    No, there were no SMT components populated...I added them. It's good practice to terminate the center tap on both sides of the Ethernet magnetics. The line side is typically shunted to ground through a 50- or 75-ohm...

    Okay, I take back the "1kV" comment. Looking at the datasheet in the link defragster posted, there's a 2kV 1000pF cap in the package already.

    Can confirm. No ballast resistor needed for the LED. There are pads for tying the Ethernet connector shield (and by extension the wire side of the magnetics) to ground, as well as the circuit side center taps of the...

    @manitou Thanks for that! Well heck, looks like everything's done then. Is there anything useful I can add at this point or should I move on to something else? Maybe work on getting the existing Arduino Ethernet...

    Also, before I totally reinvent the wheel, are there any existing functions/macros for things like setting the pin mux or pin configuration registers? What would be the most recent low-level library with good examples...

    So I'm starting work on the Ethernet interface now. In the past (for FlexIO and clock tree generation), my approach has been to start with known working code in MCUXpresso and then move that over to Arduino-land. For...
