I've never really given a damn about compatibility with 83+(SE)/84 calcs, since the good old Ti-83 pwnz them all anyway, but I'm afraid I kinda need it this time..
I'm working with a few kids from Belgium who are making their own calculator robot, solar powered and the lot. They rock in hardware, but they didn't have any expertise about the calculator, so they e-mailed me, of course
Anyway, I wrote them their driver software, but it only works on my good old Ti-83, and not on their Ti-83+'s... Which kinda sucks for them...
To get to the point of all of this: I fear that the link port stuff is model dependant. Like I said; I never really gave a damn, so I didn't look into that a few years ago when I wrote my linkport tutorial and stuff. So does anybody know if this is true, and what the difference is exactely? Or are there any serious 83+ tutorials about linking by now? I haven't checked for a while
This works for Ti-83:
Code: Select all
ld a,$D1 ; pull tip low
out (0),a
loop:
in a,(0) ; wait for ring to go low
bit 3,a
jp nz,loop
ret
etc...
