Filburt's Calculator, part II
 
1 Attachment(s)
Okay, the calculator is now running on an AC adapter and I resoldered the connections for the computer link. And check it out (attached). Now I have to write a program that sends key system variables to the calculator so I can have a little screen on my case that shows CPU usage, memory usage, number of new mail messages, etc. :)

can you install embedded linux onto it?

filburt1 02-17-2003 10:56 PM
If you can write it I would but it only has 27 KB of RAM...

So you probably couldn't run a web server off of it. lol

filburt1 02-17-2003 11:37 PM
What I would appreciate though is if anybody knows how to interface a Visual Basic program to one written in TI-BASIC running on the calculator. Once I get that then I'm set :)

Dominick 02-17-2003 11:51 PM
wait... embedded linux. a web server

I say someone should develop "EMBEDDED vBulletin"

first hack... stickies using the cosine button

filburt1 02-18-2003 12:57 AM
Eh, what the s*** dude:
Code:
PC: 03 C9 0B 00 09 00 00 41 00 00 00 00 00 00 00 4A 00 Request to send Real Number "A"
TI: 83 56 0B 00 Acknowledgement of request
  83 09 0B 00 Clear to send variable
PC: 03 56 00 00 Acknowledgement of CTS
  03 15 09 00 00 80 12 56 34 78 85 25 55 93 02 Variable data: "1.2563478852555"
TI: 83 56 09 00 Acknowledgement of data
     
PC: 03 C9 0B 00 09 00 00 42 00 00 00 00 00 00 00 4B 00 Request to send Real Number "B"
TI: 83 56 0B 00 Acknowledgement of request
  83 36 01 00 03 03 00 Out of memory
PC: 03 56 01 00 Acknowledgement of out of memory
Sounds like fun :(

Dominick 02-18-2003 01:28 AM
umm... clear your temporary internet files. your cache, your history and go to a command prompt

type format C;\

filburt1 02-18-2003 01:59 AM
Installing VB right now (Visual Basic) to try to connect to the COM port and see what magically happens when I send the calculator stuff in its language, and to listen to it say "What the hell did you just send me?". :)

Dean C 02-18-2003 09:14 AM
Lmfao this is all a bit complicated for me :p

Brad 02-18-2003 10:05 AM
Heh i used to play with mine all the time. I wrote a few things for it, mostly so i could cheat in galga and space invaders while i was supose to be listening to the techer in math class :D

filburt1 02-18-2003 04:38 PM
Well I know the calculator is listening because when I continuously hammer it with comm events the cursor stops blinking. I think I'm speaking esperanto though because it doesn't say anything back. Maybe I'm just making lame conversation with it, too.

Chris M 02-18-2003 04:57 PM
Maybe it wonders, like me, what the hell you are going on about;):p

Satan

filburt1 02-18-2003 05:03 PM
Connecting a calculator to a PC so I can use the screen to show stats like memory load, CPU usage, etc.

And ta-da!:

Dean C 02-18-2003 05:14 PM
Why do you want to do that?

filburt1 02-18-2003 05:16 PM
To make a kickass computer mod where I can have the LCD stuck on the front of my computer.

That's a screenshot, apparently :)

Can you make it talk to you like TomBot? That's the question...

If you can turn your calculator into R2-D2, then you have my R-E-S-P-E-C-T... ;)

would you be so inclned as to mod your calculator as a personal communicator. provided I register "filburts-calc-hacks.com


:D

There sure are a lot of calculator nerds out there :)

I have been working on a movie program. I have everything worked out its just no movies to put on :p anyone know how to store the pics as files so you dont have to use RecallPic 1 to show a image on the calc screen

Dominick 02-19-2003 09:05 PM
can you render the movie in ascii?

filburt1 02-19-2003 09:30 PM
You could but the calculator's processor runs at 6 MHz and has 27 KB of RAM so good luck with that.

Also finally got the full thing working. Now I have to figure out how to change the variable's name and value that I'm sending:
Code:
Opening serial port...
Sending RTS...

Not responding to "83 56 09 00"

filburt1 02-21-2003 12:02 PM
...and I've been unsuccessful in that regard :( I can only set variable A to 1.2-something; I can't figure out how to correctly change A to some other variable and value.

Dominick 02-21-2003 12:09 PM
not sure if this is right wrong or indifferent. also dont know what language you are using, but do you have to assign a memory location for the program that you are writing? perhaps the variable you are calling already has that value set in the mem location and you have to write a new one in...

-Dom

filburt1 02-21-2003 12:12 PM
I'm just following a reference I found after days of looking of what to send and receive with the serial port and the variable format I'm trying is getting rejected.
