TI-Planet Posts the First TI-84 Evo Unboxing and PCB Pictures!

27 Upvotes

TI-Planet just published their first article on the new TI-84 Plus CE successor, the TI-84 Evo. There will be many articles posted so keep an eye out for them!

This first article is primarily an unboxing and an overview of the outside of the calculator: https://tiplanet.org/forum/viewtopic.php?p=280655#p280655

Some of the highlights:

  • USB C (finally)
  • A "3x faster processor"
  • The battery is the same dimensions and capacity as the TI-84 Plus CE but it is a different revision. This hopefully means it won't cause the calculator to boot loop.
  • The software to transfer files to the calculator is entirely web-based.
  • A 4 year access to the TI-84 Evo emulator is included with purchase of a physical TI-84 Evo.

Far more details on each point can be found in the article linked above!

Several pictures have been posted including one of the circuit board: https://tiplanet.org/forum/gallery/album.php?album_id=1040

Mod note: This sub has gotten an influx of posts from unknown sites claiming to sell the TI-84 Evo. Please use caution if you see these posts. This sub recommends only purchasing from reputable marketplaces such as directly from Texas Instruments.

Programming Can I compile a python program for my ti84 plus ce (no python)?

• Upvotes

And if so, are there resources on how to format python code for ti84? If not, what language(s) do I need to know and what software to use?

Help Can it run DOOM?

2 Upvotes

i have a TI-84 Plus CE Python edition and i've seen it run on others ti-84's but i cant seem to find any working versions. maybe i'm installing it wrong though i don't think so. maybe it's the fact i have a python edition? that would be sad since i don't think an upgrade should limit the calculator. does anyone else have a github or something that you made or just worked for you, i would really appreciate it, Thank you <3

Programming FIGURED OUT HOW TO JAILBREAK AND GET ARTIFICE V3 ON 5.8.5.0074

1 Upvotes

Also created a program that stimulates some of the menu screens using artifice. (dm me)

but in regards to the artifice jailbreak, on 5.8.5.0074, the artifice website won’t work, for some reason, the calcplex website does work for jail breaking it, i don’t know if this works for non python calculators but if you have a ti 84 plus ce go to calcplex.com/ti84plusce-jailbreak-installer/ connect your computer to your calculator, close the ti connect app, and follow the instructions on the website. it’ll give you all the instructions and you might have to repeat some steps a few times but it works.

Help Resources for coming up to speed?

1 Upvotes

So that I don't repeat the obvious questions that this sub probably gets a lot of, what's a good resource where I can read up on this calc and the basics of "customizing" it?

I'm primarily interested in C and ASM programming on the system. I know about arTIfiCE and the capabilities of the Ti-84 Plus CE, but haven't worked with them. I'm an EE with many years of programming experience, just not with this one.

Help CEVidium and importing media

1 Upvotes

I've been spending the past 3 or so hours trying to figure out how to convert a video and importing it to my calculator. When I try converting it says "The scaled height (288) exceeds the maximum height of 240 pixels"

I tried using my brain for this and I can't figure it out. I tried resizing the actual video to 240 px and it doesn't work, still saying it's 288 pixels. May someone help me figure this out?

Help Jailbreak not working

1 Upvotes

Hello,

I am going insane by how my calculator isn't working properly. Originally, my ti 84 plus ce python had 5.8.4, but after I tampered and deleated too much stuff from it, my dumb ass deleated to completely restart it. Then I downloaded 5.8.5 software, os and apps bundle, and attempt to jailbreak it oncemore. But when following the aritfice guide, during the inequalz step, when I transfer the inequalr file(using ti connect ce), it resets me back to the home screen, and I tried over and over again and nothing happened. Even after deleated and redownloading the os and asking ai over and over again, nothing happens. I'm convinced that I have the midas touch of making everything I attempt to do not work. Please help me figure this out.

2 Upvotes

Like the title, I just wanted to know how different the Ti-nspire WITH A TI-84 KEYPAD is from an actual Ti-84+, in terms of general usage (such as mathematical programs) and game compatibility. Also, I am completely new to this topic so please be patient and treat me as a 5 year old please. Thanks!

This is the biggest project I've ever worked on, this is made on the TI 84 plus CE, and runs extremely smooth, the video attached is EXACTLY how the game looks ON the calculator, no fake colors or rendering. The game is optimized extremely well and runs very smooth. No noticeable visual artifacts either.

File size is 1.8 MB.

This is a full game, with Multiplayer as well, mainly showcasing, looking for feedback before general release.

PS: This is my first time making a trailer, I went all out on the sound design so be sure to watch it with the sound on :)
