Hi,

I had a similiar problem a while back on two differnet projects, with
both the 16F877 and 16F876.
I'm using the HI-TECH C compiler. I was using a LCD and serial port,
but the code seemed to lock up for some reason. After removing the
serial port initialise funtion, the program worked again. It seemed to
me that the sequence in which the registers of the serial port was
initialised was important. I changed the sequence the registers are set
and the code worked! Had no problems since then. Doesn't make sense, but
it worked.

Maybe try removing your serial port initialise function, or disable it
and see what happens. Hope it helps!

Good Luck!

OK im past frustration and on the verge of writing this crap over from
scratch. Im working on a program that controlls a LCD and communicates
to a
PC via rs232. The PIC as a 16F877. The problem I'm having is when
telling
the pic things to send the LCD, it locks up and stops responding to
anything. It seems somewhat random when exactly it locks up. On lockup
the
USART TX line tri-states(?) (neather high nor low)...and I lack any
debugging tools so I cant see wtf is going on. I'm allmost positive its
a
software thing because I use the PICLOADER bootloader, and it uses the
rs232 i-face for writing the program, and it works just fine. If
anyone
would be willing to look over my program please let me know..Its kinda
large, but alot of it is commented out in my attempt at finding the
problem. Assembled it uses a little over 1K of program space. Please
anyone
who is willing to help out a newbie please speak out.

MUCH thank-you in advance,
Tim Thompson
