Hi All
Been a whilst since I played with this stuff !
Above is all good and working except for the internal pullups.....I cannot get them to work.... Commenting the OPTION line out and putting a 10k resistor in place all is ok.
I suspect it is the order that the configuration is in....PORTA, PORTB, TRIS, OPTION, CMCON etc.
Any advice to the right order for above here welcome !
Thank You for reading
