Add GPIO21

Hello,
You can add pins38 (GPIO20) and pin40 (GPIO21) in the future.
My electronics uses these pins.
We have now changed to setup_config.html and configure the pins before the printer starts.
If I update, I need to restore the changes.

Thank you.

Re: Add GPIO21

As you know some of the GPIOs reserved for SPI like interfaces. To use them, it requires to blacklist and disable some functionality which is difficult and hard to explain to users.

The upgrades would not change GPIO pins, only when submit data on setup page it will get overwritten,.

hello ionel.ciobanuc ,

can you please share how to edit setup_config.html in order to manually change pins used.

I already soldered my servo to GPIO to pin 21 before I realized it wasn't an option in the dropdown menu..

thanks!
