Hey people
 I wonder if there is a method of initializing portb for all output on a
16c84 that will not set
the port pins however briefly ? Some pins ok but all pins simultaneously
no.My reason for asking
is I am using 7 bits of port b to control an lcd display 4-bit data then
rs rw e the bit 0 pin is
for output as well (optocoupler) and I am having a lot of trouble from
the hd44780 controller not
acting like it is supposed to not even the simplest routine gives the
expected response and I have
been carefull to keep the rw bit low as I intend to write to the lcd and
not read yet so my routines
do not shift the trisb register after initialization "as yet". During
initialization the portb pins
all go high for two clock cycles.I thought maybe that could be the
reason for my difficulty with the lcd.
 Thanks for your time   Tony M.
