For developers, just prepare the materials mentioned above and can easily get serial debugging information. The serial port debugging tools used by different upper computers are similar, basically refer to the following ways to deploy. There are many tools for serial port debugging using the Windows platform. The commonly used tools are Putty. This section uses putty as an example for deployment.<br><br>* '''Install USB driver'''Download the latest version of the driver PL2303_Prolific_DriverInstaller_v130.zip, download and extract.<div>[[File:Orange-pi-4g-iot-img26.png|800px|]]</div><br>Select application installation as an administrator<div>[[File:Orange-pi-4g-iot-img27.png|800px|]]</div><br>Waiting for installation and click.<div>[[File:Orange-pi-4g-iot-img28.png|800px|]]</div><br>* '''Download and install Putty'''Putty can be downloaded from the address below, please choose the version that suits your development environment.<br> https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.htmlDouble-click the downloaded putty.exe to open putty. The software interface is shown below.<div>[[File:Orange-pi-4g-iot-img29.png|800px|]]</div><br>* '''Acquisition of device information'''In Windows 7, we can check whether the serial port connection is normal and the serial port device No. through Device Manager. If the device is not recognized properly, please check if the driver is installed successfully. If there is a problem with the driver installation, try using the 360 Driver Master to scan the installation driver.<div>[[File:Orange-pi-4g-iot-img30.png|800px|]]</div><br>* '''Putty configuration'''Set the serial port to the corresponding port number (COM4), turn off the flow control, and set the speed to 921600.<div>[[File:Orange-pi-4g-iot-img31.png|800px|]]</div><br>* '''Start debugging serial output'''When the Orange Pi is powered on, putty will automatically print the serial port log information.<br><br>=== '''Usage based on Linux platform''' ===<br>There is a little difference using putty between Windows platform and Linux platform. The following mainly explains the differences. All operations are based on the Ubuntu 14.04 system.<br><br>* '''Install and start Putty'''<br><div style="border:1px solid #ddd;background:#f1f1f1;padding:5px;">$ sudo apt-get install putty<br>$ sudo putty</div><br>* '''Configuration Putty'''The serial port number can be viewed via ls /dev/ttyUSB* <br>The baud rate needs to be set to 921600<br>And turn off flow control<div>[[File:Orange-pi-4g-iot-img32.png|800px|]]</div><br> == '''Usage of GPIO''' ==<br>There are two methods for using GPIO:<br><br>==='''There is a general GPIO Operation Interface under Linux, “/sys/class/gpio” 。'''===<br>You could find the configuration file under the directory of “/sys/class/gpio”, the control program can be divided into four steps:<br>1、Configuring GPIO：<br><br>There is a file ‘export’ under the directory of “/sys/class/gpio”, ， you could invoke it to achieve configuration. This file have numbered the GPIO, or you could also download the schematic or get form this manual.<br><br>For example, the 37th pin on 40pins is GPIO123,you could enter：# echo 123 > /sys/class/gpio/export， and come back to the directory “/sys/class/gpio”，there will have a new directory “./gpio123”,which include the configuration files of in and out of the IO port.<br><br>Note ： export file have the permission of root write only. You have to execute as root the above command or executable file written in C.<br><br>2、Configuring the direction of GPIO (input and output):<br><br>Enter the command on the terminal：# echo "out" > /sys/class/gpio/gpio38/direction，which is set this GPIO as output.<br><br>3、Configuring the output level of GPIO：<br><br>Enter the command on the terminal：#echo 1 > /sys/class/gpio/gpio123/value，which is set this GPIO output high level， enter: echo "0" > /sys/class/gpio/gpio123/value for setting this GPIO output low level。<br><br>4、Shutting Down GPIO：<br><br>Enter the command on the terminal：#echo "38" > /sys/class/gpio/unexport，which could delete the GPIO configuration file，the directory ‘gpio38’ have been deleted.<br><br>=== '''Modify and Display the GPIO Status under ADB Mode''' ===<br>'''Get the Open/Close Status of GPIO : cat /sys/devices/virtual/misc/mtgpio/pin'''<br><br>Enter the command under ADB mode: cat /sys/devices/virtual/misc/mtgpio/pin , then it will show： pin: [mode] [pull_sel] [din] [dout] [pull en] [dir] [ies] [smt]<br><br>0:11101010<br><br>1:01101010<br><br>、、、、、、<br><br>22:1-100-10-1-1<br><br>、、、、、、、<br><br>42：00000110<br><br>'''Corresponding meaning per row：'''<br><br>IO Number：mode，pull select，input value，output value，pull enable，direction，ies '''Modify the Status of GPIO：'''<br><br> You could get the 40pin GPIO specifications from this manual or from schematic which have been uploaded to our official website: <br>http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/service-and-support/Orange-Pi-4G-IoT.html<br>For example the 37th pin on 40pins is GPIO123,<br>echo -wdout123 1 > pin -This is Set the GPIO to output high <br><br>level echo -wdout123 0> pin -This is Set the GPIO to output <br><br>high level<br><br> == '''History''' ==<br> <table style="min-width: 800px;text-align: center;" border="1" bordercolor="#d8d8d8" cellspacing="0" cellpadding="0"> <tr style="background-color: #b7b7b7;"> <td>Ver</td> <td>Data</td> <td style="font-weight: normal;">Author</td> <td>Brief</td> <td>Publish</td> <td>Me</td> </tr> <tr> <td>1.1</td> <td>2018-01-26</td> <td style="font-weight: normal;">Younix</td> <td>Create File</td> <td>2018-3-27</td> <td></td> </tr> <tr> <td>1.2</td> <td>2018-05-10</td> <td style="font-weight: normal;">Engineer Pan</td> <td>Add Android8.1</td> <td>2018-5-15</td> <td></td> </tr> <tr> <td>1.3</td> <td>2018-10-18 </td> <td style="font-weight: normal;">Engineer Pan</td> <td>Add Usage of GPIO</td> <td>2018-10-19</td> <td></td> </tr> <tr> <td>1.4</td> <td>2019-06-24</td> <td style="font-weight: normal;">Csy</td> <td>Linux source code compilation and serial port debugging </td> <td>2019-06-25</td> <td></td> </tr> <tr> <td>1.5</td> <td>2020-03-18 </td> <td style="font-weight: normal;">csy</td> <td>Linux Firmware Flashing</td> <td></td> <td></td> </tr> </table><br><br>== '''Download the Orange Pi 4G-IoT User Manual''' ==<br>For more information on using the Orange Pi 4G-IoT, please see the [https://drive.google.com/open?id=1nHRikLzsu0B85_ESL2Hcu5ns8kEBGkTd <span style="color:red;">Orange Pi 4G-IoT User Manual</span>].
