'LCD interface'

Thanks for the reply's about my LCD interface problem.  I never worked out
the problem with using PORTE for the control lines and PORTD for data (ie.
74).  The code that I was using works fine if I change the control port to
either C or D so there has to be an initialisation error somewhere that I
haven't picked up on.

I'm now using PORTC for the control lines and everything seems to be fine.
Thanks again.

You'r lucky to have all those PORTs !!!!    16c74??
I used a 4 bit I/F with 3 control lines -> just 7 bits from PORTB  (on a
16c84 !)

do you guys think that taking code from a BS2 (from Al Williams Stamps
Project of the Month) meant to drive an LCD (HD44780 controller chip) and,
using PICBasic Pro, putting it on a PIC to do the same would work?  thanks.
