Which GPIO I can use in my project?
-
I need 5 digital channels for my project.
I tried use GPIO03, GPIO01, GPIO16, GPIO17 but unsuccessful
or apprication crashed at random time or no signal reading -
Gpio 26,Gpio 22, Gpio 21, Gpio16, Gpio17 Gpio 5 Gpio 2 could all be used, What are you trying to control with those pins? Could it be that you are drawing too much power? I tried to drive some heavy duty servo's before and the M5Stack would crash.
