		+	=='''Instructions for use LcPiTester_V3S soft'''==
		+	The following is the test method using Putty general software. For customers who want to speed up the test,they can use the V3S special test software developed by LC Technology,as shown in the figure below:<br>
		+	[[File:V3S 24.png]]<br>
		+
		+	Instructions for use:<br>
		+	1.Connect the peripherals that need to be tested (such as LCD),connect the serial ports (GND,U0T,U0R),and supply power to the board<br>
		+	2.Select the correct port number,baud rate 115200,click "连接",and a lot of debugging information will be printed out in the window at this time. After the system startup is complete,click "断开",and then click "连接",and the following information will appear Log in to the Linux system successfully,and the function test can be performed<br>
		+	[[File:V3S 25.png]]<br>
		+
		+	''Remarks: The software only supports ports within COM9. If the port number recognized by the computer exceeds COM9,please modify the port number in the Windows Device Manager.''<br>
		+
		+	Take the test LCD as an example:<br>
		+	1.Check "随机色点",click "执行",if the test is successful,the LCD will be covered with random color dots<br>
		+	[[File:V3S 26.png]]<br>
		+
		+	[[File:V3S 27.jpg]]<br>
		+
		+	2.At this time,the software will ask whether the test is successful. If you click "是",the random color point will display green[[File:V3S 28.png]]otherwise it will display red. The test method for the rest of the functions is similar to this<br>
		+
		+
		+
		+
		+	=='''Source code compilation'''==
		+	1.Install the virtual machine VMware Workstation (in the sn.txt in the activation code installation package)<br>
		+	[[File:V3S 29.png]]<br>
		+
		+
		+	2.Unzip the CherryPi_V3S-Build-2020-07-14.7z file<br>
		+
		+
		+	3.Open the installed VMware Workstation software, click "Open Virtual Machine", and locate the newly decompressed the CherryPi_V3S.vmx file in the folder CherryPi_V3S is enough.<br>
		+	[[File:F1C200S-38.png]]<br>
		+
		+	[[File:V3S 31.png]]<br>
		+
		+
		+	4.Then click the green play icon on the left or in the menu bar "Start this virtual machine"<br>
		+	[[File:V3S 32.png]]<br>
		+
		+	''Remarks:''
		+	The processor parameters here may need to be changed according to the computer parameters you actually use, such as a 4-thread CPU，Then the parameter behind the processor is changed to 4.<br>
		+	The interface after entering is as follows<br>
		+	[[File:V3S 33.png]]<br>
		+
		+
