Introduction to DMA and Direct Memory Access for STM32, dmastm32 The first time I came into contact with DMA, I learned the arm9-bare-board program at school. I thought it was almost two years later. Now let's take a look at the dma of the STM32 platform. With the support of the standard peripheral library, the DMA programming of the STM32 is very simple, but it is not only learning, let's take a moment to learn about the concepts and principles of DM

The direct network is divided into two types, point-to-point link and multiple access link,For a network number of direct connected network, the above two kinds of link to calculate. Examples are as follows:1. How many directly-connected networks is there on the route from host A to host B in the following figure?We will mark the point-to-point link between AB and multiple Access link:Among them, the Red sq

This article describes how to directly back up data files in MySQL and how to execute SQL statements in actual operations, the following is a detailed description of the main content of the article. I hope you will gain some benefits after browsing it. Compared with the previous methods, backing up data files is the most direct, fast, and convenient. The disadvantage is that Incremental backup is basically not supported. To ensure data consistency, r

This article mainly introduces thinkphp range query, statistical query, and SQL direct query. it analyzes the common query techniques of ThinkPHP in details in the form of examples, which is very useful, for more information about the thinkphp interval query, statistical query, and SQL direct query, see the examples in this article. Share it with you for your reference. The specific method is as follows: I

This article is mainly for the introduction of the PHP sorting algorithm series of direct selection of relevant data, with a certain reference value, interested in small partners can refer to Direct Select sort The basic idea of direct selection sorting (straight select sorting) is to select the minimum value from r[0]~r[n-1], to switch to r[0], to select the sm

) Using the SQLite engine directly, the performance of a large amount of data is good (only one SQL statement is required). Consumes less memory More Light weight Android and WP also support Disadvantages of using SQLite directly Complex object relationships are maintained on their own No object change Tracking Not really object-oriented programming needs to be supplemented Performance-related assessmentOverall, performance is not significantly diff

Direct selection sorting is the simplest and most intuitive sorting algorithm, which belongs to the selection Sort.Direct algorithm Sorting ideas: The first trip, the program will record positioning on the first data, take the first data in turn and the following data to compare, if the first data large, exchange, and so On. After the first comparison, the smallest data in this set of data is selected and ranked First. On the second pass,

Apache prohibits direct IP access At the end of the httpd.conf file, add the following code The code is as follows Copy Code Namevirtualhost 1.1.1.1# # Here assume that the IP to be banned is 1.1.1.1 ServerName 1.1.1.1Order Allow,denyDeny from allThe # # implementation rejects any access requests directly through 1.1.1.1 this IP, at which point you will be prompted to deny access if you use 1.1.1.1 accessDocumentRoot "/va

The basic idea of a direct insert sort (straight insertion sorting) is to look at the N-sorted elements as an ordered table and an unordered table, beginning with an ordered table containing only one element, and an unordered table containing n-1 elements. Each time the first element is taken out of an unordered table, it is inserted into the appropriate position in the ordered table, making it a new ordered table, repeating n-1 times to complete the

Share to everyone for your reference. Specific as follows: Problem: The template contains: /public need direct output, but. /public will be replaced directly with the current public template directory, with the final

A friend of mine a few days ago asked me how to debug the direct connection mode of a common Broadband Router. Turn me dizzy. It is not difficult to adjust. But does not know how to explain it .. I happened to help people debug a wide R1000 + router yesterday. next I will take it as an example to describe how to set up the direct connection mode of a vro: first, for a Broadband Router, its connection method

This can only be used as an example for your initial understanding of MDA. Functions: Pass the string data to utxh0 through the dma0 channel, and then Display. After data transmission, dma0 is interrupted, beep sound, and LED light. Basic DMA knowledge Common Data Input/Output Methods in computer systems include query methods (including unconditional and conditional transmission methods) and interrupt methods, which are suitable for data exchange between CPU and low-speed and medium-speed peri

Bubble Method 1st: Compare 0 and 1, 1 and 2, 2 and 3 in sequence... n-2 and n-1 index at the elements, found that the front is greater than the back, exchange them, so a trip down, the largest element ranked to the end. 2nd: continue to follow the 1st practices. The second largest element comes to the end. ...... In this way, N pieces of data are sorted after N-1 comparison and exchange. If a trip is not exchanged, it indicates that the sorting has been completed and the sorting can be completed

I don't need to analyze it professionally. I use dummies to answer questions. This is a simulated question. Use this question as an example. URL type: Of course, it is Class B.

Speed of direct CILS vs interfaces vs delegates vs events als Consider the following code: interface IProcessor { void Process(); } class Processor: IProcessor { public void Process() { } } If I write something like: Processor P = new processor ();P. Process (); The compiler will emit code that tightly binds to processor. Process (). In other words, the only function that cocould be called is that function. That means that the JIT can easily inlin

The user-mode direct read/write port in the NT environment should have been from to 96What we talked about when the architecture just came out was a last resort. Because a friend asked me a few days ago about iopm in TSS.Table problems, while most of the articles available in this regard on the Internet are just a general discussion. There are no principles for empty implementation methods, and there is no way to directly reference them. These article
