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:

RainbowBS Features

• Hardware Features
  • Any 8/16/32 bits CPU can use it.
  • One timer and very little flash and RAM needed.
• Software Features
  • Portable:RBS is written by C language,so it is portable on any C compiler compatible with the C99 standard.
  • Configurable:RBS has base components and optional advanced components listed below.

• OS Independence:RBS can run with or without OS support.It offers thread-safety feature for OS.
• PC Tools:RAutoConfig for generating configurable file by UI.

Requirements

1. Only CPU,timer,RAM and flash are necessary in the target system.
2. The C compiler compatible with the ISO/IEC 9899:1999 standard(C99).
