Hi Daniel, I hope you're doing well!

 

I'm sorry to say, but there's no way to set the pin to LOW without any delay by using software, as, even if you, for example, save the pin state and recover it after a reset, it would still take some time to change to LOW. You could also try setting the pin from the bootloader, but it wouldn't be without delay either.

 

One way to set a DIO pin to LOW without delay could be by setting a pull-down resistor connected to it.

 

Best regards,

Sebastian
