Poorly written question. Let me elaborate.
The Nucleo-32 board I'm developing (STM32G431KB) in STM32CubeIDE shows on the CubeMX "pinout view" that there are 4 distinct pins
PB7, each with their own unique set of alternate functions. I assigned a function to each of those pins (although you don't see
PA15 populated in this image for reasons discussed below):
So after configuring my peripherals, I then went about wiring the board according to the ST User Manual. That's when I realized
PA5/PB7 are both assigned to a single pin for each pair (header
My question is thus: am I prohibited from using a pin if I am simultaneously using a completely separate pin on that same physical header pin? For example, if I'm using alternate function
SPI1 SCK on pin
PA5, is there no possible way to use pin
PB7 for anything at all? Or is there some sort of fancy GPIO muxing feature that I'm not aware of?
