Arduino UNO R3 + VL6180XA1 Expansion Board. How to display 7seg-led ?

I've been using Arduino UNO R3 and Nucleo VL6180XA1 Expansion Board to measure distance. However, I still can't figure out the way to display 7-seg through I2C. Can anyone explain how to transfer I2C signal to GPIO Pins of STM1600 ?
