PINs for SPI ports
Hello, I'm curious if anyone has utilized all 5 SPI ports (at one time or another). Looking through the pin headers on the schematic, it looks as if: SPI4 is missing SCK and nSS pins; SPI3 is missing an nSS pin
Are there missing pin labels? Do they share the pins with the other SPI ports?

Here you can find all pinout options: https://developer.mbed.org/users/mbed_official/code/mbed-src/file/f26bb522183d/targets/hal/TARGET_STM/TARGET_STM32F4/TARGET_NUCLEO_F411RE/PeripheralPins.c
Yes the pinout diagrams lack labels, since it simply won't fit to put everyone on it. I don't know however if it will lack SPI labels relevant for you.
