16 \section overview Overview
18 BeRTOS is a real-time operating system designed for building applications
19 for embedded systems, like reference boards, test boards, or custom boards.
21 It has a modular structure: its components can be used in very different
22 environments, from 8-bit processor to Linux and Win32 hosted application
23 (for debug purpose), using a wide range of compilers.
25 \section history History and Motivation
27 BeRTOS was born as a extremely modular, highly optimized and fine-tuned
28 operating system for embedded programming.
29 As a result, each module has its own scope and can be used alone or in
30 cooperation with other modules.
31 It's even possible to use most of the drivers without activating the kernel module.
33 We have grown it following our guidelines: simplicity and beauty.
34 These guidelines made it possible to evolve it in a full-featured real
35 time operating system, with more modularity than many other embedded OSes,
36 without giving up reliability and performace.
38 To achieve the highest possible reusability, most BeRTOS components are
39 designed for fine-grained modularity and minimal external dependencies.
40 Most non-essential features can be configured out for applications with small
41 memory footprint requirements.
43 \section features Features
45 - multitasking kernel with IPC, semaphores, priority levels;
46 - a comprehensive set of generic drivers for a wide range of devices,
47 which can be easily customized to the actual hardware: timer, serial,
48 adc, ntc, pwm, stepper motors, dc motors, lcd, keyboards, buzzer, eeprom;
49 - full graphic subsystem for simple displays, with font support, bitmaps,
50 clipping, text formatting, interactive menus;
51 - simple console with command parser;
52 - readline-like support for command history;
53 - entropy generator and random numbers generator optimized for embedded
55 - checksumming and hashing functions (CRC, MD2);
56 - full hash-table implementation with double-hashing collision resolution;
57 - XMODEM protocol implementation;
58 - RLE compression algorithm;
60 \section structure Directory Structure
62 The modules are sorted in subdirectories by their category:
64 - app/ : demo applications;
65 - bertos/algo/ : algorithms;
66 - bertos/cfg/ : configuration stuff;
67 - bertos/drv/ : hardware drivers;
68 - bertos/dt/ : experimental object oriented gui toolkit;
69 - bertos/emul/ : Qt-based emulator framework for embedded applications;
70 - bertos/fonts/ : fonts;
71 - bertos/fs/ : file system related stuff;
72 - bertos/gfx/ : general purpose graphics routines;
73 - bertos/gui/ : widgets for simple displays;
74 - bertos/hw/ : hardware-specific declarations;
75 - bertos/icons/ : conversion tool from image TXT format to LCD bitmap;
76 - bertos/kern/ : multitasking kernel;
77 - bertos/mware/ : algorithms, other standalone code;
78 - bertos/struct/ : containers and other data structures;
79 - bertos/os/ : OS-abstraction layers for hosted environments;
80 - doc/ : documentation;
82 The top-level directory contains a few support headers that are meant to be
83 usable by any C/C++ embedded or hosted application.
