[TI-ASM] Handling Keypresses for ALL z80 calcs

Throwaway Identity · Post by **Throwaway Identity** » Sat 14 May, 2005 10:35 pm

I'm attempting to compile the same source code for all z80 calcs (73, 82, 83, 83+). Yes I know about Dwedit.inc No, I don't want it. I've been using the Unification FAQ as a guide.
I know how to handle TI-83(+) keypresses... use ifdef and direct input. But 73 and 82 are a mystery to me- especially the 82! Here are my questions (btw I am trying to avoid ifdef's in the source, only in the include...)

TI-73 (Mallard, duh):
- Is direct input even an option here?
- If I can use direct input, does anybody know where I can get a list of the correspondin g hex codes, keygroups, ect?
- is there an equivelent of getcsc, and how fast is it?

TI-82 (CrASH):
- Is direct input even an option here?
- If I can use direct input, does anybody know where I can get a list of the correspondin g hex codes, keygroups, ect?
- What is this g_kHAND thing for keypresses? As much info as possible here.
- Is there an equivelent of getcsc, and is it fast?

ALL

- What in general is the best way to handle keypresses over all z80 calcs?

thanks in advance, and please see-also my ti-82 vputs question

The 73's hardware should be almost, if not, exactly the same as the 83+'s. You should be able to do direct input in the exact same way as the 83+. The key codes should be the same as the keys in the same location on the 83+. As for the 82, I'd imagine it'd be similar.

fixed typo

ALL the TI-8x's have identical direct input. Even the TI-89, despite a different processor.
The only differences are what keys exist at each location.

so what you are saying is that the key group $BF on the TI-83+ is still $BF on the TI-82, AND it is the same keys? That would be

, and make me feel

...

EDIT: One last thing, since VTI doesn't emulate 73, are the keys the exact same as the 83+ (what I mean is the NAMES of the keys, not the hex). Seems they would be, since apps, ect...

Get the Flash Debugger, it emulates the 73.

TI-82-specific tutorial here : http://karma.ticalc.org
key reading is explained there

and the best solution to interact w/ the keyboard is direct input :)

and about compiling includes and stuff, w/o Dwedit's include, you can have a look at my sources (with #define's though)

jeez, everyone seems to want to help!

! That's great, though. No way I could have done this without UnitedTI.org and this foru,

... Does flash debugger graphically show the calc, btw?

@pacha: yes, everyone and their mothers uncle seems to be showing me that link. I found it bymyself on ticalc looking for 82 references but didn't look much into it. Seems I should again.

again, thanks for all the help.

Yes it displays it graphically, just like VTI. It also does the 83+ and SE ... and it supports APPs and such. But be warned, it is buggy.

thanks, i just need a picture of a ti-73. I've never seen one b4. Do I need a rom image or something? I guess I've just been to spoiled with vti

and pinder ti

EDIT:

OMG! I just saw what a TI-73 looks like! t3h ugliness! the... OMG!
it looks a lot different from what I thought it would. but on to a strictly professional outlook.

The keys have been switcherood. So the hex and the corresponding key will be the same, but that keys name will not. Since layout is the same, perhaps I should just say 'Pretend it's a TI-83 and deal with it!'... "

does anybody have any idea about what to do about this?

The flash debugger supplies its own copy of the OS. (read: no ROM needed)

Heathen! I'd choose a 73 over the look of an 84+ any day!

do you OWN a 73? see the 'announce your projects' section (betatesters)

Nope, if I did I would've posted. But I did start out programming in TI-basic with a 73, and miss it. I even tried to load a TI-73 OS onto my 84+.

Of course that won't work! The 84+'s bootloader jumps to a different location after it loads the OS. If you try hard enough, you MIGHT be able to get it onto an 83+.
