Atomthreads now contains support for Raisonance's STM8 compiler RCSTM8. We now support all three available STM8 compilers (Cosmic, IAR and Raisonance) so you can choose to use Atomthreads for a project safe in the knowledge that switching compilers will be pain-free.
The STM8 port contains largely common code with only a small number of conditionally-compiled sections to handle the differences between the compilers. For example functions… Continue reading

This week Atomthreads became the first RTOS to support Embedded Workbench (EWSTM8), the STM8 compiler launched by IAR last month. EWSTM8 provides a full professional-grade development and debug environment with support for hardware debuggers including the low cost STM8S Discovery platform. IAR offer a 30-day evaluation of the full version, as well as a time-unlimited 8KB "Kickstart" edition (with a few non-core… Continue reading

I have just completed a port of the Atomthreads RTOS to the STM8 microcontroller. Anyone interested in running an RTOS on the STM8 can download the source code from http://atomthreads.com.
This has to be one of the easiest architectures I've ever ported an RTOS to. There are only six CPU registers and only three of these are general purpose registers for compiler use. Continue reading

Last week I released Atomthreads, a free RTOS for embedded systems. This project grew from a task scheduler I created some time ago and subsequently extended with semaphore, mutex, queue and timer modules. The result was a lightweight and portable set of kernel sources which can be dropped in to any embedded systems project to add a thread scheduler. It has been useful to me so I decided to open source it in case it proves useful to anyone else. Continue reading
