The newlib-nano is an open source C library (libc) targeting embedded microcontrollers (MCU). Implementation focus is on code and data size reduction through optimization and removal of non-MCU features.
It was originally developed for ARM Cortex-M based MCUs as a part of the GNU Tools for ARM Embedded Processors see this link for more details.
newlib-nano is a derivative of the well known newlib C library for embedded systems.
This project goal is to enhance newlib-nano with additional features and extend support to additional MCU families.
