import time
import board
import busio
import adafruit_lsm9ds1

# I2C connection:
i2c = busio.I2C(board.SCL, board.SDA)
sensor = adafruit_lsm9ds1.LSM9DS1_I2C(i2c)

while True:
	x, y, z = sensor.acceleration
	print('x:{}, y:{}, z:{}'.format(x,y,z))

Details

I2C is a communication protocol using 2 wires. Read more here and here.

• SAM32 already has pull-up resistors on the SCL and SDA lines, so you don't need to add those

• default pin names are:

  board.SDA
  board.SCL
