The Raisonance technology at the heart of our STM8/ST7 C compiler ensures a thoroughly refined, tested tool that delivers the best results for your STM8 or ST7 applications, exceptional ease-of-use across a complete toolchain and efficient, direct support from Raisonance.

The STM8/ST7 C compiler offers a complete range of features tailored to these ST architectures for optimal compiler results.

Features include:

• Full range of compiler code size optimizations organized in 4 structured-levels for easy implementation

• Automatic startup file inclusion and no required link scripts

• Automatic interrupt vector and handling of absolutes

• Reentrant and recursive code

• Auto putchar and getchar integration

• Libraries coded in Assembler language

• Printf library adapted for needed functionality with smallest possible footprint

• Advanced data overlaying technology

Toolset integration and careful compiler testing ensure compiler ease-of-use and reliability.  Seamless integration in Ride facilitates access to the compiler as you write and debug application code. Use of Raisonance CodeCompressor technology can further improve code size with post-link code optimization across the entire application. Point-by-point compiler performance testing with STMicroelectronics, a combination of regularly updated test suites for anti-regression and ANSI conformity, and regular benchmarking ensure the quality and evolution of the Raisonance STM8/ST7 C compiler.

Free demonstration versions of Raisonance software toolkits (RKits) including an STM8/ST7 kit outputting up to 16 K bytes let you try compilers and the complete tool environment with minimum risk and no obligations.
