PygmyOS is an operating system originally intended for the MSP430 series of microcontrollers. It has since outgrown the MSP430 and is now primarily intended for ARM, specifically the STM32 and other similar CortexM3 core MCUs. PygmyOS was built from the ground up to be quick and flexible with code that is both user and MCU friendly.

Current status

PygmyOS is still a young project. We will have a full official release sometime soon. Until then, you can download the most current stable code base here and browse the source repositories here.
