smbus python

SMBus is a Python module that provides access to the System Management Bus (SMBus) protocol for communication with devices on an I2C bus. It allows you to read from and write to I2C devices using the SMBus protocol.

To use the SMBus module in Python, you need to install the `smbus` package, which can be done using pip:

pip install smbus

Once installed, you can import the module in your Python script and start using it. Here's a simple example of reading from an I2C device using SMBus:

import smbus

# Open the I2C bus
bus = smbus.SMBus(1)

# Read a byte from address 0x48
data = bus.read_byte(0x48)

# Print the received data
print("Received data:", data)

In this example, we first open the I2C bus by creating an instance of the `SMBus` class. The number `1` passed to the constructor specifies the bus number (e.g., `/dev/i2c-1` on Raspberry Pi).

Then, we use the `read_byte()` method of the `SMBus` object to read a byte from the specified I2C address (0x48 in this case). The received data is stored in the `data` variable, which we print out.

You can find more information and examples in the official documentation of the `smbus` package.
