the converter firmware is polling all the time and this makes the problem I am seeing at least way less likely.
With the MMBASIC firmware, on the other hand, it isn't possible to poll all the time, because MMBASIC wouldn't run anymore.
Do I understand it correct? I am really curious about your ideas for solving this.

Correct.

The new firmware allows for more than one new key-press in each USB report. This should mean that a key-press can't be missed.

Peter! Please see the attached video! I think we have a success. There are still problems but FOR ME they are not relevant in real life (at least for now, maybe I discover situation where it still might be problematic but see the video & definitely the new attached keyboard text file)


   

I think this gives you a good overview. Good work! If you want to try to fix the problems further I will test more. But this is a HUGE improvement.

Just to be clear, the double key only occurs in the editor?

No, as you can see in the video (timestamp: 00:00:26), the double key are also in the console.
So for now you've definitly fixed the missig keys. Only on some "lines" (the 4 row test) I see some double keys.

Here:

or

SDFG sdff   sdffg sdffg sdffg sdffg sdffg sdffg sdffg

and so on...

And I think this information may help to: It is impossible for me in some "4 key rows"
(no matter how fast I type) to produce double keys. some key-arrangements seem to be "rock solid" no matter how fast I type.

This is also in the console. And it is on all tested keyboards the same.

But as I said, this new fix is a HUGE improvement. No missing keys anymore.

Here is a RP2040 VGA USB version. In this I have reduced the scan rate from 20mSec to 10 mSec - please report

Pretty sure you are aware but:

I setup a HDMI USB system on a RP2350B and exactly the reported behavior @Amnesie also applies to this for me. I tried different keyboards.

Cleared the flash and let everything be default.
Of cause subjective impressions:
Much better. Seems that "qwer" is more easy to replicate over and over than "wert"

No missing keys, but still dublicate keys on the same spots.

Exactly, same here! There are certain groups which are rock solid, no matter how fast you type. This is one of them.

@ dddns could you please mention what keyboard you used? Model?

@ Peter

Even if you can't improve things much more, now it is at least usable! :) Seems that this problem is really hard to deal with because there are so many variables involved.

Have the duplicates gone?

Used a very old Dell SK-8135 with integrated hub and a noname US layout keyboard. Dell works better(subjective)

I don't understand how you have still got duplicates unless I posted the wrong binary as I've put a hard block into the code that stops the same character being registered with 50mSec.
Please try again with the attached. The version number will be V6.00.02p1 (patch 1)
If this doesn't work I think I'll shoot myself as it makes no sense.

Thank you, this is good to know. Because I didn't found a single keyboard (tried today another one from a good friend) that works. But with this fix, there is no dropped key anymore, which is a good sign - even if the dublicate problem can't be fixed.

 please not! I'll try it right now, give me a second... or two...

Aaaaaaand the answer is:

Uhm.. I was too euphoric / optimistic and didn't noticed until I saw the video I just recorded and tried it again..... you can see it in the video, too.


ZUIO "zuuio"


SDFG "sdffg" < still dublicates

I am so sorry :( hmpf....

But the WERT "werrt" problem is gone!
