Description Dan Evans 2009-06-12 16:17:54 UTC

That is, I push the knob once but it registers 2 pushes.

Firmware 6080.

Comment 1 Blackketter Dean 2009-06-15 22:00:12 UTC

This is easy to see in the factory test screen. I think it's just a longer debounce time is needed.

Comment 2 Wadzinski Tom 2009-06-16 12:19:11 UTC

I'm unable to replicate this. Do you still see double presses?

At r6086, yes.

Comment 5 Richard Titmuss 2009-06-22 13:28:59 UTC

Button debouncing added in fab4 r6204.

I don't see this often, so please reopen the bug asap if you see bouncing still after upgrading to this version. Thanks.

Comment 7 James Richardson 2009-07-06 15:14:26 UTC

with r6372 I'm either seeing this bug, or another bug.  When going to App Guide, attempting to enable an feature with the knob, it will 'double' tap some times.

OR, not select at all.

Using the 'play' or the IR it selects right away

Comment 8 Richard Titmuss 2009-07-06 15:19:34 UTC

caleb, can you take a look at james unit and measure the bounce. cheers.

Comment 9 Caleb Crome 2009-07-06 16:25:20 UTC

I took a look at James' unit, and unfortunately I soldered a wire to it to make monitoring easy.  The problem disappeared.

I suspect this is due to a cold solder joint in the knob soldering.

We need another bouncy unit to verify the problem.

This bug has been identified as one that may not be required for MPQ since it now seems clear that MPQ and MP firmwares will be different.  Please comment if you disagree with this assessment.  Thanks!

Huh, I still see it on r6372.  Its hard to make happen bur it does happn sometimes.   Richard, what rev did you make the 100 ms change in?

Comment 13 Caleb Crome 2009-07-09 11:07:15 UTC

Once again, can't reproduce here.  Pretty sure it's a soldering issue, so will postpone to MP.

Comment 14 Caleb Crome 2009-07-16 11:15:12 UTC

Should be resolved with 12844.
