Where to find source code of the CHIP I/O Expander MFX_V3 ( STM32L152)

[HNguy.4]

I am using the Evaluation board with STM32H743XI . Please let me know where to find source code of the IO expander Board MX_V3 on this EVAL board or a link to download it.

Thank in advanced

I second this. I search through the whole website but no detailed information on this chip.

ST, could you please provide us with source code and/or documentation of the MFX used on the STM32F469-EVAL board, presumably the same as on the H7 board ?

Thanks.
