Opcode to set a program as the startup program

Roguebantha 08 Jan 2013 23:32

Is there an opcode to set a certain program to start whenever you turn on the calculator? (minus APD)
You would submit the name of the program in Ans.

I really would like to use such an opcode for my Linux boot system so I don't have to use the startup app every time I want to set this as the default boot. Also, is there an opcode to disable the on break? I'm sure there is.

Hah! I was about 2 minutes from asking about that for Scope. :D

There is an app released by TI that does that, it's called start-up http://education.ti.com/en/us/software/details/en/77EC7DE5D3694F4595C262FDFC2ACC4B/83startupcustomization

Edit: never mind, I just noticed the part of not using the app

Is there an option for Ti-84 Plus Ce? I tried it and it says, "ERROR: SYNTAX"

I know I did a password thingy a while back with calcutil, where it used an onblocker to make it nearly impossible to bypass unless you double-pressed on to turn it on.
tl;dr Calcutil has a run on boot thing but I don't remember how.

Roguebantha 09 Jan 2013 03:18

Yeah, I'm thinking there must be an opcode for it. Even a non opcode would work, since I can always just have the program auto generate it. I know that it writes whatever it is to RAM, but nothing else.

just out of curiosity, why dont you want to use the TI startup app

Oh! Well I'm doing this for my Linux OS and I want it to be able to this by itself for two reasons:
One, it will do it quietly and therefore look more professional and install more like an OS than just an emu
Two, I cannot guarantee that the user will have the startup app, especially those users who have 83's. Doing it from the program looks so much cooler than asking the user if they'd please download the startup app and set Linux as the startup program XD

I'm actually in the process of creating a BIOS for the system, so that when you boot it up, you have different options to choose from :)

ah, i see, well i'll try my best to see if there are other communities who have discussed this, but i cant help, i dont do asm

This is my first OFFSCRPT, so I am glad it is mostly working >.>

That is a bit long, but it works (unless I made a typo). Just put the name of the program in Ans (put an E before it, actually) and run the program. Now turn your calc off, then back on.

It looks like it works, but I ended up accidentally crashing my calc twice ><
I did it, it created an offscrpt, I turned off and on, and the program ran, but on the BIOS screen, appeared for just a second, then immediately went to the actual program. I peered into the OFFSCRPT and found that the last five chars were U.more, which is one of my linux programs. When I did dim(21,"U.more, the calculator crashed. I also crashed it again, when I created an offscrpt using startup, then displayed it, then clicked on its entry. That was a really weird crash actually.

Try to run a regular BASIC program and see if you can run the appvar from that (using BatLib or whatever).

Okay, I'm gonna have to retype in the program again XD Oh well lol

Another reason that I do not want to use Start-Up is that for some reason, it does not work for Scope… I just get some random symbols when I turn it on instead. :/

O_O Is Scope in Pure TI-BASIC right now?

What OS/calc do you have?
I've never had that problem, even using an asm library like BatLib.

That's odd…try updating to 2.55

Also, I was able to make it work by using the startup app to generate an offscrpt, then copying and pasting the offscrpt into my code (as a list so I don't need to store data in an unstable, tokenized fashion). Then I just have the program generate an offscrpt using that. Works like a charm. :D

EDIT:
No wait, this doesn't really work, the person still needs to have start up installed for this to work…:/

After the thread "Glitch in TI-84 Plus SE?," I do not intend to update that high.

I also found another weird bug: I left the Start Up code on for a while with Scope and then, my calc went nut's. Whenever I entered something like a program name, it would start flashing black squares (like the symbols that sometimes appear for a moment when you exit the BatLib app) and would not do anything. I had to reset the RAM to get it to go away.
