Hi Rob, would a PIC with PPS help?
Probably not, as port pins are not mapped, only periperal pins.

Would be nice, but PPS doesn't support switching pins of a port.
The bit-by-bit straight-forward method proposed by Kiste like:

    if data0 == 1 then x7 = 1 end if
   {etc.}

is 100% JAL and memory- and cycle-friendly compared to the other methods (while the GLCD library itself is very resource hungry!). I have tested it and works fine.

Since the GLCD_REVERSE_DATABITS will be an option of the GLCD_KS0108 library (and maybe of the GLCD variants) the (extra) code should be skipped properly with a circuit which doesn't require reversed pins. Sounds trivial, but at the moment my second GLCD test board refuses to work properly and I need to fix that.

Regards, Rob.
