lately I've been trying to connect my STM32f769I Evaluation board to Joystick. 

I've read in user manual that Joystick is connected to MFX (Multi-Functinal eXpander) over I2C1. Also I've found adress of MFX which is 1000010 in schematic. 

I have succesfully established connection over I2C1, but i don't know how to configure expander or what adress i should read/write if i want to find out which button on Joystick is pressed. 

Can someon help me with this?


Best regards,
