I'm trying to run a PIC12F675 with an external 32.768KHz crystal to
maximize
battery life.
I would like to interface to the part with a serial interface. I've tried
300 baud and 110 baud (no partiy, 8 data, 1 stop) but they didn't work.
300
baud gave invalid character returns and 110 baud didn't show anything.
I'm
interfacing with a HyperTerminal session. I have serial input going in
to
pin A3 (I declared NOMCLR in the fuses) and output going out of pin A2.
I can see the program running (as indicated by toggling of a heartbeat
indicator) but the code does not recognize the serial input characters
correctly.
Has anyone tried this "extreme" condition or am I just "spitting into the
wind"? :)
Thanks.
Dave
