    RTuinOS

    The event based Real-Time Operating System (RTOS) for Arduino

    RTuinOS, the event based Real-Time Operating System (RTOS) for Arduino, is now hosted at SourceForge. In this revision, 1.0, the event concept has been generalized. Events can now be broadcasted events, semaphores or mutexes. This permits to implement all the usual inter-task communication patterns. Please refer to the user guide and the diverse code samples for details. The second technical change is a complete revision of the makefile. It has been improved in many aspects and it now supports three host operating systems; the RTuinOS samples (as well as your applications) can be built under Linux, Windows and Mac OS. RTuinOS 1.0 is distributed as setup (a ZIP archive), which contains all source files and the complete documentation, also with source files. Building the samples can be started immediately after unzipping and setting a single environment variable. Thank you for your kind interest in RTuinOS.

    Command-line tool to check ADFs (Amiga Disk Files) for errors and viruses. A binary is included for Windows users; Linux users are advised to compile the application themselves. Might also compile under plain DOS; but BE WARNED! When you scan files already renamed by the TOSEC standard, consider that file names may become insanely long in no time. --UPDATE OCTOBER 2014-- This project is currently suspended! I can't currently find the time to fix/update anything with this program and hence it must be considered 'on hold' at the moment. Sorry for the inconvenience.
