C2000-CGT

The TI C2000 C/C++ Compiler and Assembly Language Tools support development of applications for TI C2000 Microcontroller platforms, including the Concerto (F28M3xx), Piccolo (280xx), Delfino Floating-Point (283xx), and C2000 Fixed-Point (2823x/280x/281x) Microcontroller devices.

Code Composer Studio is the Integrated Development Environment (IDE) for TI embedded devices.  If you are looking to develop on a TI embedded device it is recommended to start by downloading Code Composer Studio as it includes the TI compilers.  If you are already a user of Code Composer Studio the best way to update the compiler is to go to the Help menu and select to install compilers (please see Getting compiler updates in CCS for more details).

TI Compiler Support

TI has an active, responsive E2E™ community, where support is available for TI compilers.

• E2E development tools forum

• Perform cyclic redundancy checking using linker-generated CRC tables

Long-term and short-term support

Long-term support (LTS) releases are actively maintained for approximately two years with reported defects being repaired as follows:

• Production stop defects are addressed within 2 weeks,
• Critical defects are addressed within 90 days, and
• Defect repairs are proactively applied to each release stream

Short-term support (STS) releases are only supported until the next release becomes available meaning that:

• Only production stop defects may cause patch releases to be created,
• Patch releases for STS releases will not be planned, and
• Defect repairs will not be proactively applied to each release stream
• For more information about the distinction between LTS and STS compiler releases, please see the article: Introduction to LTS and STS Compiler Releases
