Interrupts are an important part of embedded systems, which leads to a lot of compiler developers providing an extension-letting standard C support break. The representative fact is that a new keyword __interrupt has been produced. The following code uses the __interrupt keyword to define an interrupt service subroutine (ISR), please comment on this code.

Double area = PI * radius * RADIUS;printf ("ar
ISFP is a command package for service interruption. There are three scenarios for creating ISR:1. Eight commands in An ISFP package can satisfy ISR requirements.2. ISR can occupy multiple consecutive ISFP (provided that the following interruptions are not used)3. ISR is located outside of istIn the preceding figure, B
1. System interruption and clock cycle
1.1 system interruption
Interrupt is a hardware mechanism that notifies the cpu Of an asynchronous event. Once the interrupt is identified by the system, the CPU stores partial (or all) context values, that is, the values of some (or all) registers, and jumps to a special subroutine, it is called the interrupt service subroutine (ISR ). Interrupt Service subprograms are used to process events. After processing is
Interrupt service routines (ISR)
ISR: interrupt service routine)
The so-called interruption refers to an external event (such as a level change, the occurrence of a pulse edge, or the overflow of the timer count) when the CPU is processing something) the request is processed by the CPU quickly, so the CPU temporarily suspends the current job and forwards it to the processing of the event. After the inci

After consulting the relevant documents, finally realized, now take it out and share with you. Perhaps people will ask: "This is inconsistent with the title?" "Don't worry, before I write, I think about some of the problems I had when I was using Form authentication, and some of the techniques I used i

The first three articles in the CSDN forum after the announcement, the effect is like "immortal fart--really different from every (counter) ring." In order to thank the broad masses of netizens enthusiasm and support, this is not, after a while of brewing, cultivation, deliberately prepared the fourth ring.
We have previously described the use of form authentication to achieve a single sign-on, as netizens said, can only be used under the same domain name. For a single sign-on
Abstract access authentication is a method that the Web server can use to negotiate authentication information with the Web browser. It applies a hash function to the password before it is issued, which is more secure than the HTTP Basic authentication sent in clear text. Technically, Digest authentication is a MD5 cryptographic hash function application that uses random numbers to prevent password parsing. It uses the HTTP protocol.First, the basic process of summary
