In the picture,the pin in the blue circle is pcDuino serial data communication and its corresponding function.
TX is the data sending pin of pcDuino,namely pcDuino send data to the outside.
RX is the data receiving pin, namely pcDuino receive the data provided outside.
GND is the ground of pcDuino, to ensure the the integrity of the data transmission,
we need to connect the pcDuino GND with the corresponding module when the pcDuino is
through the serial interface to communicate with the outside data.
[/vc_column_text][vc_tour][vc_tab title=”Serial port debug” tab_id=”1393564393-1-59″][vc_column_text]Debug Port is that user via serial interface to control pcDuino through the command line mode,
completely realize all of the operation.
Due to the long time of using Windows system,
we get sued to operate computer in the friendly interface system desktop with the mouse and keyboard,
the computer is useless without the monitor, mouse and keyboard.
We could avoid carrying many peripheral devices by operating the computer with the command .
This operating computer is high efficiency and can reduce the complex of working.[/vc_column_text][/vc_tab][vc_tab title=”Part list” tab_id=”1393564393-2-10″][vc_column_text]

The following is SecureCRT interface:
The program of SecureCRT is in the attachment
Operation as follows：
1.Install the driver of FT232,the driver program is in the attachment.
Duo to the master of pcDuino is 3.3V SCM,the logic level of RS232 commonly used is 5 V and 0 V in the market.
It may lead the data abnormall with RS232 to connect pcDUino, so it is better to use the FT232.
Use the USB data line to connect the FT232 to the computer, open the device manager of the computer, show as figure
Right click “my computer” – > click “device manager”;
