OK so, I've been working on this since wednesday and it still doesn't
work. It worked for a little while. I programmed a PIC, debugged some
code, all was great and then bam, no more. No matter what I try, it
just won't work. I even made a PCB for it, and no luck.
I took it to the lab and with the scope in the serial line I tried to
debug it and found some interesting things. The serial port does send
the reset. The PIC gets the first messages and answers them and the
computer hears it and tries (because I see lots of activity in the
computer's TXD when the PIC is on, but not when it's off. But maybe
that can be because of the serial control lines.
One thing that I noticed is that the pic strobes one bit constantly at
a low frequency (I forgot to measure it). Seems strange.
Everything else is OK. The firmware is loaded OK. The pic is a
16F877-20/P. So unless I'm using the wrong firmware, I don't know what
the problem is :(.
I'm using MPLAB 7, windows 98 (on the laptop) and XP on the desktop.
