I know how to do assembly in the calculator with out a computer or link. You can also download some files without the link this way as well! it's soo cool!!!

can you teach me how?
i've really wanted to learn

can you teach me how to do it too ive also wanted to no

whenever i try to display text it comes out funny, usually offset

plz help!!!

I'm willing to help as much as I can, but I need a little more information.

What calculator is this for?
What kind of text display routines are you calling?
How is the text offset?

Could you post some of the code and a detailed description of the problem?

its okay i figured it out

i entered the wrong .org thing

thx anyway

Has anyone even attempted to make an OS for the 83+ made to completely replace the TIOS? Some thing along the lines of pedrom for the 89. this may be a stupid question

I made one for school. But from the programmers point of view its really not that interesting, its just designed to do basic calculations and stuff. The OS for example is closed. And the interface is very, very basic.

I'm trying that right now (I haven't written one line yet, I'm still brainstorming, finding out what might be useful and trying to get more information on the hardware interfaces), but I really need to find an emulated version of the 83+ that ACTUALLY WORKS...

The TI Flash Debugger application, for instance, crashes when you try to write data to a FlashROM page directly (by ldir, haven't tried ld yet).

Completely replacing the OS will be risky as replacing the code in ROM may be unreversable as the calculator may not function at all after this is done. Also the ROM calls in the TIOS are needed for the programs that run, so you need to make all new applications or copy the ROM code. You would be better off creating an application that seems to replace the TIOS by starting up whenever the TI is turned on. The TIOS could then be restored probably by resetting the calculator. After tis, the application needs to be reinstalled. Think of Windows 3.1 running over DOS.

I like to change my cutom menu to list all my games and util/tool programs, and all the ee units I use...

but it is a PAIN to have to re-type it everytime I want to change it! Somebody needs to make a program that grabs the command to put the custom menu how it already is so that you can change something small!

What do you mean? Do you mean a function that returns the current custom menu?

i'm trying a new way to do _getkey i saw in asmguru but it doesnt seem to work (i made the prog myself)

here is the source:
#include ti83plus.inc

.org 9D93h
.db $BB,$6D

bcall(_clrlcdfull)
bcall(_runindicoff)
ld b,47
ld c,32
ld d,1
bcall(_ipoint)
getkey:
ld d,0
ld a,0FFh
out (1),a
ld a,0FEh
in a,(1)
out (1),a
cp kleft
jp z,left
cp kright
jp z,right
cp kup
jp z,up
cp kdown
jp z,down
ld a,0FFh
out (1),a
ld a,0FDh
in a,(1)
out (1),a
cp kclear
jp quit
jp getkey
left:
bcall(_ipoint)
ld d,1
dec b
bcall(_ipoint)
right:
bcall(_ipoint)
ld d,1
inc b
bcall(_ipoint)
up:
bcall(_ipoint)
ld d,1
inc c
bcall(_ipoint)
down:
bcall(_ipoint)
ld d,1
dec c
bcall(_ipoint)
quit:
ret
.end
END

can someone help me?

thx

for one, i think it needs to originate from 9D95h, not 9D93h. i can't help you too much though, as i haven't had the time to read any ASM tutorials.

can someone show me how to scan specific areas of the calc for keypresses for the 83+

i would really appreciate it

Find yourself tutorials on "direct input".

On the TI86 it is a port for direct reading from the keyboard and a ROM-call for the TIOS's read function (similar to getkey). Go to the programming section and find an ASM tutorial for your calculator.

Hello, I am working on a BASIC format shell for the TI-82, since I do not know assembly format, I prefer to use basic. LightsOn is a Windows based shell, only with a different look (did not want to copy Windows). I have been programming it for a month now, and if anyone would like to help me on it, I would be glad. If you have any private comments, please contact me at twokool4me35@msn.com. I am 14 and have been programming for little over a year.

I have this idea about an APP for TI-83+ that add more sign (such as @, $ % ^ &, ect.) to the TI-83+ using keyhook. That it'll help a basic programer while trying to write his email address but unable to make the "@" sign . Since I'm just a rookie and have no idea how to program it. Can you create such APP? You can email other programmer to help you on this.

You could use a font editor. I don't know where you would get one, though.

omnicalc has a font editor
