I know the problem really was down to Mame (handling the rotation as an ananlog input IIRC) rather than hardware, so I am guessing Andy came up with a clever way of getting round this? |

There seems to be some confusion on this topic. Any rotary interface which does not properly take into account the minimum pulse width required by the application will have issues. This is separate from the MAME issue (early versions) which apparently relied on time based counters rolling over to indicate a new rotational index. I don't have the specific starting MAME rev in front of me, but later versions allowed for a perfect "1-click, 1 index" movement scheme. IIRC, this mode of operation could be selected by setting the "positional digital speed" to 0 and the "positional sensitivity" to 100%. Both under Analog Control Settings. This may or may not still be true under the latest versions using RAW input. Some of the earlier changes were lost in the transition. Hopefully this one wasn't as well. RandyT |
