• 2Activation Process

To use Code Composer Studio you need a license. To get a license you need to activate. There are a number of different license options in CCS, these are listed below. For free CCS licenses, activation may occur directly in CCS itself. For most purchased licenses you will be provided with an activation ID and you will use the www.ti.com/activatesoftware to generate your license file.

IMPORTANT UPDATE: Note that full licenses are now available at no cost. See the important update on the Licensing_-_CCS page.

When you run CCS it will detect if you have a license file installed. If it does not find a license file it will bring up a dialog with instructions on how to obtain a license file to use. This license dialog will also display your host ID (MAC address) which you may need during the activation process.

Note: If you already have a license file you can just point to it via the actions in 'Step 2' under 'ACTIVATE'.

Once activation is complete, you will now return to CCS. You should see (Licensed) in the title bar. If you see (Unlicensed) then you will see the activation dialog the next time you start CCS, requesting one of the following licensing options be chosen:

ACTIVATE

This will provide options to activate Code Composer Studio with an activation code, license file, or floating license. Select the option for ‘ACTIVATE’ and hit the ‘Next’ button at the bottom of the dialog box to continue to the activation dialog. Then follow the steps below:

Step 1 – Generate License File: Choose the license type

(Note: If you already have a valid license file, or have access to a floating license on a server, you can skip this step and go to Step 2):

• Node-Locked License: Record one of your MAC addresses (displayed above the ‘Register’ button). A MAC address will be needed to generate a license. Then press the ‘Register’ button. This will open a web page in your web browser to guide you through the steps of generating a license file with your activation code and MAC address. The generated license file will then be e-mailed to you.

• Floating License: Select the ‘Register’ button to generate a license for a multi-user floating license. This will open a web page in your web browser to guide you through the steps of generating a license file with your activation code. The generated license file will then be e-mailed to you along with instructions on how to setup the license on a server.

• Using simulators
• Using Code Composer Studio for Linux/Android application development using GDB

Simply select the option for ‘FREE LICENSE’ and hit the ‘Finish’ button at the bottom of the dialog box to continue.CODE SIZE LIMITED: This will activate Code Composer Studio with a FREE license for MSP430 with no time restriction, but with a code size limit of 16 KB. Simply select the option for ‘CODE SIZE LIMITED’ and hit the ‘Finish’ button at the bottom of the dialog box to continue.

CODE SIZE LIMITED

This will activate Code Composer Studio with a FREE license for MSP430 with no time restriction, but with a code size limit of 16 KB. Simply select the option for ‘CODE SIZE LIMITED’ and hit the ‘Finish’ button at the bottom of the dialog box to continue.

Activation without Internet Access

If CCS is being installed on a machine without direct internet access, record the Host ID as mentioned above and either go to a machine which does have internet access or provide the HostID to someone who can access the internet on your behalf. If you have purchased CCS and have an activation ID then go to the registration page and follow the steps above to generate a license. If you are looking to activate the free bundle license then use this link. Be sure to enter the Host ID for the machine you wish to use CCS on and if you are registering on behalf of someone, you can enter their e-mail address to have the license file sent directly to them (or to someone that can then forward it to the proper person). Once the license file is received, copy the file on to the machine where CCS needs to be activated and then specify the path to the file in the 'Activate Code Composer Studio' dialog to complete the activation.

The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004. There is no original TI-84, only the TI-84 Plus and TI-84 Plus Silver Edition models. The TI-84 Plus is an enhanced version of the TI-83 Plus. The key-by-key correspondence is relatively the same, but the 84 features some improved hardware. The archive (ROM) is about 3 times as large, and CPU about 2.5 times as fast (over the TI-83 and TI-83 Plus). A USB port and built-in clock functionality were also added. The USB port on the TI-84 Plus series is USB On-The-Go compliant, similar to the next generation TI-Nspire calculator, which supports connecting to USB based data collection devices and probes, and supports device to device transfers over USB rather than over the serial link port.^[1].

In 2015, Texas Instruments released the TI-84 Plus T in the Netherlands. This model is very similar to the original TI-84 Plus, but features an LED to indicate whether or not the calculator is in Exam Mode. The hardware of the TI-84 Plus T is similar to the TI-84 Plus Silver Edition, with 96 16 kB pages of archive memory, for a total of 1540 kB. However, unlike the TI-84 Plus, the TI-84 Plus T does not allow users to execute assembly programs. The TI-84 Plus T has 2 different Exam Modes available with different levels of restrictiveness. The most restrictive level does not allow for any existing programs to be accessed, and does not allow any new programs to be created. This mode makes the LED blink green. The second, more moderate Exam Mode is the same, apart from three additional applications being allowed (PlySmlt2, Inequalz and Conics). This mode makes the LED blink orange.

