    The two PICs you mention are very different.
    The OSCs and ADC are two big ones that come to mind.

    Look at the data sheets for both and you will see.

    Then work on blinky. To start use a non analog pin just to finf out if the configs are correct.

    Thanks ... I will pour a stiff drink and study the data sheets ! I checked that both chips had an 8 bit D port and a 3 bit E port and connected the lcd to them. I first checked that I could flash LED's on the D port and that seems OK so I presume the configuration is more or less OK. I will have a look at the osc as you suggest !
    Thanks again

    Are you using the 44 pin demo board?

    Yes I am ! ...and I just chickened out .. Connected the LCD to the default pins on Ports A and B and it now works. I just have now to modify the programs that use those ports unless I can figure out why it doesnt like ports D and E . Many thanks for your input

    Port D on that board goes to the LEDs unless the jumper is removed.
