SDCC still falls short in floating-point performance. The default path address is C:Program Files (x86)COSMICFSECompilersCXSTM8 and should also be the path on your machine if it was not changed during installation. However, stcgal still needs non-free binary blobs for use with some devices and the ST-LINK has non-free firmware. We will use the Cosmic C compiler so you should set the toolchain as STM8 Cosmic and the toolchain root should be the path where your Cosmic compiler was installed. IDEs complete the development environment.
OpenOCD and GDB allow on-target debugging via the ST-LINK.
Stm8 free c compiler serial#
Programs can be flashed by stcgal (via a serial link on STM8 devices that have a bootloader) and stm8flash (via the SWIM interface of ST-LINK hardware). SDCC quickly surpassed the non-free compiler in standard compliance and OS support and generates substantially faster integer code. New tree-decomposition-based algorithms from recent compiler research have been implemented in SDCC, including a new register allocator particularly suited to irregular architectures with few registers. The most important part is the Small Device C Compiler (SDCC). In recent years free tools for it started to appear and now form a free toolchain that surpassed preexisting non-free ones. For quite a while there were no free tools, and the irregular architecture makes it hard to support in GCC or LLVM. The STM8 is a popular 8-bit architecture by ST Microelectronics commonly used in household electronics, automotive application and industrial controls.
