About
I'm Tilen Majerle, an embedded developer at heart who now leads product marketing for STM32 Mainstream microcontrollers at STMicroelectronics.
Over the years, I have written many small, dependency-free C libraries for microcontrollers: parsers, buffers, memory managers and protocol stacks that are easy to use and fit on devices with only a few kilobytes of RAM. Together, my open-source projects have more than 10,000 stars on GitHub.
Several of these open-source projects, along with others I've contributed to, are listed below.

Questions about a library are best asked as a GitHub issue on its repository, so others can find the answer too.
