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
