Python Pyserial Readline Example
Syntax
- Install Pyserial. Before installing Pyserial, we need to get pip: sudo apt install python-pip. Now we can go on to install Pyserial: python -m pip install pyserial Test installation and read console. To read our console, we need to connect the Raspberry Pi USB port to Arduino one. For testing purposes, I'll show you results from my weather system.
- Welcome to pySerial’s documentation¶. This module encapsulates the access for the serial port. It provides backends for Python running on Windows, OSX, Linux, BSD (possibly any POSIX compliant system) and IronPython. The module named “serial” automatically selects the appropriate backend.
