The CD-ROM in the FET kit includes both the IAR Kickstart Embedded Workbench IDE with a 4kB C-compiler and the TI Code Composer Essentials (CCE) IDE with an 8kB C-compiler. CCE V2.0 is available for purchase from Texas Instruments. It is built on the open source Eclipse based platform which allows user created plug-ins, supports all MSP430 devices, and provides unparalleled debugging performance. Currently, CCE provides the best-in-class code speed optimization relative to all other compilers available for the MSP430. Code execution speed is vital for low power applications since every single cycle required to complete a task consumes a battery life.
