實驗基本條件：
Orange_Pi_PC *1（含5V3A電源，32G高速卡）

7英寸TFT液晶顯示屏

燒錄工具：SDFormatter ，Win32DiskImager
PS：順便吐槽一下，在某寶上購買以上産品不帶任何配件，即所有電源，信号線都要獨立購買。切記！！！
Step1：
從Armbian官網上下載下傳Armbian Xenial版本的鏡像，然後解壓得到Armbian_5.38_Orangepipc_Ubuntu_xenial_default_3.4.113_desktop.img檔案
然後将TF卡裝到SD卡套上，插入筆記本的SD卡槽，啟動SDFormatter，并将TF卡格式化。
格式化完成後，關閉SDFormatter，并打開Win32DiskImager，選擇剛才解壓的鏡像，選擇正确的TF卡盤符，點選write即可燒錄。
燒錄完成後，安全彈出SD卡，并将TF卡插到Orange_Pi_PC的TF卡槽。
正确連接配接液晶顯示屏驅動闆，驅動闆與Pi_PC之間用HDMI線連接配接，Pi_PC接上區域網路，區域網路啟用DHCP。
确認信号線連接配接好之後，就可以上電了，液晶顯示屏的驅動闆也是要獨立供電的。
Step2:
上電後，網絡接口會閃爍，如果網絡接口沒反應的或，應該檢查系統是不是沒刷好，還是TF卡沒裝對。
如果一切正常的話，大概2分鐘左右，網絡接口的燈就常亮了。這時就可以通過SSH遠端連接配接了，如果不知道IP的話，可以上路由器檢視線上客戶，或者用arp -a查找。

#這時，系統會檢測到顯示屏，并提示修改顯示參數
Your display settings are currently 720p (1280x720). To change this use the
h3disp utility. Do you want to change display settings now? [nY] y
Usage: h3disp [-h/-H] -m [video mode] [-d] [-c [0-2]]
############################################################################
This is a tool to set the display resolution of your Orange
Pi by patching script.bin.
In case you use an HDMI-to-DVI converter please use the -d switch.
The resolution can be set using the -m switch. The following resolutions
are currently supported:
480i use "-m 480i" or "-m 0"
576i use "-m 576i" or "-m 1"
480p use "-m 480p" or "-m 2"
576p use "-m 576p" or "-m 3"
720p50 use "-m 720p50" or "-m 4"
720p60 use "-m 720p60" or "-m 5"

推薦：h3disp -m 1024x768
修改後會提示：Now trying to patch script.bin with your settings. Successfully finished. Please reboot for changes to take effect 必須重新開機才能使配置生效。
如果現在不修改的話也可以，稍後可以通過armbian-config工具來配置。
修改IP位址，使Pi_PC可以上網更新，并運作apt update,apt upgrade來更新。
更新完之後，運作 sudo timedatectl set-timezone Asia/Shanghai 更新時區。
運作 sudo armbian-config 進入如下界面
選擇System
選擇Display，然後選擇合适的分辨率輸出，，選擇輸出類型
系統會提示重新開機。
正常情況下，顯示屏會有畫面看的了。
如果顯示屏一直是白屏，請檢查：
1、顯示屏是否正常工作，試試連接配接其他HDMI輸出裝置。
2、HDMI連接配接線是否松動。
3、分辨率是否正确，desktop_service是否關閉。
4、重新安裝lightdm （sudo apt install lightdm），并修改預設自登陸賬戶(sudo vi /etc/default/nodm)
