Support for Rotary Encoder Dial sensitivity levels, issue #965 (#1057)
* Support for 3 levels of rotary encoder sensitivity #965
Backend support; UI will still need to call set function to configure.
* Support for 3 levels of rotary encoder sensitivity #965
Backend support only. UI will still need to be changed to call the set_sensitivity() function to configure.
* Removed trailing space
* Deleted blank lines to see if format checker will be happier
* Simpler support for multiple levels of encoder sensitivity, for issue #965
Removed the convoluted code :-) and instead just using a 2-dimensional array to choose which transition map to use. For now I only have 2 (vs 3) levels enabled as well, to save code space and because high-sensitivity is very touchy.
