Is it a GPIO pin on the board or a USB terminal? I think it's the GPIO pin that doesn't cost money. > Since RPi does not have a serial port, it goes without saying that serial communication will be performed from other interfaces. But that's the only difference, so it's very easy to describe.Īccess to that port can be described in the same way as access to a file object, so it's easy to think about.
I saw / dev / ttyUSB0.Įven if you write using PySerial, the windows com port or Linux device name remains in the python script. On Linux machines, including the Raspberry Pi, you can see the device name under / dev by ls. The COM port number to be connected is the USB-serial port number when the COM port is displayed in Device Manager before and after the USB-serial is connected. () Installation method, transmission example, reception example (Https:///site/hananekosugan/manual-tips/python/pyserial) There are examples of sending and receiving
() Example of sending with Python (windows) For me, I decided to check out the library for Python. What I can do with Python is what I want to do with Python. It is displayed with the device name such as. On Linux (including Raspberry Pi), IO for USB-serial conversion is

Recently, even PCs have no RS232C port, so a USB serial conversion cable and a USB serial conversion driver are required. Libraries only (static + dynamic) is open to the public. It is stated that Boost C ++ libraries can be built on Raspberry Pi. # ** Highly portable serial port library (C ++) Boost **īoost, which provides a common OS-independent library, provides a library for serial ports.Ĭommentary article serial communication]() When controlling hardware, the library used tends to differ depending on the type of CPU and OS. Please note that it is a memo by a person who rarely confirms the contents on the actual machine. It's a memo that I'm looking into for studying because it's becoming necessary.
