This development/breakout board (HCDVBD0040) is based around the ST Microelectronics S105K4 microcontroller. STM8 microcontrollers are an ultra low cost solution to embedded control. This development board provides convenient access to the devices I/O pins via standard 2.54mm pitch headers. Besides providing access to most of the microcontrollers I/O, there is additionally a microUSB connector for powering from a USB port, and a standard ST SWIM programming/emulation header that allows for programming or debugging using a compatible programmer such as our low cost ST-Link compatible USB programmer (HCDVBD0016). An on-board 3.3V regulator provides power to the board and is powered via the 5V USB or 5V header pins. The ST tool chain (STVD) is available as a free download from the ST website and is fully compatible with this board. There are also additional third party tools such as the Cosmos ANSI C compiler (8K limited) and the SDCC (Small Device C Compiler) which can be downloaded for free. Links to these tools are provided at the bottom of this post.
PLEASE NOTE: The USB connector is for powering the development board only. To program the board you will need a suitable programmer such as the STLink Link programmer and debugger: https://hobbycomponents.com/st-micro-el ... programmer

Development tools can be downloaded from the ST website here: http://www.st.com/web/en/catalog/tools/ ... 807/SS1747
A direct link to the STVD development environment is available for download here: http://www.st.com/web/catalog/tools/FM1 ... 7/PF210567
And the STVP programming software is available for download here: http://www.st.com/web/catalog/tools/FM1 ... 7/PF210568
A free 8K limited version of the Cosmos C compiler which is supported by the STVD development environment is available for download here: http://www.cosmic-software.com/eval_kit ... m_eval.exe
We recommend installing the Cosmos C compiler before installing the STVD development environment.
Alternatively SDCC (Small Device C Compiler) is a free compiler that is compatible with the STM8 microcontrollers and can be downloaded here: http://sdcc.sourceforge.net/
When trying to use the debug feature in the STVD development environment I get the following error: gdi-error : can't access configuration database
Go to C:\Program Files (x86)\STMicroelectronics\st_toolset\stvd\dao\ and install the ST Toolset.msi
If you are running 64 bit versions of Windows 8/10 and installing the toolset above did not resolve the problem open up a DOS command prompt in admin mode and issue the following two commands:
Regsvr32 /u "C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO350.DLL"
Regsvr32 "C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO350.DLL"
