在树莓派Raspbian &Ubuntu Mate系统中使用

步骤1,安装Raspbian或UbuntuMate官方镜像 (Q:不会安装？)

  1. 从官方下载最新Raspbian / Ubuntu Mate镜像
  2. 使用SDFormatter格式化Micro SD卡，
  3. 使用Win32DiskImager把官方镜像烧录到Micro SD卡。

步骤2,与树莓派连接

左|无框





如图将液晶屏母座靠右对齐树莓派排针插入   
插入MicroSD卡，连接网线，接好电源     





步骤3,安装LCD驱动(树莓派需连接互联网)

(1)登陆树莓派终端(SSH远程登录用户名:pi 密码:raspberry) (Q:SSH无法连接？)
(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):
sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
sudo ./MHS35-show
(3)执行完上述命令后，系统自动重启后就能正常显示和触摸了
注意事项：安装此驱动后HDMI输出将会禁用，如需切换回HDMI显示，执行:
sudo ./LCD-hdmi

  • 驱动下载
  1. 本地下载:LCD-show.tar.gz
  • 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TF卡中。然后把卡插入树莓派就可以使用了。
