1. After installing the PLC programming software Step 7 microwin on Windows 7, can the communication between the programming software and the PLC fail? Cause: Step 7 microwin does not support win7 very well Solution: Install the Virtual Machine in win7, the XP system in the virtual machine, and step 7 microwin under XP 2. One-way data transmission: the PLC sends correct data to PC serial 1 (baud rate 9600), but two-way data transmission: PC serial 1 sends data to PLC first. After the

, we're going to introduce one of the most important concepts: pixel density, which is the PPI (pixels per inch). This indicator is a bridge connecting the digital world to the physical world.Pixels per inch, exactly, is the number of pixels in the length of the line. 1 inches is a fixed length, equal to 2.54 centimeters, about the length of the knuckles at the end of the index finger. The higher the pixel density, the finer the representation of the

of the screen * pixel points per column; The resolution of the phone is determined at the factory and cannot be changed. Image resolution: The number of pixels in an image per inch. Image resolution is a unit, called pixels per unit (px/in); Screen Size: Only the physical length of the screen diagonal, immutable, in inches (in); Screen pixel density: (PPI) refers to the number of pixels per inch on the diagonal of the screen; at normal di

Pixel Pixel Basics:Pixels are the basis of a page layout. A pixel is the smallest area in which a computer can display a particular color. When the device is the same size but the pixels become denser, the screen can display a more detailed transition and the site looks more crisp.Px:pixel, pixels, the smallest unit displayed on the screen for web design, intuitive and convenient;Pt:point, is a standard length unit, 1pt=1/72 inches, for the printing industry, very simple to use;EM: That is,%, in

For different Apple devices, see IOS: Model parameters, SDK, Xcode versions for each of the parameters.model ChangesCoordinates: Indicates the physical size of the screen, the coordinates become larger, indicating that the machine screen size has become larger;Pixels: Indicates the size of the screen picture, with a correspondence between coordinates, such as 1:1 or 1:2, etc.;PPI: A scale value representing the physical size of the screen to the size

multiples of twice and 3 times times the graph.Screen pixel density refers to the number of pixels per inch, DPI, is the abbreviation of "Dot per inch", the PPI is "Pixel per inch" abbreviation, pixels per inch, dpi=ppi for the design of the display.The calculation method is the length and width of the pixels of the square of the sum of the root, divided by the diagonal length (in inches), such as the ipho

ObjectiveiOS and Android use the same set of iOS interactive design This practice is noncommittal, after all, a lot of people do so, for this we are in development to be able to convert the size of the appropriate resolution, we can directly compare the resolution of the two sides directly conversion, for example: iOS: (640*1136px) X 75% = iOS: (480*852px) ≈android (WVGA hdpi):(480*800px), know this can be converted according to the corresponding proportionScreen Basics iphone Interface Size:

should I emphasize that it is a concept on a software system? Because when you buy a cell phone, you often hear another parameter called PPI, which is the pixel density on the phone screen, but this is the concept of physics, it is an objective existence will not change. DPI is a user-specified value after the software references a physical pixel density, which ensures that the physical pixel density within a range uses the same value on the software

resolution densities are 163 PPI, 132 PPI, and 326ppi, and the 3GS and ipad controls respond to pixels that are close to the 44PX standard, while iPhone4 need to be enlarged several times. 2. Lack of visibility and consistency Take the ipad pages app, for example, for example, there are 2 objects in the manuscript, and you want to make it the same size, there are two ways: you can use the edge guides to m

dot-matrix graphic as a combination of many different colors of square color blocks,And every square color of a different color we call a pixel (Pixel).2. Resolution (resolution) refers to the number of dots or pixels that a digital image contains in the unit length.For example: An image resolution of 100 dots per inch is called 1OODPI(Dots per Inch).3. In some digital image processing software, each point is called a pixel (Pixel),So the resolution unit is also called

But to put it another way, the go language supports multiple assignments, and the variables are is initialized by default. At the same time, the go language also supports pointers, but its pointers are much more secure. Golang [CPP] view plain copy var k int FMT.

Before iOS6, screen fit general use AutoSize to set the dimension relationship of the view to the parent view Defect: (Insufficient autosizing layout) 1. Cannot set the relationship between views and views 2. You cannot set the size to zoom in, the maximum value is reduced, the minimum value After iOS6, use automatic layout. AutoLayout IOS8 size classes (more abstract, square) In addition, some of the major device parameters a

The canvas elements of HTML5 and the programming interfaces that accompany them are widely used in the canvas API. Simply put, a canvas element can create a rectangular area in a Web page that can be a canvas, which can draw various shapes. Do not underestimate this canvas, it can achieve unlimited possibilities. Let's start with the simplest part and get to know the powerful features of canvas.1. Add a canvas element to the page:By default, canvas creates a rectangular area that is 300 pixels w
