With the semf middleware library lots of helpful modules and interfaces stand ready for your embedded projects. Because of its platform independency, the source code can easily be reused and projects can be ported so to say effortlessly.

Features

Real C++ object orientation with open class architecture
Reusable source code
Platform independence
Easily testable source code
Less debugging
Solves the big and small hurdles in everyday developer work

Value proposition

Saving of valuable developer time and cost reduction
Significant reduction in time to market
Fewer complaints and therefore happier customers
Happier, more productive developers who enjoy coding more
