Hi Ankita,

I checked my GPIO pin with a DVM (rather than a scope). However, I'm confident it worked.

If you can drive an LED directly from the same GPIO pin (that's what you tired - yes?) then you can be confident the logic level is appearing on the GPIO pin. I'm now suspecting your scope setup if that's not showing the level change.

Cheers,

Alex
