I got curious about the Raspberry Pi serial connection recently so went about getting it to work on mine. It’s mostly for fun but I can see the benefit when I want to find out the IP address of my Pi without having a monitor and keyboard on hand. Plus, I this would benefit the classes I plan on running as I may not have extra monitor and keyboard for the classes.
I managed to find my I2C OLED display when I was cleaning up my place. As I currently have a S3 storage cluster project ongoing, I figured now would be a great time to get it working so I can attach an OLED display to each of the Raspberry Pis so I can get their status on a glance. Below are the steps I used to get it working on Rasbian Lite.
