Unfortunately it only usable with a commercial license for quite some money, not up-to-date and MS Windows only too.

The good news is there is a free development environment for STM8 with all bells and whistles that even runs under Mac OS X: Eclipse.īefore we can start developing a firmware of the STM8 microcontroller we have to setup the hardware components of the development environment. Supply power to the STM8L-DISCOVERY board over USB.Prolific USB to Serial adapter with wiring Connect STM8 development board to Mac connection of the STM8L-DISCOVERY board from Olimex the USB-Serial-Cable-F adapter from Prolific the PL2303 USB-Serial adapter You need a development board for the microcontroller and connect it with a Mac. build up the connection via terminal in EclipseĮclipse can be configured to allow development of C++ firmware cod for the STM8 with editing, flashing and nnect the USB-Serial adapter cable with the Mac via USB port.alternative connect the USB-Serial adapter cable from Olimex via Serial connectors with the STM8L-DISCOVERY nnect the USB-Serial adapter cable from Prolific via Serial connectors with the STM8L-DISCOVERY board.power supply is handled via the Micro-USB connector of the board (the right USB port at the top image). ST-LINK/V2 is a programmer and debugger for STM8 and STM32īrew install autoconf automake pkg-config libusb libusb-compat stlink.maybe ‘brew doctor’ shows errors that have to be fixed before using HomeBrewīrew doctor 2.only needed to be installed if not installed yet.HomeBrew is used to comfortably install necessary tools over the command line.There are some steps that are critical to get Eclipse to work with the STM8 board. St-util does not recognize the DISCOVERY board and has problems using it.

A quick research shows that the tool only supports the SWD-mode for STM32-MCU’s. This mode is only usable with the tool stm8-flash that is not well-maintained.

This tool does not allow debugging at the moment. SDCC is a free cross-complier for multiple microcontrollers with great compatibility and able to generate excellent results.Ĭonclusion: Debugging of STM8 code is not usable under Linux or Mac OS X.Install stm8 cosmic tool chain install#.
