Nano OS (or nOS) is being developed keeping the requirement of small micros in mind.

A typical microcontroller programming involves more time dealing with the peripherals and less time dealing with multitasking. Thats why the nOS covers the peripherals programming more seriously.

Current version of nOS will cover the following micros and functions.

1. 8051
2. ATMEGA series
3. PIC family of microcontrollers

The Latest version is available in downloads section.
