I have a question about the amount of usable SPIs on the NUCLEO-F411 board. By default the MPU supports 5 SPI, however there is only one SPI described in the periph_conf.h. Is it just a question of adding a second (or third) one in the file, as long as GPIOs don’t overlap with other periphery, or is it more complicated than that. It is a generic question actually, in case I decide to make my own custom board but want to use some MPU that is well supported either from F1 or F4 series.
I actually don’t have a nucleo-f411 at hand, but I’m going to get 1 or 2, so I can play around with the F4s but I just want to know how complicated would be to use 3 SPIs on the board for example.