Versions[edit]

TI-84 Plus Silver Edition[edit]

The TI-84 Plus Silver Edition was released in 2004 as an upgrade to the TI-83 Plus. Like the TI-83 Plus Silver Edition, it features a 15 MHzZilog Z80 processor and 24 kB user available RAM. The chip has 128 kB, but TI has not made an OS that uses all of it. Newer calculators have a RAM chip that is only 48 kB. All calculators with the letter H or later as the last letter in the serial code have fewer ram pages, causing some programs to not run correctly.^[2] There is 1.5 MB of user-accessible Flash ROM. Like the standard TI-84 Plus, the Silver Edition includes a built-in USB port, a built-in clock, and assembly support. It uses 4 AAA batteries and a backup button cell battery. The TI-84 Plus Silver Edition comes preloaded with a variety of applications. These programs are also available for the TI-84 Plus, but some must be downloaded separately from TI's website. It is manufactured by Kinpo Electronics.

TI offers a special yellow version of the TI-84 Plus, inscribed with the words 'School Property', for schools to loan out to students. This special design was produced in effort to combat theft.^[3] Owners can buy other interchangeable colored face-plates and slide-cases online. A kickstand-style slide case and other accessories are also available. Although graphing calculators have been called inexpensive in education reform research,^[4] the TI-84 Plus Silver Edition cost $139.00 as of 2013 on the TI online store. This calculator has been discontinued in favor of the TI-84 Plus C Silver Edition.

In 2011, TI launched for the French market a miniaturized version of the TI-84 Plus : the TI-84 Pocket.fr.In 2012, TI launched for the Asian market a miniaturized version of the TI-84 Plus Silver Edition : the TI-84 Plus Pocket SE.

TI-84 Plus C Silver Edition[edit]

The TI-84 Plus C Silver Edition was first publicly referenced in October 2012 in a tweet from TI.^[5][6] Even though this tweet had gone unnoticed, in November 2012, it was discovered^[7] through a leak from a pilot class (the Cemetech user that leaked it, 0rac343, was part of said class) that TI was developing a color-screen TI-84 Plus, tentatively called the TI-84 Plus C Silver Edition. It has a high-resolution 320x240-pixel color screen driven by the Ilitek ILI9335 LCD controller, a modified version of the 2.55MP operating system, a removable 1200mAh rechargeable lithium-ion battery and keystroke compatibility with existing math and programming tools. It has the standard 2.5mm I/O (DBUS) port and a mini-USB port for connectivity and charging. More details about the calculator's math and programming features were published when TI began distributing review models in February 2013,^[8] and even more when the calculator was released in 2013. This calculator was not received well by everyone as it is fairly slow (to the point of missing key presses and making the program editor unusable) compared to the older monochrome ones. This was mainly due to the fact that TI used the same TA3 ASIC as in late model TI-84 Plus/SE calculators, meaning it still used a 6/15 MHz dual-mode Z80. On 30 October 2014, Cemetech user Val managed to overclock their TI-84 Plus C Silver Edition by replacing resistor R07D with a 5 kiloohm potentiometer. Soon after, Botboy3000 showed off his version with a color coded speed control knob. These experiments proved the calculator was perfectly stable up to a blazing 22Mhz. It is still unclear why TI limited it, but one possibility is that they wanted to sell more calculators later (namely the more powerful successor, the TI-84 Plus CE). The TI-84 Plus C Silver Edition is still the last calculator to have a version of the Christopher 'Kerm Martian' Mitchell's famous Doors CS GUI that, which despite the calculator's overall sluggishness, makes it an attractive purchase especially on the used calculator market. Due to being able to run 3rd party operating systems (such as KnightOS) and community-produced apps (both things which the CE cannot do), this calculator is the last super-hackable calculator from TI.

