Why is the pin on a Nucleo 144 not outputting a high enough voltage, despite the output being set to HIGH?
I am trying to control a stepper motor, using a A4988 driver along with a Nucleo 144 board with an STM32F767ZI on it.
The A4988 driver expects a single rise in voltage to HIGH in order to step the motor.
Having made some voltage readings using a…
