Just got an Arduino Mega2560, and have a couple of projects in mind, both incorporating a graphic LCD. I jumped the gun, and picked up a Newhaven 240x128 display, assuming that it would be compatible with the Arduino. The pinout makes sense, and nearly matches that of the common LCDs mentioned around here -- except for an "Interface Select Pin", with options 0: 8080 Family, or 1: 6800 family. The controller on the display is a RAiO RA8835. Is this compatible with any of the display libraries available for the Arduino? Wanted to check with the experts here before attempting to connect it.
I'm not able to include a URL in my first forum post, but the display is model NHD-240128BZ-NSW-BTW at newhavendisplay.com.
Did some Googling, and determined that the "Interface Select Pin" is to tell the LCD controller whether its commands are being sent as Little Endian or Big Endian (essentially the order of bits within each byte of data).
Any educated guesses on how to incorporate this into the Arduino code, or if it is even necessary? Presumably if the "endianness" is not changed from one command to the next, the signal (1 or 0) would not need to change for that pin. Could it be left disconnected? I'm waiting on some pin headers to connect the LCD, otherwise I would have been experimenting by now...
