    Kris, I would move the commands "FLAGS=0" and "PAUSE 250" to just above the MAIN loop. There is no reason to be resetting the display every loop. Also I would set the cursor command to be part of the LCDOUT statement as such: LCDOUT $fe.1,"Hello World". And 2100 us. seems a bit long for the command. I have never used anything more than 250 us. in the past and I have used all different kinds of lcd displays from different mfr's.

    Hello,

    Thanks for your reply, though we have messed with the command delays a lot just to see if we could get it working, I'll adjust it and try again now. When I connect it to the oscilloscope it seems that the enable line isn't going high for long enough when using LCDOUT which was interesting.

    I will try now and post the results.

    One last thought Kris, I would like to see the direction registers for your ports as well as the the ANCON register values for the portA port F.
