When we do presentations outside or when we want to see pcduino desktop but without HDMI monitor ,how we can do? Currently we have seen are using VNC connection, but in the middle there must be a router, but when no routers or other network switching equipment ,how can we do? It will only connect pcduino net mouth directly with computer network port .we’ll introduce some method about direct connection as below.
Wiring diagram: P3 of pcduino is the system debug serial port. There are 3 pins in total, pin1 is the RX connected to usb TXO, the middle one GND connected to TXO, the rest one TX is connected to usb RXI.[/vc_column_text][/vc_tab][vc_tab title=” Command and Demonstration diagram” tab_id=”1393898379617-2-6″][vc_column_text]The hardware is ready, you can start to do the experiment.Plug the usb serial module into the computer and install the driver ,and then open any a serial port tool,select this serial port tool, the baud rate is set to 115200 ,no parity parity, 1 stop bit. Some tools used to set ascii display .Plug pcduino in the Ethernet cable( note with your computer to the same network segment ),and supply power to pcduino.At this time ,from the serial port tool ,you can see a lot pcduino startup information .When “root@ubuntu:~# ” occurs on the sreen , that is the system has been lauched, this time you can begin to operate.
At this time if you enter “ifconfig-a” can not see the IPV4 , so we can not use VNC connection , but we can specify the ip address to pcduino through command. The methord is as follow:
First, we enter “ifconfig eth0 192.168.15.2 boardcast 192.168.15.254 netmask 255.255.255.0” in the input window and input “enter”.Inside address and gateway can easily set up , but with the network port of your computer as a gateway .
Then click send. This time can output information on pcduino .
Seems to be a little wrong, but it doesn’t matter.In order to confirm the success of the next ip address is set successfully, enter “ifconfig-a” command to check the next .
This time we can use this ip address to connect pcduino through VNC on the computer. ( If you do not move over a period of time , IP address pcduino will be lost, need to re- set , and sometimes have to restart pcduino, the solution is to fix IP address pcduino ,the method for your reference : http://cnlearn.linksprite.com/?p=3639 )[/vc_column_text][/vc_tab][/vc_tour][/vc_column][/vc_row]
