hello
I followed the discussion about this "generic" protocol. It seems there is a lot of talk about non-generic choices (cf. pressure). Does the packet need to have a fixed length ? I don't think so. We could have a config struct that can describe a pointing device capabilities. For example, a pressurized-pen tablet (!) :
The config : name,min value,max value
{ {"x",0,6000}, {"y",0,4000}, {"pressure",0,15} }
When the application (which has to be enhanced a bit) start up, it just look if there is a "pressure" field in the config. If yes, then the *application* will know that the 3rd field is the pressure field, and the the value can be between 0 and 15.
"x" and "y" are nearly always present
Please comment
