STM32L4R9I Discovery Board and MFX Documentation

[ffabi]

Hello I’m using a STM32L4R9I Discovery board at the moment and want to have some documentation besides the demo code about the MFX µC on the board wich is in charge of e.g. the joystick and the power measurement. In the User manual for the discovery board I found the schematic, but I would need something a documentation about the I2C interface in order to use the board.

best regards

Proper documentation for the MFX​ has been requested before. Really needs a data sheet and reference manual. I can infer a lot of stuff from the BSP sources, but that shouldn't be necessary.
