![]() ![]() If you installed the full Anaconda distribution of Python, PySerial comes pre-installed. To use the PySerial package with Python, PySerial first needs to be installed. USB and is built upon and extends the original serial communication interface. Serial communication protocol predates the USB specification used by computers and other pieces of hardware like mice, keyboards, and webcams. Serial communication is one of the oldest computer communication protocols. ![]() PySerial provides an interface to communicate over the serial communication protocol. PySerial is a useful package for problem solvers because it allows us to exchange data between computers and pieces of external hardware such as voltmeters, oscilloscopes, strain gauges, flow meters, actuators, and lights. A computer running Python with the PySerial package installed can communicate with external hardware. PySerial is a Python package that facilitates serial communication. The next piece of code is an infinite loop, which does a few things.Problem Solving with Python Book Construction.A port also cannot be accessed if it has not been opened. It is imperative that the open() function is called, because it allows our program to âclaimâ the port and prevent any other processes from accessing it. In our simple program, we first open the serial port defined previously. in_waiting â This variable holds the number of bytes in the buffer.write(data) â This will write the data passed to the function to the serial port.read(size) â This will read n number of bytes from the serial port.readline () â This will read a string from the serial port.close() â This will close the serial port. ![]() open() â This will open the serial port.Using the serial port is very easy and only requires a handful of functions, including. ![]()
