I agree 100%..but I am also looking to see if anyone, with much more experience then I, has had any success sending bytes of data in an 8bit parallel interface. Example seem very hard to come by. All the examples I see are for serial interfaces.
Well this is, perhaps, not quite the best example (but it is a parallel interface for which I have written 'C' code using wiringPi
http://www.cpmspectrepi.uk/raspberry_pi ... erial_Port
and, FWIW, here is some timing info. for the above and other interfaces to the same (or similar) display family (largely influenced by the requirements of the receiving processor
in the LCD module).

Still running Raspbian Jessie on some older Pi's (an A, B1, B2, B+, P2B, 3xP0, P0W) but Stretch on my 2xP3A+, P3B+, P3B, B+, A+ and a B2. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm
