Then, from another terminal on a remote PC connected to the same network, use the command described in How to perform ssh connection. If the network connection is through Ethernet then "InterfaceNetwork" = "Eth0", else if the network connection is using Wifi then "InterfaceNetwork" = "WLAN0"Įth0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx: FB using a console (see chapter Remote terminal via Serial link (UART/USB).if it exists, using the board user interface (Terminal window or specific application). To do so, first get the IP address of the board: The board can also be accessed via the network through Ethernet connection, using ssh. You can for example reboot the board and see the boot sequence. The setup is correct when you can send Linux ® commands through the terminal emulator and get feedback. More information on the board serial port can generally be found in the hardware user manual of the board.Open a terminal emulator application on your PC and configure with the serial setup menu the USB port to be used and the baud rate of the serial link (in general 115200 baud).Īny of the Windows ® terminal emulator applications can be used. On the terminal, the prompt is changed information on Minicom can be found at the following link. See below example for a standard UART (ttyS0) or STLink interface (ttyACM0): See How to use TTY with User Terminal article to find the appropriate tty instance to be used. Hardware flow control is generally set to off (default value is on) and a baud rate of 115200 is usual. The UART configuration that is set with the below command has to match the one from your board: to be checked within board user manual. If a message indicating Minicom does not exist, then install it:.You need first to check that Minicom is installed on your PC. Pictures describing board connections can be found in Category:STM32_MPU_boards 1.1 On Linux ® PC 1 Remote terminal via serial link (UART/USB)ġ Remote terminal via serial link ( UART/USB) įirst of all, you need to connect your host PC to the board via UART.ĭepending on the board, some additional materials may be needed to physically interconnect the board to the console serial port (extension board or adapter to interconnect the UART from the board to the USB PC input).The main widget is passed as the parent, so the object deletion happens automatically according to the parent and child mechanism in Qt:Ĭonst SettingsDialog ::Settings p = m_settings - >settings() The serial port is instantiated in the MainWindow constructor. SettingsDialog ( terminal/settingsdialog.cpp) - is a dialog for configuring the serial port, as well as for displaying the available serial ports and information about them.The program was written to work with the Kantronics range of TNCs but should work with any TNC that is connected to a serial port on your computer. The widget is derived from the QPlainTextEdit class. TNC - The Packet Terminal Driver program is a general purpose communications package for communicating with a packet TNC attached to your IBM-PC/clone. Console ( terminal/console.cpp) - is the central widget of the main window, displaying the transmitted or received data.MainWindow ( terminal/mainwindow.cpp) - is the main application window that contains all the working logic for the serial port programming, including configuration, I/O processing and so forth, while inheriting the QMainWindow.The Blocking Receiver example illustrates the synchronous approach. In this example, the asynchronous approach is demonstrated. QSerialPort::waitForReadyRead()) to suspend the calling thread until the operation has completed. In non-GUI and multithreaded applications, the waitFor.() functions can be called (i.e. When the data is sent to the serial port, QSerialPort emits bytesWritten(). For example, QSerialPort::write() returns immediately. QSerialPort emits a signal when the operation is finished. Operations are scheduled and performed when the control returns to Qt's event loop. The asynchronous (non-blocking) approach.QSerialPort supports two general programming approaches: Also, the class QSerialPortInfo is invoked to display information about the serial ports available in the system. This example shows the main features of the QSerialPort class, like configuration, I/O implementation and so forth. Terminal shows how to create a terminal for a simple serial interface by using Qt Serial Port.
