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？)
- 从官方下载最新Raspbian / Ubuntu Mate镜像
- 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(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
