Will continuous gpio write have any bad effects?

Postby joe_fang_iD » Tue Nov 05, 2024 6:56 pm

I'm writing a code that is setting the gpio output continuously (not oscillating) to the same level.
for example, the following code is run once every 2-10ms.

digitalWrite(PIN_5, 0);

Will there be some sort of damage, maybe wear and tear to some fets/bjt in the hardware or something? Or a timing delay?
