So, you are sending magic numbers to a mystery device which may or may not be responding to one or more of those magic numbers. You are expecting some sort of output from that mystery device but you are not getting that output and you can't figure out why.You are the one who knows what the mystery device is, what information you are supposed to send it, and how it is supposed to respond but you can't determine why it isn't working the way you think it should. We know nothing about your mystery device except that it is some sort of serial LED display. How do you expect us to help?

Well, basic UART should be pretty universal amongst all devices. You send data, you wait for the response back. What my mystery device is really shouldn't matter too much, assuming the call and response information I have provided is correct. People have made suggestions which made me re-examine the way I have my code structured. that is helpful to me, and what I am really looking for in terms of help. Other then that, there really isnt much else you can do unless you want want to start reading through the datasheet(s) themselves. I'm learning, so I want to handle the datasheet business myself. The device is a 4D uOLED-160-G1. The datasheet I am primarily referencing is here
