BeRTOS: Free Embedded RTOS
- 1. Real Time Embedded OS Develer S.r.l.
- 2. Agenda “ Why Open Source software Discover BeRTOS Advantages for Business BeRTOS is a real-time system designed to build applications BeRTOS in short for embedded systems License BeRTOS in use 10 reasons to ... Questions?
- 4. Lockin avoidance No technological lock-in with respect to proprietary systems Many different companies can offer the same services on the market. The customer can change the source if the seller can't do or it's not interested in doing such modification. No mandatory binding with the supplier You can choose any supplier which satisfies your business demands. You can change business partner any time you want since the sources are shared. Open system An internal “expert” team can make any change to the source. You can easily train human resources thanks to the shared documentation. Quality and efficiency The developers commit themselves to code quality. Many developers improve the system thanks to free access to source code. It's often at the forefront of technology, it's well documented, stable and secure.
- 5. No license costs There are three main costs in a software project: - license purchasing, - program installation and customization, - internal costs due to resource organization. The cost for an open source based project is two thirds with respect to a project based on proprietary software. You don't pay the operating system, but only value added services such as human resources training or customized developments or ports on your custom boards.
- 6. Decrease maintenance costs It's built with modern technologies and paradigms Using standard technologies make it simpler to integrate the project with technologically different infrastructures. The community maintains it It's convenient to use open source software because maintenance is shared with the community, thus decreasing costs Integrated with your features Contributing your modifications means the community will maintain and keep up to date them with every new development for free.

Economical advantages Closed RTOS - License costs - Support costs Renewal - Maintenance contracts Contracts Fee - Annual cost increase Supplier Supplier License Support Maintenance - No license costs - No support cost - No maintenance cost BeRTOS - No cost increase No Fee Community Community License Support Maintenance
- 10. Supported platforms BeRTOS supports the most common microprocessor platforms (ARM and AVR). It's also possible to port it to any other platform. ARM7 AVR ATMega8 AT91SAM7S64 ATMega32 AT91SAM7S128 ATMega64 AT91SAM7S256 ATMega103 AT91SAM7X128 ATMega128 AT91SAM7X256 ATMega168 AT91SAM7X512 ATMega1281

- 12. Kernel Performance BeRTOS performances are remarkable, it can be compared with commercial versions of many RTOS (or more famous RTOS). A few KB on flash with all kernel modules active (semaphore, signals, message queues) Linear RAM occupation with the number of processes Minimum stack: 200 bytes on 32-bit ARM, 100 bytes on 8-bit AVR Context-switching speed: 2.2 us on ARM @ 48 MHz From 25% to 30% faster than competitors
- 13. BeRTOS vs FreeRTOS FreeRTOS BeRTOS Conclusions Maintainer 1 developer Community - Speed of Support/Bugfix/Needs Platforms - ARM7TDMI Yes Yes - BeRTOS allows quick ports to any - AVR Yes Yes custom platform - Other platforms Yes No Features - Graphical wizard No Yes - Quick installation and configuration on - Windows SDK No Yes Win, Mac and Linux systems - Debugging in IDE No Yes - Availability of development and - FAT filesystem No Yes debugging tools integrated with the - Log/Debug No Yes working environment - More features available Support - Community Yes Yes - Commercial Yes Yes - High quality technical support Licensing Modified GPL Modified GPL - Investments in software developments have competitive advantages without source code sharing
- 14. BeRTOS is different Code Beauty Every development on BeRTOS strictly follows the principles of code consistency and readability. The source code is completely commented to ease immediate understanding. Simplicity Every development on the BeRTOS system is implemented following the simplicity principle. This principle makes the system much more modular (it can work without kernel!) and more scalable in the requirements and performance. Reusability Applying reusability principles to BeRTOS code allowed to improve parameters such as occupied physical space and lower resource requirements for system usage. Security BeRTOS allows a completely static memory allocation, implicitly making more secure your developments and your embedded applications.
- 16. Fast Time to Market BeRTOS guarantees a fast time to market, thanks to a complete feature set and easy-to-use development tools that contribute to cut down project's realization time. (Many modules and drivers are already built in)
- 17. Shorter development time The reduced necessity to develop customized solutions can save you many development hours, thanks to many drivers and algorithms already included into the libraries. Drivers Algorithms ADC handling Checksum and Hash Flash memories Xmodem protocol E2PROM RLE compression Keyboard management Full Hash Table Graphical displays Command History Stepper and DC motors Command parser Triac for power control Lists and FIFOs PWN/NTC Exception handling Thermostat
- 18. Reduced startup costs Develer reduces start-up costs, offering BeRTOS as free operating system even for: - closed source projects; - commercial projects. ● The total cost of ownership (TCO) is reduced thanks to: - the development technical community - the modified GPL license @Image by Tab.itha: http://www.flickr.com/photos/tab_itha/
- 19. Focus on ideas With BeRTOS you can shift your economical focus from the tool (the required licenses) to the product (your application), as you don't need to buy a license @Image by Majed: http://www.flickr.com/photos/majedphoto/
- 21. Stable and mature system BeRTOS is constantly updated with new developments and patches which expand its features. The system is considered mature thanks to 8 years presence in Develer's embedded projects. Develer also provides ports and bugfix @Image by RyckyDavid: http://www.flickr.com/photos/cuppini/
- 22. Reusability = More opportunities Each component can be re-used in every other project, so you can quickly update or broaden your products by using existing code. This allows to: - release in short times a wider choice of embedded products; - be in the forefront to consolidate your position in the embedded software market. @Image by RyckyDavid: http://www.flickr.com/photos/cuppini/
- 25. Wizard: User's Needs “ With the new Wizard we want developers to focus on writing code for their project instead of configuring and getting the tools ready; we think we have made it possible to expand BeRTOS user base even more! Francesco Sacchi, Sviluppatore Simplify project start-up Auto-select modules based on dependencies Extended compatibility (Win, Mac, Linux) Integrated work environment (IDE, toolchain) BeRTOS optimized IDE
- 26. Multiplatform Wizard You're ready to create your application with just a few clicks! Create and modify quickly your project with a step-by-step graphical wizard: Select which BeRTOS version you want to use in your project; Choose Toolchain or microcontroller you want to use; Insert the modules needed by your application directly from the graphical interface; Generate a project ready for CodeLite o GNU Make! The Wizard is available on Windows, Linux, MacOS.
- 27. Build System User Settings BeRTOS 1.0.0 ... Makefile BeRTOS 2.0.0 ... CodeLite BeRTOS 2.1.0 WIZARD ...extensible with plugins ... The build system can exploit different BeRTOS versions to create, based on user's needs, a project compatible with GNU Make and CodeLite The system is easily customizable with plugins to be adapted to your IDE (Eclipse, Visual Studio etc.).
