What made the matter worse is they passed the issue off as if it were still present in modern OSes! With the video gaining almost a quarter of a million views, TI thought they'd need to take some drastic measures to uphold their Exam Mode security reputation.
One big factor in the decision to ban ASM was due to a video created by a student and a teacher that showed the exact steps to bypass a Test Mode restriction in OS 5.2.2, an obsolete, 3 year old OS. With the decision planned to go global, this means that any program written in ASM or C will not run on any CE operating on the newest TI OS 5.5.1 or higher! Just a few days ago, TI Education announced that the most recent OS for theTI-84 Plus CE (-T) and TI-83 Premium CE removes the ability for the calculator to run any Assembly (ASM) code. His video showing the whole build in detail is below the break, so if you fancy a calculator with cellular connectivity, here’s your opportunity.If you want to get up to speed quickly, I made a video that summarizes the vast majority of all the information I've gathered across dozens of sources! There's a lot of information that wasn't covered in this thread so check it out if you want to know everything!
#Doom for ti 84 plus ce serial
A concealed switch allows the cellphone to be turned off to preserve battery life.The calculator talks to the Arduino via a slightly unsightly external serial cable. The calculator’s 4 AAA cells could not supply enough power on their own, so he’s supplemented them with a couple more, and replaced the alkaline cells with rechargeables. He’s integrated a cellphone module into his TI-84 calculator, and though perhaps it won’t be knocking Apple or Samsung off their pedestals just yet, it’s fully functional and both makes and receives calls.To perform this feat he’s taken the cellphone module and one of the tiniest of Arduino boards, and fitted them in the space beneath the TI-84’s keyboard by removing as much extraneous plastic as he could. Even the feature phones of a couple of decades ago bundled some form of calculator, so that particular task has joined the inevitable convergence of functions into the one device.For Scott Howie though. For many of us, a calculator is something we run as an app on our mobile phones. Of course, the PCB for the LED cube is designed as an Arduino shield for ease of prototyping, but make no mistake: this is an LED cube controlled by a calculator. The electronics are simple, and just a few 595s and transistors, but this LED cube is taking serial data directly from the link cable on a graphing calculator.
The most impressive, at least from a soldering standpoint, is their. They’re the main driving force behind turning these pocket computers with truly terrible displays into usable computing platforms.As you would expect from any booth, Cemetech brought out the goods demonstrating exactly what a graphing calculator can do.
These things have been around in one form or another for almost three decades, and for a lot of budding hackers out there, this was the first computer they owned and had complete access to.As hacking graphing calculators is a favorite for Maker Faires, we were pleased make it out to this year’s World Maker Faire in New York last weekend. The most important computing platform for teaching kids programming is the Texas Instruments graphing calculator. It’s not Apple IIs, and it’s not Raspberry Pis.
