Pull up/down resistors are typically "required" by the circuit. In your case where you're using a device that tends to be used as a switch. Leaving the circuit floating can cause unexpected behavior. So, is it "required" ? No. Is it desired? Yes. On Fri, May 13, 2016 at 9:14 AM, Chad Baker <[email protected]> wrote: > The AM3358 has internal pullup/pulldown resistors available for GPIO > inputs.
