ILI9341液晶显示

ILI9341液晶显⽰17.1液晶显⽰原理TFT-LCD(Thin Film Transistor Liquid Crystal Display)即薄膜晶体管液晶显⽰器，是微电⼦技术与液晶显⽰器技术巧妙结合的的⼀种技术。

CRT显⽰器的⼯作原理是通电后灯丝发热，阴极被激发后发射出电⼦流，电⼦流受到⾼电压的⾦属层的加速，经过透镜聚焦形成极细的电⼦束打在荧光屏上，使荧光粉发光显⽰图像。

LCD显⽰器需要来⾃背后的光源，当光束通过这层液晶时，液晶会呈不规则扭转形状（形状由TFT上的信号与电压改变实现），所以液晶更像是⼀个个闸门，选择光线穿透与否，这样就可以在屏幕上看到深浅不⼀，错落有致的图像。

⽬前主流的LCD显⽰器都是TFT-LCD，是由原有液晶技术发展⽽来。

TFT液晶为每个像素都设有⼀个半导体开关，以此做到完全的单独控制⼀个像素点，液晶材料被夹在TFT阵列和彩⾊滤光⽚之间，通过改变刺激液晶的电压值就可以控制最后出现的光线强度和⾊彩，如图7-1所⽰。

图7-1 液晶显⽰屏结构图Kingst-32F1开发板配套的TFT-LCD是3.2⼨⼤⼩，分辨率为240*320，即⼀共有240×320=76800个像素点，每个像素都设有⼀个半导体开关，像素之间是相对独⽴的，这么多像素如何控制呢？联想⼀下51单⽚机驱动LED点阵时，为了减少IO⼝的使⽤，采⽤三⼋译码器驱动点阵模块。

同理，TFT-LCD也可以⽤专门的驱动器来驱动，教材所⽤的TFT-LCD采⽤ILI9341驱动芯⽚。

该控制芯⽚是封装在TFT-LCD内部，只留有外部引脚接⼝。

对于⽤户来说，只要掌握如何向ILI9341控制器发送指令和读写数据，并不需要再设计额外的驱动电路，该液晶的具体参数如表7-1所⽰。

7.1.1ILI9341硬件接⼝和像素格式ILI9341驱动芯⽚主要由接⼝电路、显存(GRAM)、LCD驱动电路、背光控制、电源等部分组成，主要结构如图7-2所⽰。

tft背景色清屏函数 -回复

tft背景色清屏函数-回复TFT背景色清屏函数TFT（Thin-Film Transistor）液晶显示屏是一种高清、高分辨率的显示技术，广泛应用于许多电子设备中，如手机、智能手表、电视等。

在TFT显示屏上，可以通过编写代码控制屏幕的各种属性，包括背景色、文字颜色等。

本文将重点探讨如何编写一个TFT背景色清屏函数，让您能够更好地控制TFT显示屏的背景色。

首先，我们需要了解一下液晶显示屏的基本原理。

TFT显示屏是由很多微小的液晶单元组成的，每个液晶单元可以控制通过它的光的强度。

通过控制每个液晶单元的光强，整个屏幕就可以显示出所需的图像或文字。

当我们需要改变TFT显示屏的背景色时，实际上是改变了每个液晶单元透过光的颜色。

现在，让我们开始编写TFT背景色清屏函数的步骤。

第一步：确定使用的TFT库TFT库是一个用于控制TFT显示屏的软件模块，可以通过它来操作液晶单元。

在编写TFT背景色清屏函数之前，您需要确定使用哪个TFT库。

这里以Adafruit GFX库为例。

该库是一个功能强大且易于使用的TFT控制库，支持多种TFT显示屏。

第二步：包含必要的头文件和定义全局变量在编写清屏函数的代码之前，需要包含所需的头文件，并定义一些全局变量。

这些变量可以用来存储TFT屏幕的尺寸、背景色等信息。

以下是一个示例：c++#include <Adafruit_GFX.h>#include <Adafruit_ILI9341.h>#include <SPI.h>TFT屏幕的尺寸#define TFT_WIDTH 320#define TFT_HEIGHT 240背景色#define BACKGROUND_COLOR ILI9341_BLACKAdafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_RST, TFT_CLK, TFT_RST, TFT_MISO);在这个例子中，我们使用了Adafruit_GFX和Adafruit_ILI9341库，定义了TFT屏幕的尺寸为320x240，背景色为黑色（ILI9341_BLACK）。

基于STM32的万年历设计

基于STM32的万年历设计基于STM32的万年历设计班级：姓名：学号：成绩：电子通信工程系题目:基于STM32的万年历设计前言：随着科技的快速发展，时间的流逝,至从观太阳、摆钟到现在电子钟，人类不断研究，不断创新纪录。

