You may want to refer to the TI 84 Plus CE recovery guide to help, although I don’t know if it’ll fix your situation. If your computer doesn’t recognize that something was plugged in, then you have a more serious issue. I hope one of the above issues was your problem, however if it’s still not working, You can test if your USB port is broken by replacing the battery with a charged one, then connect your calculator to your computer, if your computer recognizes something was plugged in, then data transfer is still working and there may be a bad power connection somewhere between the USB port and the battery. Have you tried replacing it or swapping your battery with someone elses? (You’ll need a small Phillips head screwdriver to take off the back) If you can’t turn it on, well, read the next paragraph. Can you try a different power source? ie instead of using the charger brick that came with the calculator, plug it into your laptop (or vice versa).Ĭan you turn on the calculator while it’s ‘charging’ using the or ‘reset’ button (the reset button is located on the back of the calculator)? If so, (and the battery indicator in the top right is orange) I’ll bet it’s a battery issue.

You Can Find Military Radars On Publicly-Available Satellite Data 13 Comments Posted in Wireless Hacks Tagged arduino, BlockDude, doom, Spark Core, STM32F103, ti, TI CC3000, ti-84, wi-fi Post navigation Or, if you’re bored with trig identities again, you can also run a port of DOOM. This is a great project to make the math workhorse of the classroom even more useful to students.
These boards made it easy to get the original Arduino-based code modified and running on the new hardware.Īfter a TI-BASIC program is loaded on the graphing calculator, it is able to input the credentials for the LAN and access the internet where all kinds of great calculator resources are available through the Global CALCnet. The boards are based around a Spark Core Wi-Fi development board which is (appropriately) built around a TI CC3000 chip and a STM32F103 microcontroller. The goal of the project is to connect the calculators directly to the Global CALCnet network without needing a separate computer as a go-between. has solved this problem with his latest project which provides Wi-Fi functionality to a TI graphing calculator, and has much greater aspirations than helping teenagers waste time in pre-calculus classes. The only downside is that the TI calculators can’t easily communicate to each other like cell phones can. In some ways this was better than a cell phone: If you wanted to play BlockDude instead of doing trig identities, this was much more discrete. Just before the days where every high school student had a cell phone, everyone in class had a TI graphing calculator.
