Fixed some erroneous module versions.
AMiRo-BLT and AMiRo-LLD updated as preparation for introduction of new AMiRo v1.2 modules.fixed typos.
Default shell configurations have been changed:Now the input line buffer can hold 128 characters (up from 64) and there can be up to 16 arguments per line (up from 4)
Changed the AMiRo-OS version back to 2.0.1 (from 2.1.0).This was done, because an increment in the minor version implies an API change, which is not present yet.
updated all aosconf.h files to AMiRo-OS 2.1
All preprocessor directives without arguments (e.g. #endif) are now followed by a comment, indicating where it belongs to (e.g. the preceding #if).
Enhanced and fixed several module specific files.
Changed all header guards so they will not use unserscores as pre- and postfix.
Enhanced the AMiRo-OS configuration: When AMIROOS_CFG_TESTS_ENABLE is set, the shell is enabled implicitely by AMiRo-OS.Before, this logic was handled in the aosconf.h file.
Enhanced the main thread IO event configuration.Therefore a new macro AMIROOS_CFG_MAIN_LOOP_IOEVENT_MASK has been introduced.
updated all file headers to 2019
Introduced a switch to completely disable SSSP (thanks to S. Welzel)
Doxygen file documentation and modules.
Introduced an mechanism to measure clock skew during operation phase, if AMIROOS_CFG_PROFILE is enabled (non-master modules only).The low-pass filtered skew is printed via the module:info shell command.
Introduced SSSP stage 3 of the startup phase (module stack initialization).
Several enhancements to memory structure, naming and code quality.AMiRo-OS is now prepared so the SSSP startup stage 3 (module stack initialization can be implemented).
prepended several macros with the 'AOS_' prefix
moved the /os/modles directory to /modules
