常见问答=

问题:使用光盘/网盘提供的树莓派镜像,无法正常使用LCD,怎么处理?

答复:
  • 确定硬件连接无误且接触良好
  • 确定Micro SD卡烧写正常,系统启动是否正常。
  • 树莓派正常启动时PWR灯常亮,ACT灯闪烁。
  • 如果发现两灯都常亮则可能是Micro SD卡烧写镜像不成功或Micro SD卡与树莓派接触不良。
  • 推荐使用5V 2A电源适配器对树莓派进行供电。 如使用电脑USB接口供电,可能由于供电不足导致树莓派无法正常启动。


问题:使用树莓派官方提供的镜像, LCD无显示是什么原因?

答复:
  • LCD需要安装驱动才能正确显示,具体请参考”如何安装LCD驱动”相关说明文档,
  • 建议先使用我们提供的镜像,测试通过后,再自行安装驱动程序。


问题:装好驱动后如想切换回传统显示器进行显示,如何操作?

答复:
  • 请参考”如何安装LCD驱动”相关说明文档,使用以下命令切换:
    sudo ./LCD-hdmi
    


问题:使用7寸HDMI屏时显示正常但无触摸功能,如何处理?

答复:
  • 检查触摸排线接插处是否运输松动
  • 检查USB一端是否连接树莓派4个USB口中任意一个,另一端连接到液晶屏的USB Touch接口.
  • 可先将USB触摸连接到电脑USB口,观察是否能正常被电脑识别并正常触摸,以此可以判断触摸功能好坏,


问题:问题:更新升级镜像之后无法使用?

答复:
  • 更新需按照以下方式进行,否则可能导致镜像无法运行:
    sudo apt-mark hold raspberrypi-bootloader
    sudo apt-get update
    sudo apt-get upgrade
    


问题:5寸和7寸屏连接到电脑HDMI,无法正常显示,怎么解决?

答复:
  • 确定电脑的HDMI接口可以正常输出
  • 电脑只连接LCD作为显示设备,不连接其它的显示器(拔掉其他显示器)。
  • 先接USB供电线再接HDMI线。
  • 尝试重启电脑。
  • 必须使用windows操作系统。


问题:在树莓派3代上,怎么打开蓝牙功能?

答复:
  • 方法1:升级到树莓派官方最新镜像(2016-05-27-jessie之后版本已经默认打开蓝牙功能);
  • 方法2:手动打开蓝牙功能
    sudo apt-get install pi-bluetooth
    sudo apt-get install bluetooth bluez blueman 
    systemctl status bluetooth
    sudo systemctl start bluetooth
    sudo reboot
    


问题:使用5寸7寸HDMI屏时无法全屏或显示残缺,如何处理?

答复:
  • 检查HDMI是否已经插好并且输出正常
  • 打开SD卡根目录下config.txt文件,检查HDMI配置是否正确
  • 5寸和7寸800*480应配置为如下参数:
    hdmi_group=2
    hdmi_mode=1
    hdmi_mode=87
    hdmi_cvt 800 480 60 6 0 0 0
