raspberry pi 3 serial port

1. Preface I am using USB to serial port, and the chip is pl2303. It seems that Ubuntu has a USB driver of pl2303, which can be used directly. I have never tried other USB to serial ports. 2. Install minicom Enter sudo apt-Get install minicom in the terminal Download and install minicom as prompted. After downloading and installing minicom, run the command

1. Requirements:The project needs to add a USB network card to the Respberry pi, which needs some network setup for this NIC when the Respberry pi is started.2. Implementation options:(1) Add the following code to the/etc/rc.local file:if [-x/etc/mynet.conf]; Then/etc/mynet.conf fi(2) Complete the mynet.conf script and put it in the/etc/directory, the contents of mynet.conf are as follows:#！/bin/bashwhile!I

Windows is the host machine, and Linux is installed in the vmwarevm. You can also write a program in Linux to send messages to the serial port. The same principle is to use the virtual serial port software vspm to connect com3 to com4 and then capture it through the serial

The underlying application of Ti cortex m3 serial port to Ethernet routine is LWIP and the version is v1.3.2. For LWIP, a stranger can check it online. It is an open-source TCP/IP protocol written by Adam in Switzerland. Since the serial port to Ethernet routine is based on LWIP, let's see how LWIP is transplanted to T

In the python built-in class library, there is no module for serial port operations, and additional reference is required. The following two modules must be referenced in Python 2: 1. pyserial((pyserial-2.5.win32.exe) 2. pywin32 (http://sourceforge.net/projects/pywin32) Only one module needs to be referenced in Python 3. The pyserial((pyserial-py3k-2.5.win32
