Post your ideas for new miscellaneous programs here, or build on ideas posted by other visitors.

I was just wondering if anyone was working on a wireless netwrok or something to that nature. so that you could transfer programs and such wirelessly to another person. it would have to be somekind of adapter or something that you would have to buy and plug into the port at the bottom of the cacl. if anyone or you know of anyone who is working on that please email me icewing24@msn.com

thanks

It already exists... look up RadioLinc (yes, with a C) on Google.

i tried that and its down
if anyone has anything from there send them to me at
Destroyer_XO@hotmail.com
i would do anything for it

i have make one with two modules with a bitrate of 900Kb/s and it supports almost 4294967296 calculatores so isn't big deal i have inplanted him on my calc because it is two small and feat in there...

radiolinc has been discontinued.

Someone needs to make USB8X for the 89T and develop support for USB Wi-Fi adapters.

That is too bad, because I would have bought one, especially for a chat program!

Well, this is my idea: TCP/IP (internet communication) on calcs. Basically, i want to internet enable the new Ti-84+ calcs, but to make this happen i thought that i would try to get it to work on the Ti-83+ first. I have no idea how PPP and stuff like that are handled, but since it's going to be needed for people to connect with a modem (not the only possibility i have in mind), i will have to learn how the protocols work. So right now i'm asking everybody that knows the workings of TCP/IP and PPP for their help on this. I program in 83+ ASM, and i think that i have the experience needed to make the calc do this, but as i said before i need help with how the protocols work, so if anybody know ANYTHING about this or have ideas, suggestion or questions, please reply here or email me at m@danscape.dk.

Also, if anybody is interested in joining me in this project, let me know.

cheers!

(the only real concern i have about this is the 83+ linkports sad disability... i cannot send and transmit at the same time... i don't know if TCP/IP is possible to do with that kind of link...(?) but of course, this problem will be solved by the 84+'s USB port.)

I know this probably isn't in the right place but, could someone please send me a "rom image" for a ti-83+ so that I can run virtual ti? I can't use mine because I only have the usb cable that comes with ti connect. I really need to be able to use virtual ti so i can make screenshots for my mario worlds and to test asm programs i am going to make, so if someone could please send me that or tell me how else i could get vti to work, it would be greatly appreciated.

I cant even get my calc to do a rom dump....

heres an idea:
I have WIFI in my house and so my comp is connected to a wireless USB adapter. Since it uses USB, it might be able to work with a TI-84+ if someone oculd port a driver.
Alternatively, and with a lot more effort, someone could design a network adapter just for calcs. when this is available i would like to know about it and buy it, but i lack the programming skills to do it myself, as i only know BASIC. (i only got my TI three days ago and its not that easy to learn ASM in three days)

You are learning how to program in asm on a ti-84 where do you find the info i wish to know how to program asm

You can learn to program asm for a ti84 by going 2 programming, tutorials, ti83+ (same basic tags as ti84), and clicking one of those tutorials. I suggest jeff chaiwhich; comes w/ everything u need!

did you get any reply on your question. i have the same proble .i also have a usb cable i cant get it working. listen if u got the rom image for the ti-83+ then can u please send it to me

You could try uIP (Web Page). It's a full-featured TCP/IP stack designed for 8- and 16-bit microcontrollers (as found in TI graphing calcs), and it's pretty small too; with all features included it's about 6KB of code size and a couple KB of RAM for data. Many features can be turned off to make it much smaller than that.

It's licensed under a BSD-style license (open source), so it's good to go!

The sticking point with it, though, is that it's written in C, and I know of only one decent free software C compiler for the Z80 (sdcc) but I haven't figured out how to make it not use the IY register as a scratch register. One way around this is to compile it with sdcc and fix it by hand.

I found another, more promising C compiler: z88dk. I haven't played with it very much, but it claims to support several Z80-based TI calculators. If I had the time and if I cared enough to make TCP/IP for calcs, I would.

I was thinking about designing some hardware for the same purpose...I haven't completely figured out PPP and DHCP, but I've got plenty of docs on all the protocols if you want them.

i know about protocols and as i said for radiolonk ihave created a way for supporting almost 4294967296 calculatores i'm portuguese and i dont know all about english but if you are interested how i have corrected the problem without hubs and all the other stuff contact me shadel540@hotmail.com i have tested it for 32 calculatores and it work "and it was on a math test"

I think that a feasible solution is to use a device to listen on a modem line while a PPP connection is being negotiated, if we are even going for PPP/MSCHAP/SLIP/CSLIP on a modem.

I NEED ADVICE FROM ASM PROGRAMMERS:

I need to know how to use/make/manage arrays in asm.
I want to know how you asm programmers handle arrays;
resizing, moving, etc...
And temporary (non-global) vars; is the stack okay to
use?

Is there a way to use the OS's file system or whatever
to manage asm created vars for me? This involves stuff
like multi-dimensional arrays, passed & returned
values, OOP Objects containing OOP objects (All this IS
possible; no need to know how I am doing it)..

What do you do for this kind of stuff? Is there a way
to create temporary files / vars?

It is simple! all a calculator is is a bunch of #s so if you want to create arrays all you have to do is add some bytes in your program to access that array.
EG
1-D array(3 item list): .db $F3,$A9,$1F
2-D array(3X2 matrix)(label 1): .db $F3,$A9,$F9
(label 2): .db $C6,$A9,$3D
All you do is store to the correct label and voila!!
If you are still confused EMAIL me.

I assume by temporary (non-global) vars you mean small amounts of data a function uses while it's running. If this assumption is incorrect, please disregard this comment and rephrase your question more clearly.

C compilers most typically emit code which stores local variables (vars which are in scope to only one function) on the stack. On the Z80, there are two standard ways I know to access variables on the stack.

The first method (as used by SmallC) is to use HL. At the start of the stack frame, decrease SP to allocate space for local vars. To access a var, LD HL with the variable's offset from the start of the stack frame, then ADD HL,SP. This will put the var's address in HL. You can do anything with the variable using its address at this point.

The other method is to use IX as the stack frame register. PUSH IX, LD IX with the stack pointer, then decrease SP to allocate space for vars. Then to access a local var, just use (IX+n), where n is the offset from the top of the stack frame of the variable. This method is usually easier to code, but it uses two more bytes per variable access (but fewer bytes to get the address initially) than the first method.

It's your call which method you use. I like the first one because it's smaller, and I've gotten the hang of it already, so it's not a big deal to code with it.
