Static void putpixel (u32 X, u32 y, 2010c){If (x LCD _buffer [(y)] [(x)] = C;} It is easy to find that the function of displaying a single pixel on a tft LCD is actually very simple.It seems that only LCD _buffer [(y)] [(x)] = C is required.Next, we

What is an LED? The LEDs are the initials of the light-emitting diode Lightemittingdiode. LED applications can be divided into two categories: one is led single tube applications, including backlight led, infra-red LED, and so on, the other is led display, at present, China in the production of LED basic materials and the international still have a certain gap, but in terms of LED display, China's design and production technology is basically synchronized with the international level. The

When using a computer, try not to eat anything. When you are eating things will inevitably not splash, the results of a will be caused by the keyboard and other parts of the pollution, there is likely to splash on the LCD and leave some difficult to clean stains oh. So for the cleaning of the computer and your health, or after eating to play the computer, it is good for yourself and the computer. Second, the use of time not too long and adjust the d

The LCD panel can determine to a large extent the brightness of the liquid crystal display, contrast, color, visual angle, the rapid development of LCD panels and LCD panels have a very close relationship, its output, quality and market environment, and many other factors are related to the liquid crystal display of its own quality, price and market trend, Becaus

STM32 practical application (I) -- 1602 Bluetooth Clock 1 LCD Display Test, 20171602Preface After studying for so long from 51 to ikef4, I finally got a clue. Now I have learned the basic usage of GPIO, interrupt, timer, and watchdog, so I want to see if I can do something, I just want to review my recent knowledge. Last semester, I designed a single-chip microcomputer course with a clock that can be used for Bluetooth, button calibration, and tempera

This trace is because the screen shell by external force backlog, make TrackPoint mouse or keyboard keys touch the LCD screen and caused. Configuration: Thin

LCD LCD display is the abbreviation of liquid Crystal display, LCD structure is in two parallel glass in the liquid crystal, the middle of the two pieces of glass there are many vertical and horizontal small wire, through the power or not to control the rod crystal molecules change direction, the light refraction out of the picture. Much better than CRT, but the

(2) In the interface of the LCD module, a 0.1μf filter capacitor is connected between VCC and VSS.(3) The oper

With the popularity of LCD prices, many friends began to abandon CRT and choose LCD display. Compared with traditional CRT monitors, LCD monitors offer a slightly higher price, but have many advantages: no radiation, small size, low power consumption, beautiful appearance, etc, although there are problems such as limited viewing angle, slow response speed, and we

; Register platform_driver. The kernel already has a sound LCD driver. We only need to make simple modifications based on the LCD used. The first thing to confirm is the device resource information, such as the device address and interrupt number. In the 2.6 kernel, the platform device is described by the structure platform_device, which is defined in Kernel \ include \ Linux \ platform_device.h

Symptom: A friend in the beginning of the year replaced a 15-inch LCD display, the model is AOC LM-500, has been used very normal. But just after half a year, this LCD is a failure, the specific performance: As long as the start or restart the computer, there will be an approximate "flower screen" fault phenomenon, giving people the feeling as if there is high-frequency electromagnetic interference, the scr

At the beginning, I thought it was a common practice to use gpio to drive the LCD. But it is different. This time, the FPGA board is used to drive the LCD. I checked some information. This method is similar to FSMA driving LCD.For MCU Bus, LCD has only two addresses, corresponding to rs = 0 and rs = 1 respectively.1. Write commands with RS = 02. rs = 1 Write Data

Combined with Samsung ARM9 series embedded Processor s3c2410, this paper explains how to program LCD driver modularization and how to load the driver into the system kernel statically.LCD (LCD) module to meet the increasing requirements of embedded systems, it can display Chinese characters, characters and graphics, but also has low voltage, low power consumption, small size, light weight and ultra-thin and

Because of the particularity of the notebook LCD screen, LCD panel in the factory or in the use of the process is very easy to have a bad situation, once encountered them, if the manufacturers have a better policy to protect the point, can be replaced by distributors or return to plant repair, but if within the scope of the manufacturer's provisions (generally under 3 points below), Then users can only thin
