I'm pretty fluent in TI-BASIC and C/C++ and I figured the next step up is learning eZ80 assembly, especially since I wanted to try my hand at making some 3D applications which would be very sluggish/difficult in C without major optimization and nearly impossible in BASIC. Any links to resources would be really nice, thanks in advance!
Most regular z80 tutorials can get you started on the basics since the ez80 is a relative of it. But none of that code will actually work on an ez80 based calculator without modification unfortunately.
I would recommend reading some of the manuals, namely this one: http://www.zilog.com/docs/um0077.pdf
You can also study example code from the toolchain: https://github.com/CE-Programming/toolchain/tree/master/src
For an assembler there are 2 options really: https://github.com/jacobly0/fasmg-ez80 and https://github.com/alberthdev/spasm-ng
EDIT (thanks Adriweb) - Also can't forget the asm-docs repo: https://github.com/CE-Programming/asm-docs
fasmg is newer with lots of features while SPASM-NG is based on the z80 assembler and may be easier to use for beginners? (Don't flame me
). I should have asked what OS you use? Win/Mac/Linux/etc? There may be different options.
The best tip is to become familiar with the hardware platform, for that WikiTI is the best source: https://wikiti.brandonw.net/index.php?title=Calculator_Documentation#TI-84_Plus_CE.5B-T.5D.2C_TI-83_Premium_CE
An example Hello World may look like this (SPASM):

"My world is Black & White. But if I blink fast enough, I see it in Grayscale."
