Here you go.  The compilied version is attached.  It should just turn the PTT LED yellow.  For me, it did not reset the Nspire every time I ran it, but there was no clear pattern with the resets.  Also, I don't think Ndless Version 1.1 works with Nspire Computer Link 1.4.  I tried it last night; it worked perfectly with Link 1.3, but when I used Link 1.4, it said it could not send the loader.  It did create the directory "ndless" on the calculator, though.

#include <os.h>

asm(".string \"PRG\"\n");

int main(void)
{
(*(volatile unsigned*) 0x90110B00)=0x00;
(*(volatile unsigned*) 0x90110B00)=0x30;
return 0;
}


This is only a problem when the flag -nostdlib is added to the ld part of the makefile (I discovered it when ExtendeD suggested it as a fix to the "random" large file size).

When I remove the flag, everything is fine.

EDIT:  Also, the program that gives that error (Trapped) does not even use the static library (I have been too lazy to change it over).

oh so that's why, i bought it this year, so i have to pay an extra $10 damn!!!
 for a keypad

I don't think you have to pay for the 84 keypad.  There is a free offer for it on TIs website if you buy a touchpad one.

Yes, the .c file includeds <os.h>

Even stranger, I went to test this by renaming all instances of memset and memcpy to _memset and _memcpy, respectively, and went into <os.h> and renamed memset and memcpy (the ti-os ones) to _memset and _memcpy, respectively, and it still complained memset and memcpy were undefined, despite the fact that they are not even used by the program at all.

What is confusing me even more is that it is complaining that these two functions are not defiend in a function that does not even use these functions at all.  Here is the error I am getting:

The function "setlevel" does not call these functions at all; drawlevel only calls them in the form of the sprite function and to clear a buffer.

No, you cannot run OS 1.1 without actually using the clickpad all of the time.  You can downgrade fine with the touchpad, but as I said before, trying to use OS 1.1 with the touchpad will lead to an infinite reboot.

You can send things to the 84 keypad using TI-Connect and the USB Cable that connects to the top of the Nspire.

Yes, but only if you have the clickpad keypad.  Otherwise, you will get an "Ndless" reboot.  You can upgrade your OS at any time with Ndless installed.

EDIT:  Also, I should note that you will not be able to open any Nspire documents made on any OS higher than 1.1 if you do downgrade.

I don't think it is worth it to do a title screen at 320x240.  It adds a massive amount of memory to the program (about 30K, if I am not mistaken).  A better idea would be to use sprites used by the program, or simply draw smaller sprites to the screen (or mask them with a background).  That is what I am doing for Block Dude (which will be with the next update when I change to passwords you actually type in).

Beautiful!

Nice to see calculators reaching their maximum potential!
