly by GCC is an ATT syntax assembly by default. This article mainly introduces ATT Assembly: operand length, immediate number representation method, register reference, operand sequence, symbol constant, memory Reference.
1. The length of the operand
The length of the operand is expressed by the symbol after the instruction in B
immediate suffix are labeled "H" and "B" respectively, while at/T, hexadecimal immediately preceded by "0x", table 2.2 gives several corresponding examples.Table 2.2 The difference between Intel and the-t prefix

A new att assembly problem (coming soon)-General Linux technology-Linux programming and kernel information. For more information, see the following. This is what I wrote. I want to use the bubble algorithm to arrange a group of data and then output the data. but I always feel a bit problematic. I hope the experts can help me ......

1 each element has one or more attributes that are used to give additional information about the element or its contents, such as: In an IMG element, SRC is the attribute of the element, and the address that marks the image2 main DOM methods for operating characteristicsGetAttribute methodSetAttribute methodRemoveAttribute method3 jquery uses the attr () method to get and set element properties, attr is an abbreviation for attribute (attribute)4 Expression of attr ()attr (incoming property name)
There are three ways in which jquery offers usData ()Att ()Prop ()To set and get the properties of an object. But the design of these three methods does not repeat the useless design, then the three of their distinction is where it.Demo attr () Method: is the integration of the getattribute () and setattribute () methods in JSUsage is the most routine.$ (' div '). attr ({age:30,address: "Tianjin"});var = $ (' div '). attr ("Age");$ (' div ').

Flex 4 brings us a brand new namespace. Understanding these namespaces must be a good thing. Flex 4 has three important namespaces:
Xmlns: FX = "http://ns.adobe.com/mxml/2009 ″
Xmlns: MX = "Library: // ns.adobe.com/flex/halo"
Xmlns: S = "Library: // ns.adobe.com/flex/spark"
