'''Code Composer Studio''' (CCStudio or CCS) is an [[integrated development environment]] for developing applications for [[Texas Instruments]] embedded processors.

[[Texas Instruments]] embedded processors include [[Texas Instruments TMS320|TMS320]] DSPs, [[OMAP]] System-on-a-chip, [[Texas Instruments DaVinci|DaVinci]] System-on-a-chip, [[Sitara ARM Processor|Sitara]] applications processors, [[Hercules (processors)|Hercules]] microcontrollers, Tiva/Stellaris microcontrollers and [[MSP430]] microcontrollers.

Code Composer Studio includes a real time kernel called [[DSP/BIOS]] and its later inception [[SYS/BIOS]] and is primarily designed as for embedded project design and low-level (baremetal) [[JTAG]] based debugging. However, the latest releases are based on unmodified versions of the [[Eclipse (software)|Eclipse]] open source IDE, which can be easily extended to include support for OS level application debug (Linux, Android, Windows Embedded) and open source compiler suites such as [[GNU_Compiler_Collection|GCC]].

Code Composer Studio is primarily designed for embedded project design and low-level (baremetal) [[JTAG]] based debugging. Versions 4.0 to 12.8 are based on the [[Eclipse (software)|Eclipse]] open source IDE, which can be easily extended to include support for OS level application debug ([[Linux]], [[Android (operating system)|Android]], [[Windows Embedded]]) and open source compiler suites such as [[GNU Compiler Collection|GCC]]. Starting with Version 20 in December 2024, CCS is based on the [[Eclipse Theia]] platform and IDE.<ref>ti.com [https://downloads.ti.com/ccs/esd/CCSv20/ ''Introduction to CCS v20.'']</ref>

Early versions included a real time [[Kernel (operating system)|kernel]] called [[DSP/BIOS]] and its later inception SYS/BIOS. Currently, the successor to these tools, the [[TI-RTOS]] embedded tools ecosystem, is available for downloading as a free plugin to Code Composer Studio.

== History ==

Originally Code Composer Studio was afirst productdeveloped fromunder athe companyname calledCode Composer by the software company GO DSP, located in Toronto, ON, [[Canada]], and itwhich was acquired by [[Texas Instruments|TI]] in 1997.<ref>''[{{cite web |title=Texas Instruments to Acquire GO DSP Corporation |url=http://www.ti.com/corp/docs/presshistory/company/1997/c97093.shtml TI|publisher=Texas PressInstruments release]''<|archive-url=https:/ref>/web.archive.org/web/20160304054738/http://www.ti.com/corp/docs/presshistory/company/1997/c97093.shtml After|archive-date=2016-03-04 the acquisition, Code Composer was bundled with a real|date=1997-time kernel12-18 named DSP|url-status=dead}}</BIOS<ref>'' Integration with [[SYS/BIOS#History|History of SYSDSP/BIOS]]''</ref> was added to Code Composer, and itsCode nameComposer was appendedrebranded withas Code Composer Studio.{{cn|date=May 2024}}

CCS releases up until 3.3 were based on a proprietary interface,. but [[Texas Instruments|TI]] wasdeveloped alreadya workingnew in parallel on the[[Integrated development of an environment|IDE]] based on the open-source [[Eclipse (software)|Eclipse]]. This IDE was, named Code Composer Essentials (CCE), andthat was designed for the [[MSP430]] line of microcontrollers. This expertise was used to completely overhaul the previous CCS and startingBeginning with release 4.0, all new versions areof CCS would also use an interface based onupon [[Eclipse (software)|Eclipse]].

Code Composer was originally developed for [[Digital signal processor|DSP]] development, thereforeand one of its main differentiators at the time was the availability offeatured graphical visualization tools (XY graphs, FFT magnitude and phase, constellation, raw image visualization) and support for visualizing memory in several [[Computer number format|numeric formats]] (decimal, floating-point).{{cn|date=May 2024}}

In 2015, a [[cloud computing]] version of CCS was introduced and is part of the suite TI Cloud Tools, which also hosts Resource Explorer and Pinmux.

==Licensing==

{{Update section|date=April 2018}}

Over the years CCS followed the trend of the software industry for reduced and free-of-charge software licensing, reflected across the releases:

Over the years, CCS followed the trend of the software industry for reduced and free-of-charge software licensing, reflected across the releases:

*CCS releases up to 2.x were separated per device family, i.e., every device family required the purchase of a separate license and a separate software Each license's SRP was US$3,600.00 (apart from release 2.3, which was about US$4,500.00)

*Starting with releases 3.x, all device families were included in the same license (then called Platinum). The license`'s SRP was the same (US$3,600.00). There was a C2x-only limited license that retailed for US$600.00.

