TI NSPIRE OS SERIAL
He’s taken that up a notch with a helping hand from Arduino. An Arduino board is used to connect the serial communications from the calculator to an Internet connected PC via the Arduino’s USB capabilities. We looked in on CALCnet in December when it was being used to create local area networks with the adding machines. It also provides the option of worldwide multiplayer functionality for games ported to the device such as Scorched Earth and Tetris. Global CALCnet lets you connect your TI graphic calculator to the Internet and use your favorite services like instant messaging and Internet relay chat.
TI NSPIRE OS FULL
All of the source for the kernel and bootloader are available on ’s Github and updates on his blog. After the break, check out a video of text-based browsing using a full keyboard.Ĭontinue reading “Linux On A Nspire CAS CX Calculator” → Posted in Featured, Linux Hacks Tagged graphing calculator, linux, ti-nspire Global CALCnet: Your TI-83 Just Acquired Internet It looks like this calculator is on the way to being a handheld Linux device. The calculator runs a SSH server for remote access, and graphical browsing is in the works. At this point, the calculator can connect to the internet and browse using a text-based browser: Links. This allows for a USB keyboard and Wifi dongle to be connected. also managed to get USB host mode working on the calculator. It also allows for peeking and poking at memory for debugging. He’s developed an in-place bootloader that allows a kernel to be loaded from within the stock Nspire OS. has successfully run a Linux kernel on the ARM based Nspire CAS CX graphing calculator. It’s great to see Linux running on a device in a way that was never intended. We’re not exactly sure what to do with Linux on a graphing calculator, but it is a neat demonstration.Ĭontinue reading “Running Debian On A Graphing Calculator” → Posted in handhelds hacks, Linux Hacks Tagged arm, debian, debootstrap, linux, ndless, qemu, ti-nspire As the video after the break demonstrates, this leaves you with a shell on the calculator. With the root filesystem on a USB flash drive, Ndless runs the Linux loader, which starts the kernel, mounts the root filesystem, and boots in to a Debian system in about two minutes.
TI NSPIRE OS INSTALL
This allows you to install whatever packages are needed via apt, before transitioning to the calculator itself.
The root filesystem is built on a PC using debootstrap and the QEMU ARM emulator. In this case, Ndless is used to load the Linux kernel. Ndless also includes a full SDK, emulator, and debugger for developing apps.
TI NSPIRE OS CODE
The process uses Ndless, a jailbreak which allows code to run at a low level on the device.
managed to get Debian Linux running on a TI-Nspire calculator, and has written a guide explaining how it’s done. While the ubiquitous TI-83 still runs off an ancient Zilog Z80 processor, the newer TI-Nspire series of graphing calculators uses modern ARM devices.
TI NSPIRE OS ANDROID
Posted in Android Hacks Tagged android, Android Donut, calculator, nSpire CX, ti-nspire It is, however, the perfect example that you don’t need the latest and greatest phone to run Android. He can play some 2D games on it, and the ability to browse the web with a calculator is interesting, to say the least. Still, even with a 150MHz processor and 64MB of RAM – far less than what was found in phones that shipped with Donut – is still getting surprisingly good performance out of his calculator. Yes, can still run a TI-83 emulator on his calculator, but finding an app that’s compatible with his version of Android is a challenge. The vast majority of calculator emulators on the Google Play store require Android version 2.2 and up. While has Android Donut running along with most of the 1.6 apps, a terminal emulator, keyboard, WiFi, USB, and Bluetooth running, this calculator-come-Android isn’t as useful as you think it would be. Everything he’s done is available on the GitHub for this project, and with the instructions on the xda developers post, anyone can get a version of Android running on this TI calculator. With the right development environment, managed to get the full Android stack up and running and ironed the bugs out. Without the ability to run native applications on this calculator, would be locked out of his platform of choice without the work of the TI calculator community and Ndless, the SDK for this series of calculators.
Unlike just about every other TI calculator, homebrew developers are locked out of the nSpire CX and CX CAS. He’s running Android Donut on a TI nSpire CX graphing calculator. He’s convinced Android will run on extremely low-end hardware, and after a great deal of searching, hit upon a great combination. Is trying to fight a misconception that Android only runs on fast, powerful smartphones.
