The serial port receives sends the data to have two kinds of ways, one is the interrupt mode, the other is the DMA way, here mainly in the interruption way, looks at uses the serial port to send, receives the data the entire process. Here is an

Press power key to slow down the screen speed problem Causes and solutions: The delay in the resume function of each driver, and the delay of the thread inside the charging driver need to be re-viewed, compared with the original code, except for

The pre-processing process scans the source code and performs initial conversion to generate new source code for the compiler. It can be seen that the preprocessing process processes the source code prior to the compiler. In C language, there is no

1. Introduction C ++ language was originally created as "a better C ", however, this does not mean that the compilation and connection methods used by global variables and functions similar to C in C ++ are the same as those in C. As a language to

First, I will reference this article "ARM Linux kernel startup requirements". ARM Linux kernel boot requirements was written by Russell king, the maintainer of the ARM Linux kernel. CPU register settings R0 = 0. R1 = machine type number.

To http://blog.csdn.net/rnamatrix/article/details/5765462 Today, when using the numeric_limits class template functions Max and min in limits, an error occurs during compilation: [c-sharp] view plaincopyprint? error C2589: '(' : illegal token

Resolution # pragma command Among all the pre-processing commands, the # pragma command may be the most complex. It is used to set the compiler status or to instruct the compiler to complete some specific actions. # The Pragma command provides a

The trial version does not have the source code. A message "register" is displayed before each running. You can use it if there is no time limit. Disadvantage: the properties of the drag-and-drop control cannot be set, so you have to set it in the

Deep Exploration of the meaning of extern "C" in C ++ 1. Introduction C ++ was originally created as "a better C", but this does not mean that C ++ has global variables similar to C. And functions are compiled and linked in the same way as C. As a

Analyzing the startup code has always been a small ideal for me. I couldn't find a method for a long time. Later I read some basic books and finally got started with some videos, therefore, I also want to analyze some experiences and see if my

This article contains "Linux Device Drivers", that is, the fourth chapter of LDD3: One of the Reading Notes of Debugging Techniques, but we are not limited to this content. I saw the English version of LDD3 on the Internet:

The member variable in the ev_loop struct in libev, libevev_loop 1. ev_loop is the struct used by libev to describe the event loop. The definition in libev is relatively difficult. Here we extract it and make comments to facilitate learning. Libev

Record some points in the learning process:   When you are doing a project, you can use the class in the project to create variables in the solution menu. For projects in different directories, put the same type together, including the header
