Found the problem!

It was running too fast - 16MHz. The max on 3.3v is 10MHz. Using divide by 8 fuse and quick change to the code corrected the problem.

Thought I'd let everyone know...

Checked with a scope and meter. The pins at the uC stay at 1.7 Volts. They never go to a true hi (3.3) or low.

Other than what has been suggested already, anything else to look at?

Thanks all!

I've also tried with an ATMEGA88 - which is pin compatible, at least for the pins I am using!

Still no good.

If I bypass the uC and bring ground to the LED, it does turn on, but will not turn o ...

Hello all.

I have a simple program and all I want to do is to turn on a couple of LED's using the Atmega328PB. Even when I use the sample program and add the code they still wont turn on.
