PySerial with Python: Detailed Code Sample

To demonstrate the power and simplicity of PySerial, let’s look at a detailed code sample that showcases how to establish a serial connection, send data, and read incoming data.

Installation

First, you need to install PySerial. You can do this using pip:

Code Sample

Here’s a complete example of how to use PySerial in Python:

Explanation

• Serial Configuration: The serial.Serial object is configured with the appropriate port and baud rate. Adjust the port parameter to match your device's serial port.
• Sending Data: The send_data function converts the string to bytes and sends it over the serial port.
• Reading Data: The read_data function checks if there is any incoming data and reads it if available.
