I'm confident that much, much better quality is possible, akin to what you'd find on an mp3 player.

The sound I got on TI-68k with TI-Vibe was already pretty good, I suppose we could get something even better with the TI-Nspire CPU.

Nice I didn't knew about that program. I'll have to try it on my 89T one day

Yeah true, and it's possible to set the Nspire to 150 MHz, according to Calc84maniac. Just don't go overboard, though, because it would suck if a Mario game, for example, grew by 8 MB in size just because of sound Tongue

Put this at the beginning of your code:

Code: Select All | Copy To Clipboard

1
2
3
*(volatile unsigned*) 0x900B0000=0x00000002;
*(volatile unsigned*) 0x900B000C=4;

And at the end, put this to set it back to 90:

Code: Select All | Copy To Clipboard

1
2
3
*(volatile unsigned*) 0x900B0000=0x00141002;
*(volatile unsigned*) 0x900B000C=4;

Yup. I am curious how quick this drains battery power, though...

I don't know if this is just my Nspire, but, in its life, it as gone through at least 10 Ndless 1.1 installs, countless Ndless 1.7 installs (it fails a lot Sad), at least 7-8 hours of usage of gbc4nspire, a lot of hours of use with other Ndless programs, and quite a few hours of usage in school, and I have only had to replace my batteries once.  I don't know if that is just my Nspire (as I know they are notorious for draining batteries), but I find that this thing never needs new batteries.

Wow. I wonder under which circumstances battery power is really drained fast... maybe it just takes good batteries?

We could try to run a program at the 2 frequencies which write regularly its uptime to a file, and see the difference.

If you neglected to reset the CPU to 90mhz, would the OS still run at 150mhz?
