I was using a Hitachi HD44780 display hooked up to GPIO pins. Sadly, it got damaged and, in a rush, I had to get a different one. It is a ADM1602U serial enabled display. However I don't plan to use the serial function of it. The pin out diagram is given in the link below
I was wondering if anyone could tell me the difference between the pins of the generic HD44780 display (tutorial I was using for the old display : http://www.raspberrypi-spy.co.uk/2012/07/16x2-lcd-module-control-using-python/) and this new display.
It appears the only real difference is the PGD, PGC, and PGM pins which I am not sure what to connect it to.
