Hi Everyone

Apologies if these questions have been asked in other threads, but I've done a number of searches and not been able to find any references.

I have my Teensy 4.1 up and running. Now I want to add an Ethernet socket and talk to my network. I have a Sparkfun MagJack - is there any reason I can't hardwire to that? Do I need any capacitors to make it work? I saw a post which suggested a 0.1uF was required but it wasn't obvious to me which pins to connect it across.

I want to gather data with the T4.1, connect to an SMB server on my network, create a file and write data to it on the network server. Is there any code out there to help me achieve this?
