MPI5008-11.jpg

产品介绍

  • 5inch标准显示器,硬件分辨率800×480
  • 带电阻触摸屏,支持触摸控制
  • 支持背光单独控制,可关闭背光节省功耗
  • 支持标准HDMI接口输入,兼容并可直接插入树莓派(3代2代1代)
  • 可作为通用HDMI显示器使用,如接电脑HDMI作为副显示器(分辨率输出要能调整为800X480)
  • 如仅用作显示则无需占用IO资源(树莓派使用触摸功能时需占用IO资源)
  • 本产品通过CE、RoHS认证

产品参数

  • 尺寸: 5.0(inch)
  • SKU: MPI5008
  • 分辨率: 800×480(dots)
  • 触摸: 4线电阻触摸
  • 外形尺寸: 121.11*77.93(mm)
  • 产品重量: 175(g)

硬件说明

524x524像素
① USB 供电接口:USB供电输入(5V),如图④母座已连接树莓派取电,则此USB可不接
② HDMI 接口:用于连接主板和 LCD 显示屏进行HDMI传输
③ 背光开关:控制背光打开和关闭,可节省功耗
④ 电源和触摸接口:从树莓派取电给液晶屏,同时将触摸信号通过GPIO回传至树莓派
⑤ 扩展接口:将图④母座占用的GPIO口PIN对PIN引出,方便扩展使用


在树莓派Raspbian/Ubuntu Mate/Win10 IoT Core系统中使用

  • 步骤1,安装官方镜像
  1. 从官方下载最新镜像
  2. 按官方教程步骤安装好系统
  • 步骤2,安装LCD驱动

方法一:在线安装(树莓派需连接互联网)
1)用Putty连接登陆树莓派系统到用户命令行(初始用户名:pi 密码:raspberry)
2)执行以下命令(复制后在Putty窗口中单击鼠标右键即可粘贴):

git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
sudo ./LCD5-show

方法二:离线安装
1)从光盘中拷贝“LCD-show.tar.gz”驱动到树莓派 系统卡根目录下;
(推荐步骤1烧录完成后将驱动直接拷贝到Micro SD卡,或使用SFTP等办法远程拷贝)
2)执行以下操作命令解压安装驱动:

cd /boot
sudo tar zxvf LCD-show.tar.gz
cd LCD-show/
sudo ./LCD5-show


  • 步骤3,

将Micro SD卡插入树莓派,将HDMI线连接树莓派和LCD,将USB线连接树莓派的4个USB口任意一个,USB线另一端连接到LCD的USB口,然后给树莓派上电,如显示和触摸均正常则驱动成功(请使用足2A电源供电)。

如何作为电脑显示器使用

使用HDMI连接线将电脑HDMI输出信号连接至LCD的HDMI接口;
将MicroUSB连接线一端连接LCD的USB Touch接口(两个MicroUSB任意一个均可),另一端连接至电脑的USB端口。
如有多个显示器,请先拔掉其他显示器接口,将本LCD作为唯一显示器进行测试。
作为电脑显示器用,触摸功能将不可用。


如何旋转显示和触摸

文档/视频

驱动下载

镜像下载

如果你觉得前面步骤的修改配置、安装驱动都比较困难或者仍然显示异常,

请先使用我们预装好驱动的镜像,下载后解压并把镜像写入到Micro SD卡中。然后把卡插入树莓派就可以使用了。

常用软件


Question: Using the Raspberry Pi image provided by the CD/net disk, cannot use the LCD normally.

Answer:

  • Confirm that the hardware connection is correct and the contact is good.
  • Determine whether TF card is normal and whether the system is started normally.
  • The PWR lamp is always bright when the Raspberry Pi is started, and the ACT light is flashing.If you find both lights on,

it may be the TF card does not successfully burn the image file,or that the TF card is not in contact with the Raspberry Pi.

  • Recommend using 5V 2A power adapter to power the Raspberry Pi.
