Hi,
ARAnyM's emulation of the IKBD does not support changing the y origin.
Bummer - any reason the origin was set to the top initially?
Isn't it sane to have the origin at top so the mouse increments are
logically in sync with video coordinates?
That may have been the reason, perhaps before the mouse driver was written to
the busmouse interface (not sure I have kernel sources dating that far back).
I guess we could reverse that (at least for ARAnyM).
I am against changing generic Atari related things just for ARAnyM. I
said earlier (about 12 hours before you posted this mail) that I would
fix anything in ARAnyM to make it more linux-m68k compatible.
Yep, I do recall that - my intention was to reverse the logic in order to give
Geert (and myself) something to test while you add the necessary bits to ARAnyM.
Such a hack would definitely be removed as soon as possible.
I am just not sure what's wrong here - does the linux-m68k indeed
switches the point of origin to bottom of screen and relies on that? Why
if you say that the old busmouse code used the "normal" top-screen
origin?
The original (and current) mouse driver explicitly set the top screen origin -
either at keyboard init (old) or at mouse device open (now). I do assume that is
not the default, power-up state of the hardware.
How would I go about figuring out the kernel runs on ARAnyM, Petr?
Using the NatFeats, of course. But see above - I am against such hacks
and I'll add the code for reversing Y-axis real quick if its really
necessary.
Point taken - I'll not complexify things further by attempting to detect ARAnyM
at runtime, then. I have a patch that should work on both current ARAnyM and
real hardware for Geert to test, and the hack is easily removed later on.
Thanks, Andreas. Seems I'll have to revive the old joystick code, then.
Michael, I don't think there is anybody out there using such hardware
joystick-mouse modification. But there is number of people using the
Eiffel PS/2 adapter so if supporting anything then I'd go for that.
How does that one work?
The only reason for reviving the joystick hack would have been to have a
'standard' way of passing a third mouse button. If the PS/2 adapter is that
standard way now, that's fine. I'll just need to know what interrupt/device this
is hooked up to, and what the data format is.
BTW, is it just my feeling that you kind of didn't take my mail
(Thursday 11:20) into account when replying to Andreas?
I was mainly looking for a quick way to accomodate current ARAnyM users like
Geert and me while a fix is being worked on. I did read your mail, and take
notice of your offer to incorporate a fix for ARAnyM, even though I did not
refer to your mail in my reply.
I'd still have to get a working X server before testing any of this, so it
probably won't matter either way.
Michael
