All trial versions contain a complete ready to go start project, the users manual and embOSView tool which can also be downloaded separately from our download page. Of course there are some limitations for the trial version: Using the trial version in a product is not allowed. The trial version of the embOS libraries run without a time limit with a maximum of three tasks. If your application creates more than three tasks, embOS stops after a time limit of 15 minutes. Customer support is not included. Check here for the available embOS trial versions and documentation.

Check out what it means! Comparatively, a paper from scholars at the University of Suceava in Romania estimates that on the exact same MCU, alternatives can take as much as 1, cycles while the fastest ones in their benchmarks dropped to cycles at best. Unlike other competing solutions, embOS obtained these certifications after minimal rewrites, if any, because it had robustness and reliability in mind from the start thanks to its very modular approach.

The kernel has two parts: a generic component and a hardware-dependent facet. The hardware-dependent part pushes these optimizations further by taking advantage of certain aspects of a particular architecture.

One of the reasons we work closely with SEGGER is that their solutions for our components are free to use for evaluation and educational purposes without any technical limitations.

Their presence in the ST Partner Program thus shines a light on their selector page to ensure our community enjoys the fruits of our collaborations with frictionless access to reliable and powerful software.

Cortex-M architectures include a bit system timer SysTick in the form a counter that decrements and throws an interrupt at every tick. Unfortunately, this system is far from optimal when trying to put the microcontroller in a deep sleep because of its numerous interrupts.

The application will look at the duration of the low-power mode and only throw an interrupt when TIM2 reaches its maximum count time instead of sending one at every single tick. If developers use SysTick, they get interrupts, which significantly limits the power savings possible during this deep sleep mode. It also explains why an increasing number of companies are moving away from Linux and adopting a real-time operating system for their computationally demanding application.
