I'm using a nucleo f722ze which has an onboard stm32f722ze.
GPIO_D pin 9 remains above 1.5 V even when it's set as off("reset state"). Every other pin I've used and tested doesn't resemble this behavior. They go straight down to 0V.
Image of me toggling this pin:
What I've done:
I've literally generated a blank project and this pin still stays at 1.5V, I've tried initializing the pin and forcing it to the reset state, but still it stays at 1.5V.
I'm not sure if I'm overlooking something, what could be causing this?
Thanks in advance for any help!
