Re: TI-H: TI-Modem
heheh, but I/O is cheap, why bother... I noticed that the AVRs
(at least the early ones I got) sometimes puke when you change from
output to input and this can mess up TI routines in rare cases.
It can certainly be done, but you probably still need the pull-ups.
You may also want (just to be safe) current limiting resisters so
that the TI isn't outputing a high while the AVR is outputting a low.
This won't hurt the TI link port (because of the way it works,
wired-AND) but it may cause problems for the AVR's relatively weak
output drivers.
I'd love some more info tho, I may need two more I/O lines in the
future. Although I think the module port is robust enough as-is.