*Starting with release 4.x, CCS can be used for free in several scenarios that include development boards, software device simulators and even the use of a standalone emulator named XDS100.<ref>[http://processors.wiki.ti.com/index.php/Licensing_-_CCS CCS license page at TI wiki]</ref>. Also, it can be used with a codesizecode size limitation of 16kB on [[MSP430]] devices. This release also introduced the floating license, which can be installed on a server and be used across a company's or university's Intranet at almost the cost of a full license.

**A full license for CCS release 4.x had an SRP of US$1,995.00 and a microcontroller-only license was US$495.00. This microcontroller license covered all [[MSP430]], Stellaris and C2x devices.

**A full license for CCS releases 5.x and 6.x has an SRP of US$495.00 and the microcontroller-only license ceased to exist.<ref>[http://processors.wiki.ti.com/index.php/Licensing_-_CCSv6 CCSv6 license page at TI wiki]</ref>.

**Starting in September 2016, the floating license model ceased to exist.

**For CCS release 7.x the paid license ceased to exist. The software and all its components are distributed with a TSPA license.<ref name="TSPA_license"/>

***The free license model was also retrofitted to all public CCS releases since v4.

For all releases an annual paid subscription fee was required to grant updates for upcoming major releases.

*Starting in August 2015, the concept of subscription fee ceased to exist.

==JTAG Debug probe support==

Historically CCS supported only [[JTAG]] debug probes from [[Texas Instruments|TI]] - also called XDS emulators.<ref>[http://http://www.ti.com/jtag JTAG emulators at www.ti.com]</ref>. The XDS510-class and the more advanced XDS560-class emulators are supported across all releases, but the new low-cost XDS100-class emulator started to be supported starting with the latest patches to release 3.3.<ref name="XDS100">[{{Cite web |url=http://processors.wiki.ti.com/index.php/Xds100 |title=XDS100 page at TI wiki] |access-date=2014-04-28 |archive-url=https://web.archive.org/web/20140428020828/http://processors.wiki.ti.com/index.php/XDS100 |archive-date=2014-04-28 |url-status=dead }}</ref>

Releases 4.x added support for an updated design of the existing XDS100-class emulator (called XDS100v2) and, in release 4.2, added support for an updated design of the XDS560-class emulator (called XDS560v2).<ref name="XDS100"/><ref name="CCSDownload">[http://processors.wiki.ti.com/index.php/Download_CCS CCS releases at TI wiki]</ref>

Release 5.2 added support for the new XDS200-class emulators.<ref>[{{Cite web |url=http://processors.wiki.ti.com/index.php/Xds200 |title=XDS200 page at TI wiki] |access-date=2014-04-28 |archive-url=https://web.archive.org/web/20140428060451/http://processors.wiki.ti.com/index.php/Xds200 |archive-date=2014-04-28 |url-status=dead }}</ref>

Up until release 4.x, CCS supported only XDS emulators. With the integration of [[MSP430]] and Stellaris microcontrollers, support was added for their respective [[JTAG]] debug probes: MSP-FET430 (both parallel and USB versions) and ICDI.<ref name="CCSDownload"/>

Release 5.x also saw the introduction of Beta support for Jlink[[J-LINK|J-Link]] [[JTAG]] debug probes from [[Segger_Microcontroller_SystemsSegger Microcontroller Systems|Segger]].<ref name="Segger">[http://processors.wiki.ti.com/index.php/J-Link_Emulator_Support Segger Jlink support page at TI wiki]</ref>

Release 6.0.x saw the introduction of the new MSP-FET debug probe for MSP430 devices<ref>[http://www.ti.com/tool/MSP-FET MSP-FET page at TI website]</ref> and the new XDS200-class<ref>[http://www.ti.com/tool/TMDSEMU200-U XDS200 page at TI website]</ref> of debug probes for processors.

Release 6.1.x saw the introduction of the new XDS110-class<ref name="XDS110">[http://processors.wiki.ti.com/index.php/XDS110 XDS110 page at TI wiki]</ref> of debug probes for processors. It also saw the migration to full production support for [[J-LINK|J-Link]] [[JTAG]] debug probes from [[Segger Microcontroller Systems|Segger]].<ref name="Segger" />

Release 7.x saw the integration of [[J-LINK|J-Link]] [[JTAG]] debug probes from [[Segger Microcontroller Systems|Segger]]<ref name="Segger" /> directly in the CCS installer. It is also the first release to support the standalone version of XDS110.<ref name="XDS110" />

64-bit releases do not support Spectrum Digital XDS510USB JTAG debuggers.
