Hi, I see that many glcd have 20 pins, but how does that work out when arduino uno only have from 2-13 on the left side?I have been trying all day wiring a lcd but it wont work and I don't have any pins over for several importent pins my lcd needs.Or have I been doing it wrong all time? Shall I wiring some pins on my broadboard (except gnd/5v)Best regards!
Thanks for the help!liudr, which pins shall not be connected directly on the arduino uno board?CrossRoads, unfortunately I think that board is to big for my model.Best regards!
Thanks for all the help and the other board wasn't so much bigger then the arduino:)Hmm Teensy board look very interesting!Actually the lcd is an RT12864J-1 but that not the point. The thing is that I can figure it out how to connect all the pings when arduino dosn't support it?This is what I want to do: Connect keypad to arduino. Let me type in some numbers, then the LCD shall print out the numbers. But right now I am happy just to get lcd wired up and printing out the glcd big demo.Best regards and thank you all for the help!
