Download COSMIC STM8 32K C Compiler 4.3.13 from our website for free. This free software is an intellectual property of COSMIC Software. This PC software can be installed on 32-bit versions of Windows XP/Vista/7/8/10. Cosmic stm8 Cross Development Tools Cosmic's toolchain for the stm8 family is part of a complete and uniform product line incorporating over 20 years of innovative design and development. All Cosmic products include one year of technical support and updates. The Cosmic stm8 compiler follows ANSI and ISO rules and conventions.

Cosmic is creating CXSTM8, a professional C compiler for STM8 (COS-C-COMPILER), that comes for free whatever the STM8 silicon. The package includes: an integrated development environment with optimizing ANSI-C cross compiler, macro assembler, linker, libraries, hex file generator, object format converters, debugging support utilities, run-time library source code, and a multi-pass compiler command driver. The compiler also supports non-intrusive C source-level debugging with Cosmic line of ZAP debuggers. CXSTM8 can be fully integrated in ST Visual Develop IDE and debugger. This product is supplied by a third party not affiliated to ST. For the latest information on the specification refer to the third party's website Key Features • ANSI and ISO C compiler:the Cosmic STM8 compiler follows ANSI and ISO rules and conventions. All code and libraries are optimized specifically for the STM8 processor core.

All STM8 derivatives and sub-families are supported. Complete neo geo rom set. • Reentrant and recursive:with all programming models all code is fully reentrant and recursive using standard ANSI stack frame conventions.

• Memory models:CXSTM8 supports four programming model options to fine-tune code optimizations to an application and memory requirements. • C support for Zero Page:compiler source extensions provide efficient use of the STM8 short-addressing mode and single-byte pointers.

• BIT variables:in addition to Standard ANSI C bit fields, CXSTM8 supports single-bit variables using the _Bool keyword providing an easy and efficient bit-packing mechanism for true/false flags. • In-line assembly:the compiler provides three convenient methods for adding assembly code inside a C program. Includes an argument passing mechanism. • Absolute listings:optionally produce relocatable and/or absolute C interspersed with the corresponding assembly listings. • IEEE-754 floating-point:supports IEEE single floating-point formats with full ANSI libraries (source code included).

• Movable code:movable code feature is designed to make RAM-based code-like bootloaders and programmers easy to create and maintain. The linker automatically creates a segment in ROM to store movable code. At run time, the supplied library function is used to relocate and copy the movable code into RAM for execution. • Checksum:easy-to-use checksum facility and library (source included) allow users to quickly implement an efficient checksum on any or all sections. Checksum calculation and insertion is transparently managed by the linker.

• Mixed C and assembly:Cosmic tools support mixed C and assembly applications, including assembler support for C #defines and #includes. In this way C and assembly language modules may share common constants and macros. • Host independent formats:the Cosmic relocatable and absolute object formats are host independent. This allows users on PC, SUN and HP workstations to share objects for linking and debugging. • IEEE-695 and ELF/DWARF debug support:the Cosmic compiler suite supports the IEEE and ELF DWARF standard debug formats used by many popular emulators and logic analyzers.

• In-Circuit emulator compatibility:CXSTM8 is compatible with all existing emulators. • Flexible compiler interface:Cosmic compilers are designed to be powerful and flexible so they can be used with virtually any environment. Cosmic provides a development environment (IDEA) but the user can select his favorite editor, make utility and/or source code control system.
