Bugzilla – Bug 7891
Front panel buttons sometimes do double push
Last modified: 2009-09-08 09:31:05 UTC
I find that sometimes pushing the knob once gets treated as if I'd pushed it twice. Entering a menu will actually enter it and select the first item etc.
Actually, I think all the front panel buttons sometimes do a double, or even triple push. I see this most on the knob and back buttons, but that's just because it's most noticeable with them.
I'm definitely seeing this too. Our debounce time needs to be increased, I think.
Felix thinks this might be fixed with the 7.0 debounce improvements. He says he will have a look at the buttons specifically, though.
Do you guys see this while in setup mode (i.e. not connected to SC) or only when connected to SC or in both situations?
Ok, I can see the issue too on latest PQP2 hardware, especially knob push is bad. The reason is that on PQP2 UI boards the debouncing caps on the knob switches have been removed because of other issues, which makes software debouncing necessary.
Added software debounce code for buttons (including knob push button) in re4249. Will be in fw 8.
