Re: TI-H: Linking PIC to TI-89 project
I did want PIC source. I got mine working last night. I am using the TI
protocol as it is the most 'native' to the calc. I can receive anything the
calculator sends out it's port, whereas if I make up my own serial protocol
it will only work with that module and a specific ASM program.
In regard to the 8255 I didn't actually write that document, I just
converted it to HTML for the author, Omar Martinez, martinez@hartford.com.ar
He didn't use a PIC though. However it can be done.
