Install pySerialTransfer in Python Easily

pySerialTransfer is a Python library for fast serial communication. It simplifies data transfer between devices. This guide covers installation and basic usage.

Prerequisites

Before installing pySerialTransfer, ensure you have Python 3.6 or later. You also need pip installed. Check your Python version:

import sys
print(sys.version)

3.9.7 (default, Sep 16 2021, 16:59:28) 
[GCC 10.3.0]

Install pySerialTransfer

Install pySerialTransfer using pip. Run this command in your terminal:

pip install pySerialTransfer

For virtual environments, activate yours first. If you need help with virtual environments, see our Install PyGObject for GTK+ in Python guide.

Verify Installation

Check if pySerialTransfer installed correctly:

import pySerialTransfer
print(pySerialTransfer.__version__)

2.0.0

Basic Usage Example

Here's a simple example to send data between devices:

from pySerialTransfer import pySerialTransfer as txfer

# Create connection
link = txfer.SerialTransfer('COM3')  # Replace with your port

# Open connection
link.open()
print('Connection opened')

# Send data
send_size = 0
send_size = link.tx_obj([1, 2.5, 'a'], send_size)
link.send(send_size)

# Close connection
link.close()
print('Connection closed')

The tx_obj method prepares data for transfer. The send method transmits it.

Receiving Data

To receive data on the other device:

from pySerialTransfer import pySerialTransfer as txfer

link = txfer.SerialTransfer('COM4')  # Receiver port
link.open()

while True:
    if link.available():
        rec_size = 0
        data = link.rx_obj(obj_type=list, 
                          obj_byte_size=10, 
                          list_format='i f c',
                          start_pos=rec_size)
        print('Received:', data)
        
    elif link.status < 0:
        print('ERROR:', link.status)
        
link.close()

The rx_obj method unpacks received data. Specify the expected format.

Troubleshooting

If you encounter errors:

1. Check port permissions

2. Verify baud rates match

3. Ensure proper cable connections

For complex installations like Install PyTables with HDF5 Support in Python, additional steps may be needed.
