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 7寸1024*600高清应配置为： hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt 1024 600 60 6 0 0 0
