lcd marquee

A recent project because the layout textview content is too long. The first thought is the marquee effect, so the TextView once again their own definition, although the effect of the happy lantern is achieved. Just cause there is a problem is edittext input problem, when the first click on the EditText can pop up the soft keyboard, just the soft keyboard off, again click on the TextView will not be able to play a soft keyboard, baffled its solution. S

There are many ways to implement a marquee, the simplest of which is to use an HTML code to implement, we insert the " Parameters Usage Introduction Behavior=scroll, Slide, alternate Happy way: Cycle around, only once to stop, back and forth movement Direction=left,right Racing direction: Left to right, right to left loop=100 Happy times: loop 100 times, if not write default t

This time I'll talk about how the control flow from the MCU to the LCD is how our bitmap data is displayed on the LCD. Before we learned that the LCD display is implemented by dynamic scanning, each time a full line is displayed, each line in a frame is scanned once, so that there is a circuit to control the output voltage on the row and column, this circuit is t

I have a piece of stm32f429 discovery Board, for some reason need to use 8080 interface lcd, and the block Development Board comes with the LCD interface using LTDC drive, so on the right atom here bought a 4.3 inch capacitive touch screen, driver IC for the NT35510.In order to quickly build a software engineering, I use the STM32CUBEMX tool to generate code templates, and write the LCD.C and nt35510.c two

If you use a Linux OS, use an LCD or CRT monitor-Linux general technology-Linux technology and application information. For more information, see the following. One person has two monitors, one is a Samsung LCD and the other is a Samsung CRT. It is better to use a Windows LCD to see the effect, it won't be uncomfortable if you have watched your eyes for a long ti

, right, up, and down.Behavior: The way to set up scrolling is mainly in three ways: behavior= "Scroll" means scrolling from one end to the other, behavior= "slide": a quick slide from one end to the other, and no repetition; behavior= " Alternate "means to scroll back and forth between the ends.Height: Used to set the height of the scrolling marquee.Width: Sets the length of the scrolling marquee.Hspace and Vspace: Sets the width of the left and right borders and the top and bottom borders of t

Liquid Crystal has 1 or 2 ends as the power supply, 15, 16 for the back light source; to prevent the Direct Addition of 5 V voltage burned back light, 15 pin a 10 euro resistance for throttling. The LCD 3 end is the LCD contrast adjusting end, and uses a 10 k euro potentiometer to adjust the LCD contrast, The four ends of the liquid crystal are the data writing/r

One, the first way:　　Implemented by the TextView control's own properties (but the disadvantage is that when multiple TextView want to achieve this effect, only the first one has an effect)The implementation method adds the following four properties:Android:singleline= "true"Android:ellipsize= "Marquee"Android:focusable= "true"Android:focusableintouchmode= "true"LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_widt

Method One: (can only achieve a single textview of the marquee effect)In TextView add the following controls android:singleline= "True" can only be a single line, the excess text appears as "..." android:ellipsize= "marquee" ellipsis no, but no marquee effect Android: Focusable= "true" android:focusableintouchmode= "true" method two: (can achieve multi-line TextV

DemandThe project needs to use a marquee to display only one message, the appropriate length does not scroll, too long the cycle of scrolling.Although I did not write, but looked at the code, is in a uiview inside put two Uilabel,At the end of the previous one, the other shows. However, click Processing is indeed a UIView click event.However, see, such as Subway, bus inside the marquee is divided into a lot

In the CRT era, screen flicker is a common fault, usually caused by insufficient refresh frequency of the display card. Many users do not know what the refresh rate is, plus the system default is 60 Hertz, many users often use a lot of years low refresh rate to understand the CRT screen can not flicker. To the liquid crystal display era, environmental protection without radiation, and no flicker and other features become the biggest selling point of liquid crystal display. However, some users
