A class in level II is classes described by a number between 512-65535. However classes between 512-1023 is a mirror of the level I classes. This space is called level I classes over level ii and is described here
Instead of writing numbere a class can be described as CLASS2.level1.XXXX indicate a specific (XXXX in this case) Level II class. Also the form CLASS2.level1.XXXX=yy can be seen where yy is the numerical form.
This type of classes have the same data content as level I classes except that the data is shifted 16-bytes. The first 16 bytes are instead used for the destination GUID. This is typically the GUID for a specific node or a GUID for an interface on a node or at the VSCP Daemon.
Class definitions can be found in the header file vscp_class.h which is located located in the src/vscp/common folder of the VSCP project repository. In the same folder the file vscp_type.h can be found which contains defines for all types. Note that both of these files is auto generated.
VSCP event documentation and support files are auto generated. The full documentation and source for the scripts that generate misc. files is here if you are interested.
Current files is available here https://www.vscp.org/events/ The docs sub-folder here contains event documentation in markdown and also a zip and a tar of all content. This information is used to generate the VSCP specification document.
All files generated contains version information which is the date and time when the docs was generated. This information is embedded in the generated files (if possible) and is also available in JSON form here (version.json) and in JSONP form here (version.jsonp). In automated processes compare the on-site version information in one of there file with the downloaded version and download a new version if a newer one is available.
C header files are are here for event classes (vscp_class.h) and here for event types (vscp_type.h). The files are automatically included in the vscp and the vscp-firmware packages.
Python VSCP event include files are here for VSCP classes (vscp_class.py) and here for vscp types (vscp_type.py). The files are automatically included in the pyvscp package.
The vscp_hashclass.h and vscp_hashtype.h files are headers for the vscp helper class.
For JavaScript VSCP events are available in JSON format (vscp_events.json) and in JSONP format (vscp_events.jsonp). Furthermore vscp_class.js and vscp_type.js holds VSCP class and VSCP type information suitable for JavaScript.
XML format is available here (vscp_events.xml).
SQL format is available here (vscp_events.sql).
