在树莓派Raspbian &Ubuntu Mate系统中使用
步骤1,安装Raspbian或UbuntuMate官方镜像
- 从官方下载最新Raspbian镜像 https://www.raspberrypi.org/downloads/ 从官方下载最新Ubuntu Mate镜像 https://ubuntu-mate.org/download/
- 使用SDFormatter格式化Micro SD卡，
- 使用Win32DiskImager把官方镜像烧录到Micro SD卡。
步骤2,与树莓派连接
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
- 方法一：在线安装(树莓派需连接互联网)
- 登陆树莓派终端(SSH远程登录用户名:pi 密码:raspberry) SSH无法连接？
- 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
资源下载
- 文档
- 驱动下载
- 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。
