Different controllers can support display of passive Array Display (STN) and Active Array Display (TFT), including monochrome and color, one-way refresh mode and two-way ref

Implementation principle of LCD driver in Embedded System From: http://www.laogu.com/wz_18338.htm Source: Today's electronics Author: Yang xianqiang, Sichuan University, Tian Yuanfu Details: This article describes how to implement Modular programming of the LCD driver and how to load the driver into the system kernel statically Based on Samsung's arm9-series embedded processor S3C2410.

The 12864 dot matrix LCD module (LCM) is a 128*64-row array consisting of 128*64 LCD display points. Each display point corresponds to a binary number. 1 indicates bright, and 0 indicates extinct. The ram that stores the dot matrix information is called the display data storage. To display a graphic or Chinese character, you need to write the corresponding dot matrix information to the corresponding storage

Next let's take a look at the LCD. c file in 2440test. 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

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

; 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

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

Transferred from: http://blog.sina.com.cn/s/blog_664c545f0100v9zl.htmlReprint: http://www.mculee.cn/post/48.html"1" LCD Driver basicsThe Linux-2.6.32.2 core already supports the s3c2440 LCD controller driver, but here we introduce some basic knowledge about the 2440 LCD controller and the driver-related LCD.Note: Here we only discuss TFT

When you buy an LCD monitor, you should know that debugging them is completely different from the previous debugging of CRT monitors. If you do not know this matter, then hurry to follow me, step by step, the LCD to the best state it! Although these techniques are mainly for LCD, but some of them will also help the CRT, so still using CRT monitor friends, do not

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

It has always been known that EFM32 LCD Controller supports simple animation effects without MCU involvement. However, there is no time to summarize this function. Take the time to sum up, so on the basis of tg stk, a detailed description, so that you do not have to forget for a long time. The final effect is as follows: Note: Gecko is not displayed completely because I disconnected PE13. Used to test EM4 GPIO wake-up. The
