Hello.
I am trying to migrate from stm32f407vgt6 to stm32h742vgt6, is there any difference in spi specifications?
Please give me your best regards.

    Hi,

    the H7 SPI is more complex ;

    if you use HAL calls, its about the same code (HAL doing the right things for you), 

    but if you write direct to registers - you have to make new program.

    You could glance at the chapter highlights in the RMs.

    Top of my head I'd assume the latter has more bit width options and a deeper buffer

    Thanks for the reply.
    I am thinking of migrating the code I am using in f4, but do you think I will need to modify it for h7 when I migrate it?
    Thank you in advance.
