How do you turn the calc off in the battery save mode?
and, is there a command you can place in a loop that will make it save batteries?
i thought that i saw these commands before somewhere, but i can't remember... |

I found nothing on detached solutions, which made mirage work in "battery-friendly mode".
Edit: if the calc is off it's already consuming much less battery power since the LCD is off.

If you wish to turn off the LCD and have the calc sit in low power mode you must output %00000001 to port 3 followed by a halt.
TurnOffLCD:
ld a,%00000001 ;duh I think you know what this does.
out (3),a ;Shuts the LCD off
halt ;Suspends execution until an interrupt occurs a.k.a. [on] key press
ret ;ret to TIOS or main loop
This code will cause your calc's RAM to reset if you remove a battery while it's running.
Another thing I need to mention is that if you are writing a no-shell asm program it will set the onInterrupt flag. It is wise to add this between the halt and ret in the above code.
res onInterrupt,(IY+onFlags)
Otherwise it may generate some undesired results. |

I remembered this from a while ago on the DS website:
Code:
Gen_Checksum:
push ix
ld ix,9D95h
ld bc,60DBh
ld hl,0011h
ld d,h
loop:
ld e,(ix+0)
inc ix
add hl,de
dec bc
ld a,c
or b
jr nz,loop
ld e,d
ex de,hl
sbc hl,de
pop ix
ret
Then
Code:
call Gen_Checksum
ld ($85BE),hl
Will re-calculate the RAM checksum that the TIOS uses to determine if there should be a RAM reset. GetKey does this automatically BTW.
N.B. This will work on a TI-83 Plus. Not sure about TI-83/TI-84 Plus, but doubtless there is a similar variable.

the code for fully turning the calc off (you can ppull the batts out) is
Code:
poweroff:
di
ex af,af'
exx
ld a,1
out (3),a
halt
xor a
out (4),a
ex af,af'
exx
ei
ret

| I have no idea if that code works properly or not. When I posted it, I specifically said that it was a guess. Go ahead and test it but no guarentee's. |

| You can BCALL $5008. That'll turn the calc off. |
