The TI-Nspire series uses a different operating system compared to Texas Instruments' other calculators. The TI-Nspire includes a file manager that lets users create and edit documents. As a result of being developed from PDA -esque devices, the TI-Nspire retains many of the same functional similarities to a computer. The likely target of this is secondary schools that make use of the TI Plus currently or have textbooks that cover the TI Plus and TI Plus lines, and to allow them to transition to the TI-Nspire line more easily. The TI-Nspire started development in However, only 20 MB and 16 MB are user-accessible respectively .
The numeric is similar in features to the TI, except with a bigger and higher resolution screen and a full keyboard. The feature that the numeric lacks is the ability to solve algebraic equations such as indefinite integrals and derivatives. The CAS is designed for college and university students, giving them the feature of calculating many algebraic equations like the Voyage and TI which the TI-Nspire was intended to replace.
However, the TI-Nspire does lack part of the ability of programming and installing additional apps that the previous models had, although a limited version of TI-BASIC is supported, along with Lua in later versions. C and assembly are only possible by Ndless. The TI-Nspire CAS calculator is capable of displaying and evaluating values symbolically, not just as floating-point numbers. It includes algebraic functions such as a symbolic differential equation solver: deSolve The body color is grey. In the United States the new calculator was listed on the TI website as a complement to the TI-Nspire with Clickpad, though it was introduced as a successor to the previous model in other countries.
The calculators were released alongside the OS 2. The keyboards on the touchpad keypads featured a different and less crowded key layout along with the touchpad, which is used for navigation. The touchpad keypads are also compatible with older calculators that are running OS 2. The new calculators that were shipped with touchpad keypads supported an optional rechargeable battery.
To reduce theft of school-owned TI-Nspire calculators, Texas Instruments also introduced the EZ-Spot Teacher Packs with a bright, easy-to-spot, " school bus yellow " frame and slide case. The hardware of both versions are the same, with the only differences being cosmetic. They have a thinner design with a thickness of 1. The device is charged via a USB cable.
TI claims that the battery requires four hours to charge, that a full charge powers the device for up to two weeks under normal daily use, and that the battery should last up to 3 years before it requires replacement.
The battery is user-replaceable. The external connectors have changed slightly.

The new wireless TI-Nspire Navigator adapter, which allows teachers to monitor students and send files, is not compatible with the previous TI-Nspire models. The keypad layout is very similar to that of the TI-Nspire Touchpad. The retail package comes in a plastic blister case and doesn't have the full manual, while the teachers edition comes in a box with a TI-Nspire CX poster for classrooms and the full manual in English and French in the US. Four models aimed for the Chinese market were launched, with specialized features. All four models have Chinese labeled keyboards.
The systems of the Chinese versions are not interchangeable with those of the international models. Like China, the continent of Europe also has models aimed for its market. These calculators include a "-T" after the CX. One of the main feature differences in the European versions is the inclusion of an exact math engine in the non-CAS version. European models also omit the WiFi adapter port from the top of the calculator. Texas Instruments offers several different versions of software for their calculators. This software allows users to share results with classmates and teachers and gives the user an emulated version of the TI-Nspire.

With the release of OS 3. It is a portable data collection device for the life sciences. The TI-Nspire Lab Cradle has three analog and two digital inputs with a sampling rate of up to , readings per second. The cradle also has 32 MB of storage space to store sensor data. The system includes the TI-Nspire cradle charging bay and the main system which looks like a wireless router. Press-to-Test is a feature that restricts access to the user's documents and certain features of the calculator for a limited time.
Its intended purpose is to prevent cheating on tests and exams. Press-to-Test is enabled by pressing a certain button combination when turning on the calculator. Press-to-Test can only be disabled by connecting to another calculator or a computer with TI-Nspire compatible software installed. Removing the batteries or pressing the reset button will not disable it.
Ti Nspire won’t connect to Mac
Ndless was developed initially by Olivier Armand and Geoffrey Anneheim and released in February for the Clickpad handheld. With Ndless, low-level operations can be accomplished, for example overclocking , allowing the handheld devices to run faster. Downgrade prevention can be defeated as well. Each subsequent OS attempts to block Ndless from operating. Most Texas Instruments calculators contain only a non-volatile read-only memory called NAND Flash and a volatile random-access memory called Synchronous dynamic random-access memory.
Previous Texas Instruments calculators had a backup button cell battery used to maintain user information, system information and time and date, between battery changes.
This allows a user to keep their information when a battery is removed. The operating system has been updated frequently since partly due to bugs and missing functions, and also to patch jailbreak exploits , one year after its release in Version 2.
Images can be included in TI-Nspire documents using the computer software. On Mac double click the downloaded file a folder should appear with the contents of the zip file. To transfer your package to a calculator:. If you are using a calculator press home 2 menu B. Particularly for exams, it is good to define programs locally so they can be used just by typing their names e.
The easy way to do this is to copy the file exam. It already has all the programs defined locally. This is because the TI-Nspire distinguishes between programs and functions. Technically poi is a program while everything else is a function. Occasionally you may find a program takes too long to complete and you want to stop it. This is particularly important when using ScriptedMath as there is a small chance that incorrect input or a bug will cause an infinite loop in a program causing it to run forever. To interrupt a calculation press and hold on. If you forget this you can always press the reset button on back of calculator , but you will lose the current document, or you can take out the batteries if you do this you may be risking corruption to other files.
To interrupt a calcuation on the computer software do the following. On Windows hold down F12 and press Enter repeatedly. On Macintosh hold down F5 and press Enter repeatedly. Getting Started Function Reference.
