Kevin O'Connor 116b304541 avr: Switch to input state prior to enabling pullup in gpio_in_reset()
If switching a pin from output low to input with pullup, there is an
intermediate state of either driven high or high impedance without a
pullup.  Similarly, when switching from output high to input without a
pullup, there is an intermediate state of either driven low or high
impedence with a pullup.  In both cases it is preferable for the
latter transition.

Also, calculate the final setting prior to making any changes to
reduce the time in that intermediate state.

Welcome to the Klipper project!

Klipper

https://www.klipper3d.org/

The Klipper firmware controls 3d-Printers. It combines the power of a general purpose computer with one or more micro-controllers. See the features document for more information on why you should use the Klipper software.

Start by installing Klipper software.

Klipper software is Free Software. See the license or read the documentation. We depend on the generous support from our sponsors.
