qLibs

A collection of useful libraries written in C for embedded systems.

Remarks

qLibs is developed using a formal and rigorous process framed in compliance with the MISRA C 2012 and CERT coding standard guidelines and complemented with multiple static-analysis checks targeted to safe critical applications.