美国DALLAS公司推出的具有涓细电流充电能的低功耗实时时钟电路DS12C887。

它可以对年、月、日、周日、时、分、秒进行计时，还具有闰年补偿等多种功能，而且DS12C887的使用寿命长，误差小。

对于数字电子万年历采用直观的数字显示，可以同时显示年、月、日、周日、时、分、秒和温度等信息，还具有时间校准等功能。

该电路采用AT89S52单片机作为核心，采用数字式温度传感器DS18B20提取外界温度，功耗小，能在3V的低压工作，电压可选用3~5V电压供电。

进入新世纪LCD显示屏的技术和产业都取得了长足的发展，作为重要的现代信息发布媒体之一，LCD显示屏在证券交易、金融、交通、体育、广告等领域被广泛的应用。

伴随社会信息化进程的推进，LCD显示屏技术也在不断的推陈出新，应用领域愈加广阔。

基于STM32的LCD显示可以更好的满足各种需求，也更便于操作和实现。

现基于STM32在液晶显示屏幕上显示文本及图形。

目前，显示技术和显示工业的发展迅速。

显示技术是传递视觉的信息技术。

液晶显示器件LCD是当今最有发展前途的一种平板显示器件，它具有很多独到的优异特性。

它具有显示信息多、易于多彩化、体积小、重量轻、功耗低、寿命长、价格低、无辐射、无污染、接口控制方便等优点。

截至目前，我国在液晶显示取得较大进步，我国LCD产业已经走过了近30年的历程.经历几次大的投资浪潮之后,我国内地已经成为世界最大的TN-LCD(扭曲液晶显示器)生产基地和主要的STN-LCD(超扭曲液晶显示器)生产基地,并且从2003年开始,涉足TFT-LCD(薄膜晶体管液晶显示器)领域.本课题设计采用STM32F103VE开发板，实现在LCD显示屏上显示由按键可操控的万年历功能。

2.8吋彩色液晶屏汇编语言实验程序

上一次发表的是用C语言编写的2.8 吋彩色液晶屏实验程序，这一次是汇编语言编写的2.8 吋彩色液晶屏实验程序，两个程序的运行结果是完全一样的，只是编程用的编程语言不同而已。

对于初学C51单片机的朋友们学习不同语言编程能有所帮助，本程序是经过本人上机测试完全通过Keil 4 验证的，可以放心的使用。

本程序驱动ILI9341 或RM68090 芯片驱动的2.8 吋彩色液晶屏。

显示点阵数：240RGB(W)×320(H)。

芯片为宏晶科技公司的STC12C5A60S2或STC12LE5A60S2 芯片。

注：RGB 为565 格式的16bit。

arduinotft代码

以下是一个基本的Arduino TFT库的使用示例代码。

这个代码将显示一些文本和一些图片。

这个代码是使用Arduino IDE编写的，因此你可以直接把它上传到你的Arduino板上。

首先，确保你已经安装了Adafruit TFT库。

你可以在你的Arduino IDE中，点击“工具”-> “管理库…”-> 在搜索框中输入“Adafruit TFT”-> 点击“安装”。

```cpp#include <Wire.h>#include <Adafruit_GFX.h>#include <Adafruit_ILI9341.h>#include <SPI.h>#define TFT_CS 10#define TFT_RST 9#define TFT_DC 8Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_RST);void setup() {Serial.begin(115200);tft.begin();tft.setRotation(3); // This sets the screen orientation. Adafruit ILI9341 driver supports 0,1,2,3 so you can choose depending on your screen size and resolution}void loop() {// Draw some texttft.clearBuffer(); // clear display buffertft.setTextSize(2); // set text sizetft.setTextColor(WHITE); // set text colortft.setCursor(20, 50); // set text positiontft.println("Hello, world!"); // print text to display// Draw an imageif (!tft.loadImage("test.bmp")) { // if image is not loaded successfullySerial.println("Image not found!"); // print error message to serial monitorwhile (1); // halt program execution}tft.drawImage(0, 0, 320, 240, "test.bmp"); // draw image on the display at position 0,0 with dimensions 320x240tft.display(); // update display buffer to screen}```这个示例代码将通过SPI接口连接一个ILI9341 TFT屏幕，并显示“Hello, world!”文本和一些图片。

ILI9341讲解

IC(ILI9341)讲解姚青华2011年5月15日讲解内容：•简单介绍•（一）ILI9341特点•（二）ILI9341框图•（三）芯片管脚★•（四）芯片尺寸•（五）块功能简述•（六）功能详述★•（七）命令寄存器★•（八）RAM•（九）同步信号TE •（十）省电模式•（十一）上电/断电顺序•（十二）功率等级定义•（十三）Gamma曲线设置•（十四）复位•（十五）电源配置电路•（十六）烧录•（十七）电气特性ILI9341是一颗单片系统级，262,144色，分辨率为240RGB X 320的TFT液晶驱动芯片。

芯片内部包括一个720个通道源驱动，320个通道门驱动器，一个172，800字节图形显示数据的GRAM 240 RGB X 320D点，并带有供电模拟电路。

解释：262,144色=R5 R4 R3 R2 R1 R0 ,G5 G4 G3 G2 G1 G0 ,B5 B4 B3 B2 B1 B0=2^6 X 2^6 X 2^6。

720个通道源驱动= 240RGB = 240 X 3 =720320个通道门，不言而喻172,800字节GRAM=(240x320x18)/8。

成本构成：通道源数+通道门数+GRAM大小+通信接口+模拟电路拓展：大尺寸屏的驱动通常是多个单独的通道源驱动和门驱动芯片驱动。

（一）ILI9341特点1、显示分辨率：[240xRGB](H)x320(V)。

2、输出：720源输出，320门输出，常见的电极输出VCOM。

3、GRAM：172,800字节。

4、接口：8/9/16/18位，8080模式MCU接口；6/16/18位RGB接口；3/4线串口。

5、显示模式：全彩模式（空闲模式关闭），26万色（颜色深度模式可由软件设定）；减色模式（空闲模式），8色阶。

6、省电模式：睡眠模式。

7、片上功能：VCOM生成和调整；时序发生器；振荡器；直流/直流转换器；线翻转/帧翻转；独立的RGB伽马校正预设伽马曲线。