TI-84 Plus CE and TI-84 Plus CE-T[edit]

The TI-84 Plus CE was publicly previewed by TI Education in January 2015,^[9] and released Spring 2015. The calculator retains the 320x240-pixel color screen, rechargeable battery, and key layout of the TI-84 Plus C Silver Edition, while removing the 2.5mm I/O ('DBUS') linkport and moving the USB port and charging LED to the right side of the handheld. The calculator's OS 5.x is incompatible with the TI-84 Plus C Silver Edition's hardware. The calculator has 154KB of user-accessible RAM and 3.0MB of Archive memory. It uses the eZ80 processor from Zilog, making all Z80 assembly programs from previous 84 Plus series calculators incompatible. The CE comes in multiple colors, Classic (black), Silver Linings, Radical Red, True Blue, Denim (navy blue), Lightning (light blue), Plum Pi (purple), Positively Pink (as of March 2015), Golden Ratio, and Bright White (as of June, 2016). Like the rest of the 84 Plus series, it is allowed on most standardized tests.^[10] The calculator comes programmed with seven different languages (English, French, German, Dutch, Portuguese, Spanish, and Swedish). In 2016, the TI-84 Plus CE-T was released for the European educational market. The onlysignificant difference from the CE model is the addition of an LED that blinks while the calculator is in Press-to-Test mode.CE calculators revision M and later (manufactured on and after April 2019) contain a faster flash chip (Winbond 25Q32JVSIQ) than previous revisions, which contained a Winbond W29GL032C. Due to this change, more recent revisions have seen a significant improvement in overall speed.

Software[edit]

There are three different types of programs which can be downloaded or programmed into the calculators: TI-BASIC, Z80 assembly language, and Flash applications (also written in Z80 assembly). The TI84+CE is different in that programs are written in TI-BASIC, eZ80 assembly language, or in the C programming language. In addition, there are programs available that are able to compile or interpret other programming languages. Also, there are several languages developed by community members for the calculators, notably ICE, which is for the TI84+CE, and Axe, which is for the TI84+ and TI84+SE. There are a wide range of applications that this produces, from science classes, to games, to calculus to note taking (when put together with a separately sold keyboard).The TI-84 Plus Series is exactly like its predecessor in that it can be used on the SAT and ACT examinations as well as International Baccalaureate examinations. However, in some cases those administering the exam may reset the calculator's memory beforehand to prevent cheating through the use of built in programs or other data.^[11]

When OS 2.30 was initially released, users noticed the speed of graphing was greatly reduced. The explanation was that the update added asymptote checking in graphing.^[12]

In January 2006, Texas Instruments released v2.40 of the operating system for the TI-84 Plus series. The most noticeable addition to the new OS was the 'Press-To-Test' feature that allowed a teacher to disable any programs installed on the calculator, so they cannot be used on tests, etc.^[13] As of OS version 2.53MP which was released in February 2010, support was added for prettyprinted expressions. However, some programs stopped working correctly in this OS version, or were running slower.^[14] The current OS version is 2.55MP which was released in January 2011.^[15]

In July 2009, a community-made patch was released which allowed user-made operating systems to be easily uploaded onto the TI-84 plus series. Shortly after the patch was developed, the RSA keys for the calculator's operating system were factored via the General number field sieve (GNFS) algorithm, making a software patch unnecessary. In response to this, Texas Instruments released a newer hardware revision which only accepts other, stronger RSA keys, making it harder to load user-made operating systems or older TI operating systems (2.53MP and earlier). The community has found a way around the newest limitation by discovering a way to revert to older versions of the boot code.^[16]

Critics point out that the basic design of the TI-84 has not changed since it was released in 2004, contrary to the trend of rapid design change occurring in other areas of electronics manufacturing.^[17][18]

Programming[edit]

The TI-84 Plus is based heavily on its predecessor, the TI-83 Plus. As with all other calculators in the series, the TI-84 Plus supports native Z80 assembly as well as TI's interpreted, BASIC-like language for calculators, dubbed TI-BASIC. Programming for the TI-84 Plus is nearly identical to programming for the TI-83 Plus, with a few new functions in both TI-BASIC and the calculator's assembly support that do not exist on earlier models and OS versions. Several attempts have been made at creating a C to Zilog Z80 assembly assemblers, such as SDCC.^[20]

The TI84+CE series can be programmed in TI-BASIC, eZ80 assembly, or with the C programming language.

The TI-84 Plus calculators' dialect of TI-BASIC is the same as that of the TI-83 Plus series, but with a few more commands including ones for date and time.
