Oh, yes, there are. I had forgot about thoose. Downloaded them now and
checked them over.
looks nice except one thing, they are not complete for using for networking
calcs.
The routines are all for the master side, that only reads and writes to
other i2c devices.
you need to implement the slave side too, on the other calcs.
I don't really like the master-slave model in i2c either, but it could
probably work fine. you probably would have to have a user option for
selecting who is master and such too. not very elegant.
shouldn't be very hard to implement the slave side though, specially if
one uses the i2c routines already written.
This is btw for the ti89.. probably works fine with the 92+ too.
the hardware needed is equal to the "token ring"-model... (that needs more
codeing and more complex such though.)
Best would probably be to program some sort of network lib, that implements
a network stack. could be enough with just 2 levels, one for interfacing
with the program, and one for interfacing with the network. Then one could
change the whole network part totally, if someone comes up with a better
idea for how to handle the physical part, without having to change anything
in the programs useing the net. would probably boost usage of it.
