How to use gravity sensor SEN0409 with unihiker

Hello everybody, 

i wrote a script for my Raspberry 5 using pyQt5 and LIS Series Python Library for get acceleration from two DFRobot_LIS2DW12 devices [0x18 et 0x19].

 I get the accelerations values, display to the widget and send it via websocket to another computer.

 Now i want to do the same thing with an uniker board. Somebody have a small exemple for me? When i try, i have errors when i set the I2c channel.
