IAR announces support for Stellaris MCUs

IAR Systems has announced that IAR Embedded Workbench for ARM and IAR Powerpac for ARM feature support for Texas Instruments' ARM Cortex-M3-based Stellaris microcontroller (MCU) family.

New configuration files, flash loaders and project examples have been added to IAR Embedded Workbench for ARM for the new range of Stellaris MCUs.

The device specific support achieved by these additions makes it quick and easy to get started with a project and allows the user to focus on application development.

New IAR Powerpac Board Support Packages (BSPs) will be made available for the three new kits (EKI-LM3S9B90, EKI-LM3S9B92, and DK-LM3S9B96) from Texas Instruments.

The BSPs include all the drivers and low level routines needed for the operating system and communication software to interface the hardware and access the peripherals on the boards.

IAR Embedded Workbench for ARM, is a set of sophisticated and easy-to-use development tools.

It incorporates an ARM Cortex-M3 C/C++ compiler, assembler, linker, librarian, text editor, project manager, and debugger combined in an integrated development environment (IDE) for programming embedded applications.

In addition to supporting debugging through the JTAG port, IAR Embedded Workbench also supports SWO, which is part of Coresight, the on-chip debug and trace solution used in the Cortex processor family and in the Stellaris family.

The user has full freedom to configure the types of packets sent over the SWO channel that should be displayed by IAR C-Spy debugger.

Additionally, debug log messages from a printf output can be also displayed by IAR C-Spy, without having to halt the execution.

IAR Embedded Workbench for ARM is developed to deliver high-performance compiled code.

The chip-specific code optimiser generates efficient and reliable flashable code for the Stellaris family of microcontrollers.

Recently added, multi-file compilation is a feature that allows the compiler to treat several files as one compilation unit, which means it can optimise over a larger scope of code.

IAR Powerpac is a family of real-time operating system, file system and USB and TCP/IP communication stacks.

It is integrated with IAR Embedded Workbench for ARM to ensure quick and easy project start-up and application development.

The 4th generation of Stellaris ARM Cortex-M3-based MCUs feature new combinations of connectivity, memory configurations, and advanced motion control.

The devices include six MCUs in Texas Instruments' LM3S9000 series (featuring an on-chip combination of 10/100 Ethernet MAC/PHY, USB On-The-Go, and Controller Area Network) and two MCUs each for the LM3S2000 CAN Series and LM3S5000 USB and CAN Series.

The new Stellaris family members further extend the ARM-based MCU product line by adding higher performance with speeds up to 100MHz and lower operating power with 130nm low-power technology.
