10. Driver Library and Communication Configuration

This example demonstrates the process of installing and configuring the serial port and I2C driver libraries. The factory image already has these configured, so you can skip this step.

1. Python I2C driver

Open the terminal and enter the following command to install

xxxxxxxxxx
sudo pip3 install smbus

Python imports the smbus object

xxxxxxxxxx
import smbus
bus = smbus.SMBus(1)

I2C read and write examples

xxxxxxxxxx
# Write data and write data blocks
bus.write_byte_data(addr, reg, data)
bus.write_i2c_block_data(addr, reg, data_array)

# Read data
recv = bus.read_word_data(addr, reg)

2. Python serial port driver

Open the terminal and enter the following command to install

xxxxxxxxxx
sudo pip3 install pyserial

Python imports the serial object

xxxxxxxxxx
import serial
ser = serial.Serial('/dev/ttyUSB0', 115200)

Serial Port Read and Write Example

xxxxxxxxxx
# Write a block of data
ser.write(data_array)

# Read data
recv = ser.read()
