How to use with Raspbian/Ubuntu Mate/Win10 IoT Core System

Step 1, Install Raspbian official image

Download the latest image from the official download.
Install the system according to the official tutorial steps.

Step 2, modify the “config.txt”

After the programming of Step1 is completed, open the config.txt file of TF card root directory and

add the following code at the end of the file, save and eject Micro SD Card safely:

max_usb_current=1
hdmi_force_hotplug=1
config_hdmi_boost=7
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_drive=1
hdmi_cvt 800 480 60 6 0 0 0

Step 3

Insert the TF Card to Raspberry Pi, connect the Raspberry Pi and LCD by HDMI cable; connect USB cable to one of the four USB ports of Raspberry Pi, and connect the other end of the USB cable to the USB port of the LCD; then supply power to Raspberry Pi; after that if the display and touch both are OK, it means drive successfully (please use the full 2A for power supply).

How to rotate display direction

Add the statement in the “config.txt” file (the “config.txt” file is located in /boot)：
```
sudo nano /boot/config.txt
```

Add the statement in the “config.txt” file, press Ctrl+X to exit, press Y to save.
```
display_rotate=1 #0: 0; 1: 90; 2: 180;  3: 270
```
Restart the Raspberry Pi after saving.
```
sudo reboot
```

How to rotate Touch direction

After the display is rotated, the touch needs to be modified.

Install libinput

sudo apt-get install xserver-xorg-input-libinput

Create the xorg.conf. D directory in /etc/x11 / below (if the directory already exists, this will proceed directly to step 3)

sudo mkdir /etc/X11/xorg.conf.d

3. Copy the file “40-libinput.conf” to the directory you just created.
```
sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/
```

4. Edit “/etc/X11/xorg.conf.d/40-libinput.conf”

    sudo nano /etc/X11/xorg.conf.d/40-libinput.conf

Find a part of the touchscreen, add the following statement inside, press Ctrl+X to exit, press Y to save.
```
Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
```
Eg：
4. Restar your Raspberry Pi
```
sudo reboot
```

Complete the above steps for a 90 degree rotation.
Note:

0 degrees of rotation parameters: Option "CalibrationMatrix" "1 0 0 0 1 0 0 0 1"
90 degrees of rotation parameters: Option "CalibrationMatrix" "0 1 0 0-1 1 0 0 1"
180 degrees of rotation parameters: Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"
270 degrees of rotation parameters: Option "CalibrationMatrix" "0-1 1 1 0 0 0 0 1"

How to use as PC monitor

connect the computer HDMI output signal to the LCD HDMI interface by using the HDMI cable
Connect the LCD's USB Touch interface (Either of the two MicroUSB) to the USB port of the device
If there are several monitors, please unplug other monitor connectors first, and use LCD as the only monitor for testing.

FAQ=

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TF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TF卡烧写镜像不成功或TF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：
