What is RainbowBS

RainbowBS(RBS) is an open-source base library developed for embedded systems especially with limit resources.

RBS is written by C language in compliance with the ISO/IEC 9899:1999 standard and it is set-up to be highly portable.Therefore it is independent of hardware architecture and can be incorporated into low cost micro-controllers like 8051,AVR,PIC,ARM and etc...,just with small porting code.

This document shows you how to configure and use RBS.

Following diagram shows the RBS position in the entire software architecture:
