TOKN KB16 (Tiger-Heli's Testing Complete)
Tiger-Heli:
This is in relation to my comments in this message (currently locked) In this reply, I implied that an 8x2 matrix encoder could avoid ghosting without the use of diodes.
Mainly I am posting this as I hate inaccurate comments on the board, and my comments in that particular message confused RandyT (among others), which was an accomplishment in itself. I re-thought my position and now want to re-state it as follows:
My original theory was incorrect, I don
nostrebor:
I had considered trying one out in the past. Even bid on several in an attempt to pick one up at a reasonable comparative price point. I would have gone so far as to consider sending one I purchased to someone to test out, if it would have cleared the water on the matter of the matrix. But after the reactions here of mattp, I have decided not to support his product. Trust and respect must be earned, and EBAY feedback alone will not get there in my book.
Randy or Andy will get my $$$ at this point.
Tiger-Heli:
A matrix-based encoder, in and of itself, isn't a problem. (It probably won't be as fast as a direct input encoder, but we've been down that road before).
The problem is Mattp initially said it did not use a matrix or diodes, then said it did, but didn't say that it used diodes, so now nobody knows what it really is or isn't (at least I don't).
<Edit> we now know it is an 8x2 encoder with no diodes and with ghosting
Chris:
Doesn't KevSteele have one of these in his possession? If so, it should be easy to wire up all the inputs, press them all, release them all and see the results and put this to bed once and for all, shouldn't it?

Hi.
just to shove my two peneth in.
A major problem i have with the thing is the fact that it is advertised as hot swapable.
If Mattp can show me the part of the IEEE defacto standard that says a PS/2 device is hot swappable i will gladly and publicly retract this gripe.
I have no vested interest in any of his competetors products before i am accused of such. I merely think that this is at best, poor research or at worst, a blatant attempt to deceive people who may be less knowledgeable. i am however sure it is the former. :)
