Arming developers with more software and tool options, Texas Instruments announced the availability of its newest Stellaris microcontroller (MCU) Robotic Evaluation Platform (EVALBOT). The new mini-robot platform within TI’s embedded processing portfolio provides developers the flexibility to choose from a variety of software tool chains so they can fully access the features of the Stellaris Cortex-M3 MCU in their preferred environment. The updated Stellaris EVALBOT is also preloaded with a StellarisWare® application, and the kits now include more example projects in source code, including a demo that enables developers to more easily experiment with the kit’s expansion port that supports TI wireless evaluation modules. With EVALBOT, developers can experience the Stellaris MCU in a real-world application that leverages the processor's integrated 10/100 Ethernet MAC/PHY, USB On-The-Go, CAN, and motion control capabilities.
