Nspire time
« on: August 29, 2010, 12:02:11 pm »
Is there something to return the time on the Nspire?  Like a function, or a ram area or something?

Yeah, there are memory mapped timers. See here for the addresses. I haven't used the timer, though.

Ok, so what I need it for is to start at 0, and count up, and then check it later.  It seems like I'm going to need to set the bits like this (although I don't know how to in C):
900D0014 (location)
Bits:
00001111

That should: Run the timer, increase timer (instead of decrease), and run infinitely.  Is that correct?

Edit: actually, it looks like ExtendeD posted closer to what I wanted :)  But I still don't know how to read from that spot :/

Code: [Select]
int time = *(volatile unsigned*) 0x90090000
Be warned that this clock cannot measure any interval less than 1 second long.

Oh... ok.  I'll keep this information, I don't think I'll need it just yet, but I might have an idea for a game using this :D
