STMicroelectronics Releases Complete Software Library to Support STR7 ARM7TDMI-based Microcontrollers
Free downloadable ‘C’ library supports every embedded peripheral in each STR7 family
Geneva, December 2, 2005 – STMicroelectronics (NYSE: STM), a world leader in microcontrollers, has announced the final release of the comprehensive STR7 Software Library supporting its 32-bit microcontrollers based on the ARM7TDMI core: the STR71x series and the recently announced STR73x series. The ‘C’ language library – which can be downloaded free from the ST website at www.st.com/mcu – includes drivers for every embedded STR7 peripheral, and startup files for major third-party toolchains.
The STR7 library simplifies system design, enabling a faster time to market by allowing users to focus on their applications rather than on the internal architecture of the MCU. Developers making use of it benefit from a fast start and rapid progress, whatever the configuration of their MCU. Written throughout in standard ‘C’, it provides optimized code that follows standardized procedures and naming conventions to simplify debugging and aid future code maintenance.
The software library can be used with any toolchain or ‘C’ compiler that supports the ARM7 architecture. Specific support is included for the ARM, Raisonnance and IAR toolchains in the form of dedicated startup files. Additional information is provided to facilitate use with toolsets that are not specifically supported; the choice of development toolchain remains with the user. Extensive training material and documentation are available to guide developers in using the library efficiently.
One standard library is available for each STR7 family, plus a separate USB-IF (USB Implementers Forum) certified library that supports STR7 devices with embedded USB 2.0 Full-Speed. The standard library includes drivers for each peripheral, including the general purpose functions such as Timers, A/D Converters and I/O, as well as for more complex peripherals such as CAN (for automotive and industrial applications).
Further information and access to the free software library, documentation, other software tools and the discussion forum is at www.st.com/mcu.
